* completely restructured source tree
* implemented multi channel support
* implemented instrument manager, which controls sharing of instruments
  between multiple sampler engines / sampler channels
* created abstract classes 'AudioOutputDevice' and 'MidiInputDevice' for
  convenient implementation of further audio output driver and MIDI input
  driver for LinuxSampler
* implemented following LSCP commands: 'SET CHANNEL MIDI INPUT TYPE',
  'LOAD ENGINE', 'GET CHANNELS', 'ADD CHANNEL', 'REMOVE CHANNEL',
  'SET CHANNEL AUDIO OUTPUT TYPE'
* temporarily removed all command line options
* LSCP server is now launched by default

* src/eg_vca.cpp: added following transitions to the envelope generator:
  'Attack_Hold' -> 'Release', 'Decay_1' -> 'Release' in case of a release
  event
* EG1 parameters 'Attack Time', 'Release Time' and 'Sustain Time' are now
  controllable by a MIDI controller defined in the .gig file
* src/voice.cpp: fixed bug in pitch calculation which caused new triggered
  voices to be played back without honoring the current pitch bend value

* src/gig.cpp: fixed looping informations ('LoopStart', 'LoopEnd' and
  'LoopSize')
* src/voice.cpp: pitch sample according to keyboard position only if
  keyrange > 1 key, this was the reason that some gig files were horrible
  detuned
* src/audioio.cpp: bigendian specific fix
* src/ringbuffer.h: removed kernel header dependency by adding own atomic.h

* 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

gig.cpp, gig.h: added method GetInstrument(uint index) to class 'File'
which is needed for the new command line switch --instrument in
linuxsampler.cpp (forgot this to commit with the recent commit batch)

* 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

* 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

* 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
