471d881979 ARM targets: Making a few functions non-static allows us to get rid of -ffunction-sections, significantly decreasing binary size and making things run a bit faster because static functions are no longer long_call.

97f369a587 SWCODEC: Annoying neatness update. Use intptr_t for codec_configure_callback and dsp_configure and stop all the silly type casting of intergral types to pointers to set dsp configuration and watermarks. Shouldn't have any effect on already compiled codecs at all. Will fix any important patches in the tracker so they compile.

* Fix name of Speex library in codecs Makefile.

aba6ca0881 Fix resampling clicking as much as possible at the moment. 1) Upsampling clicked because of size inaccuracies returned by DSP. Fix by simplifying audio system to use per-channel sample count from codec to pcm buffer. 2) Downsampling affected by 1) and was often starting passed the end of the data when not enough was available to generate an output sample. Fix by clamping input range to last sample in buffer and using the last sample value in the buffer. A perfect fix will require a double buffering scheme on the resampler to sufficient data during small data transients on both ends at all times of the down ratio on input and the up ratio on output.

df0dc2262e FS#6096. Recording on PortalPlayer targets (H10, iPod Video, iPod 4g, iPod Color, iPod Nano). 
* Fix failed compile of enc_config.c when HAVE_MPEG2_SAMPR is not defined.
* Fix bug in AIFF encoder header creation on little endian targets.
* Add recording screen keymaps for H10 and iPod.
* Move pcm_playback PP specific code to target tree.
* Add recording code to wmcodec drivers.
* Add pcm_record code.

Some problems still remain:
* Playback doesn't work after recording until Rockbox is restarted.
* Gain control not implemented.
* Only 16-bit/44KHz for now. The hardware should be capable of up to 24-bit/96KHz.
* Line-in recording not tested on H10.

plugins. Currently, in case of plugins using IRAM bss is cleared twice,
once in the loader, once in PLUGIN_IRAM_INIT. For codecs, bss is cleared only
during codec initialization. Also, removed double variables in codecs
storing a pointer to codec_api.
