Because usb_core_legacy_control_request() is called by an
interrupt handler the global variables used to track the
current control request at the very least need to be volatile.
It might also be necessary to disable IRQs but I'm not sure
of that.

save to a .tmp file on save and rename on next load
I think this should pretty minimally invasive as the same file
still gets overwritten in subsequent attempts until it is loaded again
the save path is still static
so it won't cause issues holding up shutdown.
load might be a bit slower with the searching for tmp+current file
and renaming them
Plus there is now a backup of your last settings file

we shouldn't need to save the last_screen unless the plugin were to
bypass the normal shutdown procedure
if its a crash do we really want to resume the plugin?
its it is intentional save the settings prior.

since the plugin browser now exits before running plugins
it has already loaded the dest data for the plugin
the plugin will be run from the root menu with the open_plugin run key
BUT, since the calls originated from the shortcuts menu
it overwrites the run key with its own
this patch allows the shortcuts menu to overwrite the dest
key as well so it can run the loaded plugin

recent changes broke shortcuts when they originated from the root menu
I mistakenly thought GO_TO_ROOT only happened at start and otherwise was
GO_TO_PREVIOUS
this commit also adds a few missing features for Start In Previous
to resume the last plugin running at shutdown
Additionally GO_TO_ROOT now overwrites the global last_screen so you can
return to the main menu on next startup

The onplay-context was previously not reset when using the playlist
viewer, which led to a bug if onplay() was last called in the context
of the database. If you then tried to insert songs into a dynamic
playlist using the playlist viewer, a selected track from the database
would be picked, instead of one from the displayed playlist, due to
special behavior of add_to_playlist() within the database context.

now that the plugin browser is resumable
exit it before running plugins
this causes a problem with the open plugin
shortcuts that call other plugins
but its now handled in count limited loop
so plugins can run plugins in a chain
and overall with less overhead too..
the problem remaining --
the plugin exits on USB, returns to ROOT
the browser resumes the
directory next time you select plugins
making for an unwanted auto return

I noticed the way filetree switch was modified
for the lua (and then) opx and open plugin viewers
since builtin files are assumed to be handled in the filetree switch
what if instead filetype_get_plugin() could search the available viewers
this could probably be extended further with selectable defaults

Adding a checksum over the struct offset will allow checking
for compatibility across machines rather than using packed structs
to ensure compability
For any file created by the user from the device this isn't really a concern
But for files between machines, across installs (sim v device),
possibly even across compilers this at least will alert the user
rather than returning junk data

OST timer fix (7a5130a277) causes a boot failure on some units,
the battery voltage reading needs more time to stabilize.

The battery stabilization delay call seems to need to be
about 170 at minimum now, let's do 190 for safety (+20ms).

It turns out the prescaler fields in OST_CTRL are 2 bits wide,
not 3. The programming manual (as usual) is ambiguous and its
diagram shows 2-bit wide fields, but the bit positions in the
text give a 3-bit wide field. Ingenic's Linux code and my own
testing shows that they are, in fact, 2 bits wide.
This caused the OST2 divisor to be 16 instead of 4; the OST1
divisor was correct. This means that all udelay/mdelay calls
took 4x longer than they should've. After this change the OST2
prescaler will be 4, as intended, and udelay/mdelay calls will
wait for the intended duration.

This boosts USB transfer performance a bit, ~10% for reads and
~25% for writes, for large-ish file transfers. Rockbox is still
around 33-50% slower than the OF.

When performing an OUT transfer which is not a multiple of the
max packet size, the last packet of the OUT transfer should be
a short packet. However, there's no guarantee the host sends
the expected amount of data in the final packet.
The DWC2 USB controller handles this case by accepting any size
packet and copying it out to memory. So if the packet is bigger
than expected, it'll overrun the caller's buffer and Bad Things
will happen.
The USB 2.0 spec seems to endorse this behavior. Section 8.5.1
says "an ACK handshake indicates the endpoint has space for a
wMaxPacketSize data payload." So it is possible that other USB
controllers share the DWC2's behavior.
The simplest solution is to force all USB RX buffers to be big
enough to hold the transfer size, rounded up to a multiple of
the max packet size. For example, a transfer of 700 bytes would
require a 1024-byte buffer if the MPS = 512 bytes.
