* implemented parser for the LinuxSampler control protocol (LSCP) by using
flex / bison (where src/network/lscp.l is the input file for lex / flex
and src/network/lscp.y is the input file for yacc / bison), parser and
scanner can be regenerated by 'make parser'
* implemented LSCP network server (only single threaded so far), LSCP
server will be launched if LinuxSampler was started with "--server" flag,
implemented the following LSCP commands so far: "LOAD INSTRUMENT", "GET
CHANNEL VOICE_COUNT", "GET CHANNEL STREAM_COUNT", "GET CHANNEL
BUFFER_FILL", "SET CHANNEL VOLUME" and "RESET CHANNEL"
* disk thread now started within the engine

* implemented bidirectional voice state transition, means voice state can
switch arbitrary times between 'Sustained'<-->'Released' within it's life
time, thus the release process of a voice can be cancelled
* src/eg_vca.cpp: extended envelope generator by additional states
('Attack_Hold', 'Decay_1' and 'Decay_2')
* applied patch from Vladimir Senkov which adds new command line parameters
('--jackout', '--alsaout' and '--samplerate')
* configure.in: fixed compiler warning

* introduced time stamped events
* implemented jitter correction
* added pitchbend wheel support
* src/audiothread.cpp: using voice pool instead of a voice array, makes
voice allocation more efficient and code more readable
* src/rtelmemorypool: redesigned, added some new methods and pool is now
derived from list

* Added JACK support: Audio rendering process is now callback based and
independant of used audio output system. Interfaces to other audio output
systems can be added by creating a class derived from abstract base class
'AudioIO' and embedding the new class into linuxsampler.cpp.
* src/audiothread.cpp: applied patch from Vladimir Senkov which fixes
hanging notes in conjunction with the sustain pedal

* implemented amplitude envelope generator
* src/voice.cpp: some .gig instruments still sounded detuned, I hope
finally to have this fixed now

* implemented looping; RAM only loops (that is loops that end within the
cached part of the sample) are handled in src/voice.cpp whereas
disk stream looping is handled in src/stream.cpp and is mostly covered
there by the new ReadAndLoop() method in class 'Sample' from src/gig.cpp

* src/audioio.cpp: added support for Alsa 1.0.0
* src/audiothread.cpp: fixed several bugs in sustain pedal handling
* src/diskthread.cpp: fixed several bugs which occured under extreme
conditions (endless loop in audiothread, freezing the whole application,
outage of available disk streams)
* src/voice.cpp: fixed cubic interpolation (disabled by default; you can
enable it by setting USE_LINEAR_INTERPOLATION to 0 in src/voice.h)
* src/configure.in: added check for Alsa version

* implemented velocity->volume mapping: samples are now played back with a
volume appropriate to the velocity of the triggered key, the velocity
curve transformation functions (in src/gig.h) used for this are so far
only an approximation to the ones from Gigasampler

* rewrote sustain pedal handling: instead of just queuing the note-offs I
added a sustain pointer for each midi key which starts to point to the
first active voice on the respective key and increments to the next voice
on the key when a note-off arrived, the release velocity value will
immediately be stored in the respective voice object (this also fixes the
segmentation fault issue when the sustain pool was full)

* src/gig.cpp: fixed bug in decompression algorithm which caused it not to
detect the end of a stream and let the disk streams reload forever also
resulting in strange sounds at the end of disk voices (concerned only
playback of compressed gig files)
* src/audiothread.cpp: deallocation of voices when they reached the end of
playback (thus e.g. when sustain pedal is pressed and a disk stream
reached it's end)
* various endian corrections needed for non intel systems
* introduced debug level, you can set the debug level and thus the
verbosity of LinuxSampler in src/global.h

* src/audiothread.cpp, src/audiothread.h: added Sustain Pedal support
implemented by postponing note-offs and leting multiple voices play
on the same MIDI key.
* added the RTELMemoryPool Class which is a fast RT-safe memory allocator
and list manger
* src/linuxsampler.cpp: added a voice and stream counter debug message

* transition from plain Makefile to autotools, source files moved to src/
* configure.in: added test for x86 architecture
* src/voice.h: x86 specific asm optimization for double to int casts only
if compiling for x86 architecture
