First was an off-by-one bug in the loop over buffers. The condition was
`i < this->hidden->n_buffers', but should have been <=, not <. This wasn't
a critical issue, because the last iteration would check the currently
playing buffer - an unlikely situation.
The second logic bug would make the code always think it had found an empty
buffer, even when it had not, since `idx' was being unconditionally set
every loop, rendering it unusable for a sentinel value. Fix that.

Added fw modifications required to unpack real world player dumps.
Documented more fwu header fields, magic numbers and finite field arithmetics (extended Euclidean for inverse, long division for reducing modulo field_poly).
v3 encryption used is standard RC4 with the key additionally ciphered by the Elliptic Curve Integrated Encryption Scheme.
Either sect233k1 (NIST K-233) or sect163r2 (NIST B-163) curves can be used, with the former overwhelmingly prevailing, being hardwired in SDK's maker.exe. Using a private/public key scheme is superfluous because both are stored in the firmware, with the added level of complexity likely serving the purpose of obfuscation. The private key is generated at random with each invokation.
None of KDF or MAC from ECIES are used, RC4 key is directly xored with the shared secret. The random number r used to calculate rG isn't stored, but that's unimportant since only krG == rkG is actually used in the encryption.

Targets with remote LCDs need to have the lcd scroll driver instantiated,
even in the bootloader.
This is because lcd_remote_scroll_stop() is called, in addition to
lcd_scroll_stop(). This could probably be excised.

This turns on -fwrapv and -fwrapv-pointers.
As per GCC docs:
"This option instructs the compiler to assume that signed arithmetic
overflow of addition, subtraction and multiplication wraps around
using twos-complement representation. This flag enables some
optimizations and disables others."
All of our targets fall under this category.
For some time now we've been using -Wall which implies
-Wstrict-overflow=2, which only warns when the compiler actually
implements a possibly questionable optimization, so I'd expect this to
not affect our code size at all.

When data is not in packed-16-bit mode, flushing the fifo
may result in swapping left and right channels if there
happens to be an odd number of entries in the FIFO.
This is especially likely when switching sample frequencies
for some reason.
When stopping PCM DMA, disable DMA and Underrun Interrupts
and then wait for FIFO to be empty before stopping AIC's playback.

Control cache entries cost 24 bytes per command, but cacheable
commands are always less than that when written out to the file.
We can actually cache *more* data by writing commands directly
to the fd (native Rockbox has a 512-byte cache per fd) and it's
much simpler.

The intent behind the check is to only do this if the filename
comes from an on-disk file. With the RAM buffer is gone this is
now "always" the case.

This checks for an out of memory condition when the filenames
were buffered in RAM. The playlist no longer buffers anything
in RAM so the code is unreachable.

Use the playlist control file for directory playback instead of
storing filenames in RAM. The implementation of that feature is
very iffy and probably responsible for random crashes that may
occur when skipping through directories rapidly.

GCC 4.9 always emits assembly with divided syntax. Setting unified
syntax in inline assembly causes the assembler to complain about
GCC's generated code, because the directive extends past the scope
of the inline asm. Fix this by setting divided mode at the end of
the inline assembly block.
The assembler directives are hidden behind macros because later
versions of GCC won't need this workaround: they can be told to
use the unified syntax with -masm-syntax-unified.

Any modifications to the playlist (insert, delete, shuffle, etc)
will cause the modified flag to be set. The flag is cleared when
the playlist is saved. Code that generates playlists can manually
clear the modified flag if appropriate; there is now a proper API
for this so the tagcache and pictureflow don't need to resort to
hacks.

ABI breaking changes. Additions to the API won't need to touch
the version number, resulting in fewer merge conflicts.

Make 4.3 and newer doesn't interpret comments in a shell call,
whereas Make 4.2 and older do. Escaping the comment directly
works on old makes, but on new makes the backslash is passed
as well -- which we want to avoid.
The safe way to pass a literal "#" character to the shell on
both versions is by embedding it in a variable and expanding
that. It's ugly, but it works...

Enabling locked actions for all softlock targets accidentally
broke keylock on touchscreens because the generic touchscreen
keymap was missed. Trying to lookup CONTEXT_WPS|CONTEXT_LOCKED
returned the mapping for CONTEXT_STD because the locked version
wasn't explicitly handled.
But on almost all cases, a context's keymap does not change when
the screen is locked. It makes more sense to mask out the locked
flag and only check for it where needed.

stupid bug on my part font_filename was pointing to a movable

instead pin the internal calls to core_get_data and
remove font_filename in favor of a function that checks if a

store tag length to shortcut strcmp
this is nearly as fast as making a hash table using gperf
its not the hottest path but its
even slightly faster to shortcut
based on string length
if (tagstr_len > match->len)
continue;
else if (tagstr_len < match->len)
break;
but I found no measurable difference
I don't think its worth the extra constraint of keeping tags sorted
