73b1e30bb0 skin engine: Reduce scope of internal wps_data struct
A bunch of public API calls take a wps_data struct argument,
but that's an internal type that doesn't have a direct getter.
Instead the skin engine provides a gui_wps struct as a way
to refer to a particular skin instance. Use that instead of
wps_data in the public API.

f6c719d7ec replace strlcpy with strmemccpy
replace applicable calls to strlcpy with calls to strmemccpy
which null terminates on truncation

in theory the strmemccpy calls should be slightly faster since they
don't traverse the rest of the source string on truncation
but I seriously doubt there is too much of that going on in the code base

c088a9453d Database: Restore selection in lower menu levels
The database only remembered what you'd selected when
ascending the menu hierarchy again from a lower level.

Now it restores a previous selection going in the other
direction as well, when you enter a new menu, as long
as the selection at the current level hasn't changed.

ffe2df2e92 Implement Rewind across tracks functionality
Useful feature for audiobooks. To rewind from the end of the previous track - press rewind at the very beginning of the current track. So if you are in the middle of the track - first rewind till beginning then release and press rewind button again (Playback Settings -> Rewind Across Tracks option should be enabled)

I have no idea what bug this could possibly "fix", and nothing
looks different on the sim after removing it. As far as I can tell
the Onda has no unique features that could cause the skin engine
to act flaky, so I'm willing to bet this workaround isn't needed.

26ffcd8f9f playback: Fix track resume from file offset
Resuming a track with "Resume Playback" or a bookmark is supposed
to pass both the file offset and elapsed time to the codec. Since
commit dfff938dff the offset has been getting zeroed because the
buffer handle wasn't open at the time of the buf_filesize() call,
causing it to return a negative error code.

Having a valid offset improves resume accuracy with some codecs,
like VBR MP3.

4b7b7a0a83 shortcuts: Reduce SHORTCUTS_PER_HANDLE to 4
The current value of 32 per handle seems excessive. Buflib overhead
per handle is only 20 bytes and a single shortcut is > 500 bytes.
Reducing SHORTCUTS_PER_HANDLE means that minimum memory usage can
be lower when there are a few shortcuts, at the cost of marginally
increased usage for large numbers of shortcuts. This is helpful to
keep memory usage under control for low-memory targets, where 16 KiB
is almost 1% of system RAM!

653082ad1d Database: Adjust "Play Selected First"&"Shuffle" behavior
- With "Play Selected First" and "Shuffle" enabled,
another item was randomly selected when returning
to the list. This appears to be a bug

- With "Play Selected First" disabled, the first item was
selected. This appeared to be intentional, since, at least with
"Shuffle" disabled, that is the item that was played
back. This may not be helpful either, since it makes you lose
your place in what can be a long list. It is also  not
consistent with the behavior of the File Browser. The current
selection should probably be maintained in all cases.

- At least according to the manual and the behavior of the File
Browser, "Play Selected First" should only apply when "Shuffle"
is enabled.

0761532d09 Don't autoload bookmarks after saving dynamic playlist
4f83e66 (FS#13287) introduced a useful option to
immediately re-load the saved dynamic playlist, so that
bookmark creation becomes possible.
(Current Playlist->Reload After Saving)

It seems unnecessary and won't produce the intended
effect to autoload bookmarks after the playlist is saved,
since playback position will be restored to where
it was previously.

Additionally, with "Load last Bookmark" set to "Ask",
the dialog  for choosing a stored bookmark will appear
after the playlist has been saved. The dialog is
unwanted, since:

- Selecting a bookmark doesn't have expected effect
- Selecting "Don't resume" will actually resume
- Cancelling out of the screen will prevent the
saved playlist from being loaded, without this being
obvious to the user
- It causes a crash if the dynamic playlist is saved
from within the Playlist Viewer (both the Playlist Viewer
and the bookmark selection screen use the plugin
buffer)

d5a081cbd1 gui: Remove "enum list_wrap" from list action functions
Removing the "list_wrap" argument is actually pretty easy.
In practice, almost all lists are using LIST_WRAP_UNLESS_HELD
behavior so we can make that the default. A couple of lists
disable wraparound with LIST_WRAP_OFF; this is now achieved
by setting the list "wraparound" flag to false when setting
up the list. LIST_WRAP_ON was unused and is of questionable
value, so it has been removed entirely.

This makes list wraparound behavior a property of the list,
controlled solely by the "wraparound" flag. The result is a
simpler list API and implementation, without changing the
behavior of any lists.

ff378deb69 gui: Remove gui_synclist_limit_scroll()
Since gui_synclist_do_button() overrides the setting at runtime
there is no reason to have a public API call to set it. Really
it should be a local variable, but it will be simpler to do that
after refactoring how list wraparound behavior is handled.

9ce5b2a2ed gui: Remove show/hide selection option in lists
The implementation of the "show_selection_marker" option in
lists isn't great. It's a cosmetic option used to hide the
selection, but it causes the list to do funny things to the
selected_item and doesn't play nice with voiced menus, since
these rely on the selection to determine what item is spoken.

There are only two user-facing lists that use the option, the
"Rockbox Info" screen and a menu in the superdom plugin. The
rest are debug screens, and cosmetics don't matter much there.

Given how little used the option is, and its issues, removing
it seems reasonable.

420fb1163c skin engine: Fix bug with %Vs(color) tag
The %Vs(color) tag doesn't set the text style properly and causes
the background to not be cleared when rendering lines. For static
text this is rarely a problem, but for scrolling text it'll cause
the text to "smear" once it starts scrolling.

Fix this by setting STYLE_DEFAULT, so the background gets redrawn
when the line scrolls.

USB ask mode is basically a footgun: it can't work on native targets

Removing the setting seems like the best solution for now, since a fix

place so the option can be added back later in a non-buggy way.

7345666d9c plugins: use menu for lastfm scrobbler TSR exit callback
Use standard menus and yes/no screen for the TSR exit callback,
similar to the recently added test_usb plugin. This removes the
need to define key bindings and it provides a more consistent
user experience.

It also allows the "flush cache" message to be popped up in the
main thread - doing it from the worker thread is unreliable and
the message often disappeared because the main thread did a UI
update immediately after leaving the plugin.

One issue is that quitting the plugin by selecting the scrobbler
plugin itself immediately restarts the scrobbler. This is because
there is currently no way for TSR plugins to terminate themselves
either through the exit_tsr callback or otherwise.

9e93796407 buffering: remove bufgettail/bufcuttail
These operations can only be used in limited circumstances and have
exactly one user. bufgettail especially seems of dubious value; how
often do you need to read N bytes from the end of a file without
changing the file position?

strip_tags() was the only function using them, to strip off ID3v1
and APE tags off the end of buffered tracks. This would save only
32-192 bytes per track -- if the container format uses APE/ID3v1.
It hardly seems worth the effort.

More importantly, in my experience at least, the Select

e71a441762 ImageViewer: Fix buffer overflow
np_file is a buffer of size MAX_PATH. After
removing only the file name component and
leaving the rest of the path, the
available space may not be sufficient
for appending another file name (possibly of
size MAX_PATH itself) to it.

This can occur after a file of acceptable
length is opened in ImageViewer, and you
then advance to another file whose path
(including the file name) is longer than
MAX_PATH.

To avoid searching the whole filesystem, only subdirectories of the

ddcab156f7 gui_synclist move global display settings to list struct
its really painful needing to override global settings in order to change
some aspects of lists

this patch moves:

[scrollbar position, cursor type,
talk_menus, keyclick,
wrap around, scroll paginated]

to variables within the synclist, it also makes updating
after settings changes a necessity

I think I have the static synclists in core covered

(I think the one in gui/list-skinned can be left as is)

this patch allows easy modification these flags on the fly

8dbc0914f6 imageviewer: limit progress bar LCD update rate
The progress callback doesn't rate limit LCD updates, which causes
excessive slowdowns (up to 150x!) on some targets. Limiting updates
to 20fps solves the problem and should boost load speed across the
board, particularly for large images and animated GIFs that may run
the progress callback thousands of times.

32f1418c5a buffering: fix buffer overflows with bitmap loading
In some circumstances it was possible for a bitmap to overflow its
buffer and overwrite the next handle. The easiest way to trigger it
is with a highly compressed JPEG that is decoded to a large bitmap.
Because the JPEG file size is used to determine how much to allocate
this would cause an obvious buffer overflow when the JPEG is smaller
than the decoded bitmap. Fix this by using the decoded bitmap size as
the allocation size. Some overhead must be added to deal with JPEGs,
but it will be freed once the image is loaded.

A less obvious possibility is the fact that add_handle() will allow
a handle to be added even if there's not enough space for the entire
allocation. This is generally beneficial because it allows the first
part of a file to be loaded while waiting for space to free up, but
for bitmaps it is not valid because the whole image is loaded at once.
Hence if there is not actually enough space in the buffer, the bitmap
load can again overflow the actual free space and overwrite the next
handle.

The buffering code supports an H_ALLOCALL flag for allocations that
need the free space available immediately, so use it for bitmaps to
avoid that bug.

load_image() had a sketchy-looking check for free space which stopped
me from triggering the bug with simple tests, but since guessing the
free space is obviously a bad idea when the caller *knows* how much
free space there really is, remove that guess and let the caller tell
load_image() the real deal.

5aa0fc3b00 jpeg: provide a rough estimate of decoder memory overhead
JPEG decoding requires additional space in the bitmap buffer beyond
what is needed for the decoded pixel data. Provide a way to estimate
how much overhead is needed.

The actual overhead is sizeof(struct jpeg) + decode_buf_size, where
the latter depends on the image size and JPEG encoding used. From my
testing decode_buf_size is normally pretty small (under 5 KiB) but
looking at the code it could be large in some cases, primarily with
large images, so 32 KiB seems to be a decent compromise. Someone who
knows better about JPEG should pick a better value if that's too big.

Using a constant is obviously not the most accurate but it seems to
be the simplest option for retrofitting to existing code.

7718b24401 buffering: fix signed overflow in next_handle_id()
Not sure what the comment is talking about - signed overflow
is undefined behavior and we don't use -fwrapv or other flags
to make it defined. I can't see how a compiler could abuse it
here, but the overflow is nonetheless easily avoided.
