fast math optimization patch
...one exhaustive testing (and I'm not 
the world's
most critical listener).
   Here is 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...
