Rather than holding intermediate results as fixed-point, this converts them
directly to normal integers (in the range of the PCM sample) while mixing,
instead of waiting till the end to perform a separate shifting step. Also,
this precalculates some constants in the reverb code.

This allows CPU load to drop below 100%, which is good for anything
that scales frequency and voltage based on CPU load. Also conserves
some energy by letting the core go idle if there aren't any available
buffers.

Using the coprocessor was a good idea in theory, but didn't actually work.
This moves all SDL threads to the main core, which isn't ideal, but at
least works. Additionally, this also adds some good-practice stuff such as
setting the default sample rate on exit.

This is attempt to simplify porting programs to rockbox (as plugins).
Currently this compat layer implements:
fopen(), fclose(), fflush(), fread(), fwrite(), fseek(), fseeko(),
ftell(), ftello(), fgetc(), ungetc(), fputc(), fgets(), clearerr(),
ferror(), feof(), fprintf()
In order to use it you need to include in ported sources
"lib/stdio_compat.h"

This brings a various small changes to the drawing and input code,
as well as a brand new "mouse mode", where input goes to a virtual
mouse cursor. Only Loopy has this mouse mode enabled by default,
while other games have it hidden away under the debug menu. Some
changes by me to Palisade were required to make it playable; those
are included here as well. Right now, sgt-net is pushing the c200v2's
upper limit on size and may have to be dropped in a future commit.

The new vuprintf makes unnecessary workarounds due to formatting
limitations. I checked grep output for whatever appeared to fit
but it's possible I missed some instances because they weren't
so obvious.
Also, this means sound settings can dynamically work with any
number of decimals rather than the current assumption of one or
two. Add an ipow() function to help and take advantage of dynamic
field width and precision. Consolidate string formatting of sound
settings.

Both blitter_save() and blitter_load() functioned incorrectly when
zoomed in -- blitter_save() would copy from the wrong location, and
blitter_load() would ignore the y-coordinate of the destination.

This adds no functionality, but instead cleans up the source and adds
some more substantial documentation.

This fixes two separate bugs: The first was that the drawmode was not
reliably set when drawing the title, occasionally leading to a black
rectangle where the title should be; the second that the title bar's
space wasn't being cleared before drawing, leading to artifacts when
the length of the title string changed.

This adds colored font rendering, as well as a workaround for font
loading while zoomed. Additionally, the frontend has been modified to
match the new upstream API.

This adds a "Zoom In" option to the pause menu of each puzzle, which
displays the puzzle at triple size (subject to change). This should
help with tiny screens, modulo memory concerns associated with
allocating the temporary framebuffer to which drawing operations are
redirected. Coincidentally, there's an upstream bug with Map that
causes the cursor's positioning to be incorrectly displayed when
zoomed.

Simply extends the current isqrt() to be able to do fractional bits
and improves the initial estimate using clz(). iqrt() itself is
no more and is equivalent to fp_sqrt(x, 0). The original also had
a small bug where the guess comparision should have been >=, not >.
Uses no large integer math or division and is very accurate
(simply returns a truncated fraction).

The dereference of entry->name was originally omitted, which meant
that only the password would ever be displayed.

This brings puzzles up-to-date with Simon's tree, along with the
rockbox-specific changes I made. Note that I also got rid of some
of the ugly floating-point code in rbwrappers.c and replaced it
with wrappers for our fixed-point library.
