This does the opposite of dostime_mktime, converting time_t back to
the two dos date time values. We use gmtime_r for native because that
is what is available and acts the same as localtime_r on other platforms
with a regular libc available.

AVR interrupt signal can remain active if the state has changed during
state read. In such case, there won't be intterupt and the interface
would appear unresponsive until AVR thread received event (e.g. USB
connection/disconnect). Solve the issue by not waiting for event if AVR
interrupt signal is active prior to event wait.

Make it possible for target to provide voltage, percentage and time to
empty values. The voltage measurement is nice to have in debug menu even
if the actions are taken only based on percentage. Perform battery level
estimation based on voltage only if percentage is not available.
Use time to empty based on actual power consumption. This makes the
estimated runtime displayed in Rockbox Info to react to backlight
setting. The bq27000 updates time to empty estimate every 5.12 seconds
so it is possible to see the estimate with backlight off on the screen
if user enters Rockbox Info, activates hold switch, waits 11 seconds and
releases the hold switch.

This provides rudimentary support for parsing the contents of a ZIP
file. For now this just supports uncompressed file entries but DEFLATE
support is planned. This also only implements a low level public API
so more work will be needed to make it usable by application code.

This moves the time conversion function to timefuncs since it has
uses on ports that don't use the FAT driver. This function has no
dependency on the FAT driver as it is so this should not cause any
issues. To reflect this separation the function was renamed to
dostime_mktime since it is really for DOS timestamps. The places
where it was used have also been updated.

This fixes a mysterious, long-standing crash that's been bothering me on
ipod6g for ages: a silent stack overflow in the sound mixing thread (which
is triggered upon loading a new sound, apparently) will thrash the memory
which is located directly before it in the address space.
In this case, it was the SDL_ButtonState variable which stores the mouse
button state that was being trashed. This was manifesting itself by making
the player always run forward, since MOUSE2 is mapped to +forward by
default.
Fix this by quadrupling the stack size of SDL-spawned threads (not the main
thread) from 1 KB to 4 KB.

This new design saves on binary size and stack usage. The API is
also block- and page-based, requiring awareness of the chip layout
to use properly. Out-of-band areas are also exposed for reading

The byte-oriented routines are kept for compatibility with the
existing installer and SPL.

If the commands repeatedly fail it is likely that the AVR is not
programmed. In such case simply continue normal operation. This is
especially important in bootloader as it makes it possible to load new
rockbox build using bootloader USB mode. Otherwise, the only recovery
option would be to use I2C serial.

The old way of padding out bars was to just create a bigger touch
region, the intent being to make it easier to touch the end of a
bar. Unfortunately, this didn't even accomplish that, and caused
an annoying offset between the bar graphics and the touch point.
New method is to account for padding explicitly and clamp touches
in the padding region so they are within the proper touch region.

This uses an equivalent algorithm but with a different initial value
than we normally use (all bits off vs all bits on). Use the new crc_32r
to replace the original MI4 crc32 implementation.
This frees up some extra space on mi4 targets which gives us more
room on a few very space constrained targets (sansa c200/e200, etc).

This uses the reverse of the polynomial used by the current crc_32
function. The code for this was derived from the implementation used
by tinf. This version is space optimized and should be a good way to
reduce code duplication in other parts of rockbox that use the same
crc32 algorithm. This is mainly of use in areas where DEFLATE is in
use.

The old code would seek forward by the frame length, expecting to see a
frame header there, perform a validity check, and then seek back to the
current header.
Unfortunately this doesn't handle situations where there is extra padding
between the frames, leading us to potentially read garbage, causing the
validity tests to fail and rejecting the file outright.
Instead, keep track of the previous valid header/position, and if we find
"valid" headers in a row return the first after seeking back to it.
This change allows the file referenced in FS13299 to be properly parsed, but
further work is needed to get the file to be playable. (file reports itself
as layer 1, variable bit rate, variable sample rate!)

Disabling double buffering results in expected CPPI TX behaviour. With
the double buffering enabled, sending single ZLP resulted in two ZLPs
being available. The two ZLPs is problematic because this causes Windows
to reset USB device after failed SCSI command.
The problematic sequence on Windows 10 was as follows:
* Host sends SCSI Mode Sense(6) Informational Exceptions Control(0x1C)
* Device sends ZLP
* Device sends command failed response
With endpoint double buffering enabled the ZLP was read twice by host.
As host was expecting command response on the second read (and got ZLP
instead), host attempts recovery by resetting USB device and retrying.
