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.

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.

don't stop playback to alloc viewports for the keyboard
For the moment it doesn't make much difference
each vp takes about 40 bytes (double that in the sim?)
so not the end of the world 120 extra bytes

- Update the manual entry for PictureFlow with
the latest features and fix keymap
- Strongly suggest enabling the database's
"Load to RAM" feature (in my experience, this
can lead to a ~60x speedup when building the
album index)
- Suggest enabling the dircache, as it can
noticeably improve the loading times for
album art.

While the track number is limited to 99, I know of no documented
constraint on the value of offset minutes to 99.
As we are storing the millisecond offset as unsigned long, assuming
32 bit, we can allow 70,000 minutes (2^32 / 60000).
However, I've been unable to generate a test audio file 48 days long
under 2GB, so I've set the limit to 30,000 minutes.
In addition, this change reduces the maximum number of seconds to 59,
and frames to 74.
I've generated some silent test files with the filenames being
cue_[minutes].mp3

MEM_ALIGN_ATTR should take advantage of cache line alignment on
all native CPUs which define it, not just ARM CPUs. (This could
arguably be done for hosted targets too, but we don't necessarily
know the size of a cache line there.)

Hold "Play" to boot the OF, or boot it from the recovery menu
by holding "Vol. Up". If you had the hosted port installed on your
player before installing the native port, you'll still have to go
through the hosted bootloader.
A couple notes:
- When booting from the menu, the recovery menu disappears, then
reappears before going into the OF.
- You need to hold the play button for like a half second after the
blue light comes on in order to get into the OF.
The recovery appears to be there, but it doesn't seem to be intended
for end users - it just says "Updater V1.1 - Insert TF Pls". I haven't
tested it beyond seeing that it boots, so I'm going to comment it out
for now.

The comment regarding Windows paths was fairly confusing as to
its intent. What the code is trying to do is replace the drive
letter with the volume containing the playlist, which appears
reasonable. The middle of the comment was devoted to explaining
why the code below was potentially incorrect which only served
to add to the confusion.
AFAICT the last volume specifier in a path will cause search to
start from the root of that volume, so any incorrect result can
be avoided by using the new function path_strip_last_volume().
Finally, add a comment at the top of the function that explains
what it does.

This gets the volume that the path eventually refers to by parsing
the last volume specifier and returning the part of the path after
it (which does not contain any volume specifiers). The initial part
of the path therefore contains everything up to and including the
last volume specifier.

Enables multiboot for the FiiO M3K, Shanling Q1, and Eros Q native port.
Note this requires an up-to-date Rockbox _and_ bootloader.
Usage instructions will (eventually) be found on the wiki:

Searching in volume 0 is necessary for multiboot targets with only
one drive, like the M3K/Q1/ErosQ. Without this the search code will
never look at the redirect file on these targets.
The search bound is configured with a setting MULTIBOOT_MIN_VOLUME,
which defaults to 0, but is defined to 1 for Sansa players so they
keep their old behavior.

Now offers sorting by:
- Album artist, then album name
- Album artist, then album year
- Album year
- Album name
Years are determined by the most recently
released track appearing on an album, if the
value differs between tracks.
On the M3K, instead of by going into Settings,
volume buttons can also be used for quickly
adjusting the current sorting

There should be no need for any compatibility hacks since this
value was mostly used internally between the SPL and bootloader.
clk_init() was the only user in the main Rockbox binary which
accessed it, but when loaded by the Rockbox bootloader that code
will not be reached since BOOT_FLAG_CLK_INIT is already set.

Bad blocks in a kernel flash partition seem to be handled by skipping
ahead to the next block; this is a common bad block management scheme
for simple software like bootloaders (and is the default method for
reading NAND partitions in u-boot).
