Add the --norc option to bypass configuration files. When parsing lines
in the configuration file, disable paramter matching if we're not in the
section that match the current file's MD5 sum.

Add this option from xmp 3.5.0 to handle bugs in Protracker 2.x set sample
offset command.

I've downloaded and installed the xmp-snapshot from Sun, Dec 20 today.
Don't know just how good the protrack-emulation is planned to get, but
there's a bug in the interpretation of Protracker's handling of effect 0x09
(SetSampleOffset), that causes some MODs to play incorrectly.
Original Protracker-source has some bug in handling effect 09, in that
the sample offset given in the effect byte is added +twice+ to the current
sample offset, once before playing this instrument (as is expected), and
once again after this instrument has been played! So, if on the same channel
the same instrument is played again without resetting the instrument's
parameters (eg. when just a note period is specified, but not the instrument
number again? or the other way round? :), the offset is twice as high
as one would expect.
This can be heard very easy eg. in the (very popular) song "No Mercy" by
Alf/VTL, Position #2-#3 in the sequence.

This option passes XMP_FLAGS_FIXLOOP to the library. See README.fixloop
in the library documentation for more details.

Certain modules need specific adjustments to play correctly. It's not
possible to automatically detect these modules, so a module-specific
configuration file was added. Adjustments include: workaround for
module conversion errors, differences between protracker versions,
and custom replay parameters for specific modules.

Use the --vblank command-line option to force vblank-based timing instead
of CIA tempo setting. Needed by some modules such as Klisje paa klisje.
Needs new timing API.

Configuration file support was removed during the library conversion.
Re-add it in the player front-end, but remove module-specific config
file for now.

Make naming consistent for API calls, so:
xmp_player_start -> xmp_start_player
xmp_player_end -> xmp_end_player
xmp_player_get_info -> xmp_get_frame_info
xmp_mixer_set -> xmp_set_mixer
xmp_mixer_get -> xmp_get_mixer
Also renamed:
xmp_module_info -> xmp_frame_info
because its information is mostly about frame-specific data.

The previous stable release of the player (xmp 3.5.0) had option -r
to reverse stereo channels. This option was temporarily removed during
libification to simplify the code base.
Reverse channels option was reimplemented by simply accepting negative
mixing parameters.

Port the configuration file reader from xmp 3.5 to 4.0. Module-specific
configuration still not ported.

Default interpolation algorithm set to cubic spline. Also remove direct
option --nearest/-n to set nearest neighbor interpolation.

Follow Mirko Buffoni's advice to add extra mixers with better interpolation
algorithms. Start adding cubic spline based on Storlek's implementation, still
need to fix sample allocation values to prevent violations when reading
the -1 PCM data.

Add DSP flags to mixer and generalize the existing lowpass filter as a
DSP effect. Reverb and chorus effects (used in e.g. IMF) can be added
to the list later.

- change XMP_FORMAT_* to XMP_MIX_* because they're actually mixer parameters
and not only sample format flags
- briefly document the essential parts of the API in README
- update the player application to use the new API

Use number of samples in loop otherwise Samples are garbled (you copy-pasted
mod->ins as sample numbers) (fixed by Mirko Buffoni)
