Since sizeof(long) == 4 even on 64 bit Windose, big files cannot be
loaded natively via the ANSI C file API. This change makes fluidsynth's
file callback API use long long, which is guaranteed to be at least 64
bit wide.
- memset should clear all the memory
- end position should be at the end of sample data

This change moves the Ogg Vorbis decompression to fluid_sffile, so that
this is the only place where we have to deal with compressed audio.
It also changes the way the samples are loaded for SF3 files: previously,
the compressed data was copied into memory, then the individual samples
were decompressed (resulting in both compressed and decompressed data to
stay in memory). Also, decompressed data wasn't cached, so previous loads
of the same file ran the decompressed again for each sample.
After this change, the vorbis decompression is changed so that it reads the
compressed data directly from the Soundfont file. And the resulting WAV
data is stored in the sample cache.
They were only used in soundfont loading code, so are probably a remnant
from Smurf. The rest of the FluidSynth code doesn't use underscore
functions, so remove them here as well for consistency.
Also use single quotes in double quoted string, to remove the need for
escaping chars.
