Add -D_XOPEN_SOURCE=600 to host cflags to make the constants in math.h
available. Include math.h where necessary and remove redundant M_PI
defines.

WMApro actually support 13-bits block sizes (potentially even up to 14),
and thus we should support that also. If we get block sizes beyond what
the decoder can handle (14 is possible depending on s->decode_flags),
error out instead of crashing.

These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.
