* Get rid of non-async (ie tick task) mode due to inherent brokenness
* Get rid of nonblock mode; we never write if buffers aren't sufficient
* Move driver init into pcm_open() instead of pcm_init()
* Much better underrun handling
* Better error handling in some situations
* Add in recording functionality
* Use smaller audio buffers to avoid glitching
* Don't start audio buffer with silence
* Allow device name to be overridden by target
Recording portions based on work done by Lorenzo Miori in g#633

* xduoo x3ii/x20: Better line out support

SUPPORTED SERIES:
- NWZ-E450
- NWZ-E460
- NWZ-E470
- NWZ-E580
- NWZ-A10
NOTES:
- bootloader makefile convert an extra font to be installed alongside the bootloader
since sysfont is way too small
- the toolsicon bitmap comes from the Oxygen iconset
- touchscreen driver is untested
TODO:
- implement audio routing driver (pcm is handled by pcm-alsa)
- fix playback: it crashes on illegal instruction in DEBUG builds
- find out why the browser starts at / instead of /contents
- implement radio support
- implement return to OF for usb handling
- calibrate battery curve (NB: of can report a battery level on a 0-5 scale but
probabl don't want to use that ?)
- implement simulator build (we need a nice image of the player)
- figure out if we can detect jack removal
POTENTIAL TODOS:
- try to build a usb serial gadget and gdbserver
