The buflib memory allocator is handle based and can free and
compact, move or resize memory on demand. This allows to effeciently
allocate memory dynamically without an MMU, by avoiding fragmentation
through memory compaction.
This patch adds the buflib library to the core, along with
convinience wrappers to omit the context parameter. Compaction is
not yet enabled, but will be in a later patch. Therefore, this acts as a
replacement for buffer_alloc/buffer_get_buffer() with the benifit of a debug
menu.
See buflib.h for some API documentation.

Also set up a callback for the battery capacity setting (for all players) so changes take effect without having to reboot.

bsearch() is a general purpose binary search function for arrays.
It's supposedly faster than looping over arrays.
The array needs to be sorted in ascending order under the provided
comparison function. If the key and array element are of the same kind,
then the same compare function can be used for qsort() and bsearch().
Code taken from glibc.

Since the bootloader currently always fails at storage point (unimplemented), always enter touchpad debug screen and power off which pressing power button.

I tried to move the #ifdefs and the code
in firmware/powermgmt.c around and it was still
a big mess for hosted applications (RaaA/sim builds).
Create our own "power" thread as recently discussed on IRC.
Fixes the sleep timer for RaaA.

This replaces SDL threads with real cooperative threads, which are less cpu intensive and allow priority scheduling.
The backend for context switching is dependant on the host (sigaltstack/longjmp on Unix, Fibers on Windows).
configure has options to force or disallow SDL threads.

Adds Nokia N900, N810 and N800 support.
Features:
- Introduce maemo specific platform defines
- Play audio in silent mode
- Stop playback on incoming calls
- Battery level readout
- Bluetooth headset support
- Save CPU by disabling screen updates if the display
is off or the app doesn't have input focus
- N900: GStreamer audio backend
Kudos to kugel for the code review.

Major known issues:
- No bootloader yet
- No support for the first-generation 160GB CE-ATA hard disk drive yet
- Audio playback is slow, only FLAC seems to reach realtime

* For some reason, the polling methid is much more inefficient than I thought. According to htop it caused up to 15% CPU load on some phones (e.g. Galaxy S).
The event based causes no CPU load.
Rockbox' idle CPU load is now back to 0%, while it was previously dominated by polling the call state.
* Also stop on outgoing calls (no need to explicitely pause for making a call anymore).
* Factor out the detection mechanism to separate files.

Instead implement a bit of battery monitoring. Currently it only fetches the battery level (in %) every 30s,
but it could do more like battery status, charger connected, voltage...
Theoretically, we could also exit/quit after some time of inactivity too
(perhaps not a bad idea since Rockbox puts a slight but still non-zero CPU load even if doing nothing).
Ironically, Rockbox is now the only way to get the exact battery level (at least I haven't found anything yet) on my phone :-)

Use host's functions for file i/o directly (open(), close() ,etc.), not the sim_* variants.
Some dir functions need to be wrapped still because we need to cache the parents dir's path (host's dirent doesn't let us know).
For the same reason (incompatibility) with host's dirent) detach some members from Rockbox' dirent struct and put it into an extra one,
the values can be retrieved via the new dir_get_info().
Get rid of the sim_ prefix for sleep as well and change the signature to unix sleep().

It's a used by codec/plugin loading and vastly reduces code duplication. It's also a step forward in getting rid of libuisimulator in the application ports.
Apparently sh needs linker symbols prefixed with _ even if they're referenced without from C code.
