Some assembly routines don't work on Thumb as-is. For now
just disable these so the codecs compile.
Affected codecs:
- libflac
- libmad
- libspeex
- libtta
- libwavpack
A few DSP routines need to be disabled for the same reason:
- crossfeed_process
- crossfeed_meier_process
- resample_hermite
- filter_process
- sample_output_stereo

This makes these files compileable, or in some cases less
broken, on Cortex-M targets.
In lcd-16bit.c, newer versions of GAS complain about the
infix condition codes so we use the suffix form instead,
which requires unified syntax to compile on GCC 4.9.

calculating inside a function makes it work
adding FORCE_INLINE makes warning reappear
anything else in bounds of the array asounds ok but has digital
distortion so pretty confident the code is right

This reverts commit b14056e90f.
Reason for revert: Not mathematically equivalent, inconsistent with other code paths, and leads to audio artifacts on ARM targets.

synth.c is using a negative offset which gcc doesn't like
equlivalent code just uses pointer math instead

Implicit promotion of integer literals to unsigned long introduced a subtle bug
on 64-bit systems due to weird sign extensions (leads to audible glitches in a
few files). The table is originally designed for unsigned 32bit integers, and
it works with those so use them. As a consequence the lookup table size is
halved as well.

Since gcc 4.4 the MIPS port no longer recognizes the "h" asm constraint.
It was necessary to remove this constraint in order to avoid generating
unpredictable code sequences. We can achieve the same effect using
128-bit types.

librbcodec users must provide these two files when the library is built.
rbcodecconfig.h provides configuration #defines and basic types, and
will be included by public librbcodec headers, so it must not conflict
with the user's code. rbcodecplatform.h provides various OS functions,
and will only be included by source files and private headers. This
system is intended to provide maximum flexibility for use on embedded
systems, where no operating system headers are included. Unix systems
can just copy rbcodecconfig-example.h and rbcodecplatform-unix.h with
minimal changes.
