* lscpserver: we now only use one instrument loader thread; commands for
loading instruments in the background wait in a queue to be processed one
by one to avoid possible race conditions and to improve I/O efficiency
* fixed possible race condition while streaming with multiple disk threads
by using an own decompression buffer for each disk thread
* libgig: fixed some memory leaks caused by non virtual base constructors

* some fixes regarding the filter (fixes the "silence" bug which occured
occasionally, caused by random biquad parameters which lead to unstable
filter equation and thus to infinit filter output results)

fixed cases in_start = in_end = CrossfadeControllerValue, fixed curve for
cases out_start < CrossfadeControllerValue < out_end, honoring
InvertAttenuationController parameter)

into the engine's process chain (fixes forced segfault in EGADSR)

differentiation if event might happened before or after current fragment

* configure.in: added check for UNIX98 compatibility, check if there's at
least one supported MIDI input and audio output system available, added
conditionals for ALSA and JACK
* src/drivers/audio/Makefile.am: ALSA and JACK drivers are only compiled
respectively if they're supported by the system
* MidiInputDeviceFactory.cpp, AudioOutputDeviceFactory.cpp: little
workaround for reported linker problem
* removed autotools generated files from CVS

from signed 7 bit to signed 8 bit)
* src/linuxsampler.cpp: stacktrace is now automatically shown on fatal
errors (that is segmentation faults, etc.), gdb should be installed for
this to work
* gig::Voice: tiny accuracy fix of pan calculation
* replaced old pool classes by completely new ones which now offer
Iterator abstraction

* added first two experimental voice stealing algorithms ('oldestkey' -
which just steals the oldest voice on the oldest key and 'keymask' - which
tries to pick the oldest voice on the same key where the new voice should
be spawned, if it fails it behaves like 'oldestkey'), the desired algorithm
can be selected at compile time (see Engine.h) will be configurable via
LSCP soon though

reduced EG_MIN_RELEASE_TIME to allow to finish kill process of a voice
within the same audio fragment, this will be e.g. be mandatory for voice
stealing

drum patches and monphonic instruments

stick the note on event to the respective key's own event list although
e.g. the EGADRS expects it to find there

* Load Instrument patch applied; this patch makes the
LOAD INSTRUMENT command to return immediately,
almost/always with an OK response, while spawning
the proper instrument file loading in the background.
* New INSTRUMENT_STATUS field on GET CHANNEL INFO result
set; the instrument status value holds the load progress
percentage if positive, otherwise a negative value is
evidence of a load exception error.
* VERSION is now set to 0.2.

* src/common: added template class 'optional<>' which can be used e.g. as
return type whenever a value might be returned, but don't has to; this
template class pretty much acts like a pointer of the given type, but is
much more safer than a simple pointer
* src/audiodriver: added static class AudioDeviceFactory to create audio
devices at runtime by using a string and to obtain driver informations
of drivers at runtime, driver classes should simply use the macro
REGISTER_AUDIO_OUTPUT_DRIVER(DriverName,DriverClass) in their cpp file
to register the driver to LinuxSampler (no changes needed anymore in the
LS code to add a new audio output driver)
* src/drivers: added classes to dynamically manage driver parameters; there
are two different kinds of parameters: parameters which are need to
create a new device (DeviceCreationParameterX) used to e.g. create an
audio output device or a MIDI input device and parameters which are only
available at runtime, means when a device is already created
(DeviceRuntimeParameterX) which will be e.g. used as audio channel
parameters and MIDI port parameters
* src/linuxsampler.cpp: all registered audio output drivers will be shown
on the console on startup
* src/network: implemented configuration of audio output devices via LSCP

CreateMidiInputDevice())
* src/network/lscpserver.cpp: implemented LSCP command
'SET CHANNEL MIDI_INPUT_CHANNEL'
* src/Sampler.h: moved enums 'audio_output_type_t', 'midi_input_type_t'
and 'engine_type_t' into the respective base classes
('AudioOutputDevice', 'MidiInputDevice', 'Engine')

* src/common/Thread.cpp: method StartThread() now blocks until thread
actually runs, mlockall() will only be applied for realtime threads
* libtoolized liblinuxsampler
* initiated automatic unit tests against the LinuxSampler codebase
(see src/testcases): already added a couple of tests for the Thread and
Mutex classes, you have to explicitly compile the unit tests by running
'make testcases' (you need to have cppunit installed though) and then you
can run the console version of the test runner by calling
'src/testcases/linuxsamplertest'
* src/Sampler.h: added API documentation

* 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
