fast math optimization patch
...the blow by blow description of the patch: - Add fast_math.[ch] - fast_rsqrt_est -- fast reciprocal square root estimate (i.e., 1.0/sqrt(x)) - fast_sqrt_est -- fast square root estimate - fast_log_est -- fast natural log estimate - Adds a IEEE structure for floats - Adds VORBIS_EXACT_FLOAT_RESULTS. If this is defined, the estimations are turned off. - Modify os.h - Remove _V_IFDEFJAIL_H_. The entire file is already in an _OS_H ifdef, so this shouldn't be necessary. - Added normalized processor ifdef support (VORBIS_X86 and VORBIS_PPC so far). These control...
