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.

d52f2e4bca Encoders: Add a little dithering with the fractional bit for mono mixdowns so faster shifts can be used again instead of division without introducing their own DC offset into the mixed channels.

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.

3b7d703329 Encoders: Mixdown to mono should round towards zero not -infinity.

80da8b141c FS#6357, patch 1: let iramcopy and bss share the same space in codecs and
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.

aa9ddbd8ba Fixed header calculation goofs that would've affected mono files and little-endian targets. A bit of general cleanup. Time for bed.

0729b928ce Recording: Add AIFF recording to SWCODEC. Note: AIFF playback chokes on sample rates other than 44.1kHz whether recorded or created and saved with an external program. Recorded files will still open in an external editor however.
