2c2e261648 Use system headers a bit more: use host's fcntl.h for O_RDONLY etc.
Removes the need to fix up those in the simulator.

Also work around some posix-mingw incompatibilities (e.g. getcwd()).

a89fea6754 We already build with -fomit-frame-pointer so there's no need to specify that again.

45c7498f59 FS#11335 by me: make ARM assembly functions thumb-friendly
We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+

Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734

8cb4183839 Put decoder array into IRAM. Improves Coldfire (h300) performance 218MHz ->102.84 MHz. Should be realtime on all CF targets.

0f5c6d47d4 add True Audio (TTA) codec
decoding speed iPod video ~153%
But in some players, the decoding speed is not enough.
(e.g., H180 52.4% (thanks amiconn), H300 55.09% (thanks n1s))
