df3bab0b40 Only import instruments once from Soundfont 
This changes the way instruments and their related information is imported
from a Soundfont. Previously, each preset zone got a complete copy of the
instrument and related information, wasting a lot of precious memory.

After this change, an instrument and related information is only
imported once and then linked into all preset zones that use this
instrument.

c4003bef39 Store mutable information about inst zones in new fluid_voice_zone_t struct 
This change separates the static instrument zone information read from
the Soundfont from the information that gets modified on import and
later via the legato handling. It opens opens up the possibility of
having unique instruments that only get imported once and then linked
into the individual preset zones.

073da2141c Implement dynamic sample loading 
This change adds a new feature that enables loading and unloading of
sample data on demand. As soon as a preset is selected for a channel, all
of it's samples are loaded into memory. When a preset is unselected, all
of it's samples are unloaded from memory (unless they are being used by
another selected preset).

This feature is disabled by default and can be switched on with the
"synth.dynamic-sample-loading" setting.

a985c68a13 Enable decompressed Ogg Vorbis samples to be stored in sample cache 
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.
