2acc0ac542 Updated our source code header to explicitly mention that we are GPL v2 or 
later. We still need to hunt down snippets used that are not. 1324 modified

8e6e290a95 Factor first order shelving filter code out for easier reuse and replace the crossfeed filter with it. Crossfeed _should_ still sound the same, so please do tell if it doesn't.

a7fabf0741 Add software based bass/treble controls for targets which have no such functionality in hardware (currently only X5). They can also be used on any other SWCODEC target by adding #define HAVE_SW_TONE_CONTROLS in the relevant config-*.h file. Also remove some now unneeded zero checks when using get_replaygain_int(). Comments on sound quality are welcome as some parameters can still be fine-tuned.

48b4ac3745 Two more bits of precision for shelving EQ filters and some comment updates. Tested quite thoroughly, but as always with audio related commits: mind your ears.

8238b49c74 New crossfeed complete with no volume reducing bugs. Feedback on all the 
new options is appreciated. Thanks to Dan Everton for the settings/GUI
code.

c00ec11598 Further 64 bit related fixes. EQ should now work in AMD64 sim.

ea4ccb5aba Samples should always be 32 bit on all platforms, so change most 
occurences of long to int32_t to enable working sounds also on 64 bit
sims. Note that some codecs (MP3 and Wavpack) still have other 64
bit related problems.

7df51ada07 Changed meaning of shift parameter to include the EMAC implicit shift 
factor. ARM version is already fixed.

making that user interface!
