a07c034de7 Gigabeat S: Interrupt enabled bootloader. Miscellaneous integration changes.

1f021af60c Gigabeat S mixer: Make some progress. Get the tick and core sleep working using the AVIC. Redo the startup code to remap from IRAM and not include the lcd driver frambuffer in the remapping (until it can be moved). Clean up LCD driver. For other misc. changes, see the diffs. Now it progresses to ATA init and fails with -11 but without crashing or hanging. Replace all bootloaders.

32a531b09b Do some simplification in switch_thread regarding interrupt enabling which simplifies kernel objects as well. Simply doing unconditional disable/enable should be fine in the firmware. Not sure about the case in the bootloader for all targets and so will evaluate but that should be fine too if everything is masked.

6fac8fcc93 Be sure to register a new mutex owner _before_ waking it. Won't be an issue now but would be with mutex recursion on one used for > 1 core where ownership transfer and cs entry/recursion are allowed to run in parallel (by design). TODO: Add true exchange to wakeup_thread but that's not really important for the time being.

a9b2fb5ee3 Finally full multicore support for PortalPlayer 502x targets with an eye towards the possibility of other types. All SVN targets the low-lag code to speed up blocking operations. Most files are modified here simple due to a name change to actually support a real event object and a param change to create_thread. Add some use of new features but just sit on things for a bit and leave full integration for later. Work will continue on to address size on sensitive targets and simplify things if possible. Any PP target having problems with SWP can easily be changed to sw corelocks with one #define change in config.h though only PP5020 has shown an issue and seems to work without any difficulties.

18e87ff1c0 Stabilize PP5020 targets - tested on H10 5/20GB and iPod Color. Use no interrupts on COP but pulse it through the control interface. Don't mess with LCD clocking during clock changes. Give a reset register a name (DEV_OFF_MASK).

bfb281ff63 Messages queues must be guarded on both ends or else it's a race between detecting a message present and missing a wakeup on thread about to wait. Keeping IRQs from interacting with the scheduler would be preferable but this should do at the moment. Add more detailed panic info regarding blocking violations so we know who. Make panicf function well enough on Gigabeat and PortalPlayer targets. Move the core sleep instructions into a CPU-specific inline to keep thing organized.

165f62d0cd Fix a hole in the scheduler where collisions between waking blocked threads in mutexes with interrupts waking blocked threads in message queues can occur. Queue posts will put the threads on a separate list that is then added to the running list with IRQs disabled on the next task switch or CPU wakeup. Basically no overhead for other operations. Seems a likely cause of my occasional observation of the backlight fade causing playback threads to stop running and a recently reported blocking violation upon USB plugging. Time will tell but banging the backlight on and off frequently hasn't hiccuped again for me on H120.

6d87513aa2 In reponse to a report of a blocking violation, give sync queues a going over and catch any old, obscure leftover issues. A couple spots needed interrupt stopage where there could be confict if an IRQ post wakes a waiting thread because the queue is overflowing. There does appear to be an issue with wakeup_thread, interrupts and running list modification in general.

2370998a87 Disable bootloader messages in the H10 and Sansa bootloaders unless the PLAY (on H10) or RIGHT (on Sansa) button is being held. Messages are still displayed if an error occurs. This has already been implemented for iPod bootloaders, but still needs implementing for the other bootloaders.

dee43ece20 Put an end to priority inversion in the ata driver. Gave up trying to have fully atomic dual use mutexes so just replaced the ata driver locking with spins. Maybe I'll have better luck later. Things should run smoothly with database updates and such happening in the background.

82f9056988 Dual core support for PP502x players (iPod G4 and later, iriver h10, Sansa - iPod G3 will be coming soon.) This allows threads to be run on either core provided that all communications between the cores is done using uncached memory. There should be no significant change in battery life from doing this. Documentation (on the RockboxKernel wiki page) will follow shortly.

8a82892e52 Thread API enhancements. 
1) block_thread -> block_thread + block_thread_w_tmo -- this call was always used in distinct ways so having one call with a conditional was ugly.
2) enhance Slasheri's scheduler controlled boost concept.  now any thread may trigger a boost which will last until that thread next sleeps.

a85044bf9e New scheduler, with priorities for swcodec platforms. Frequent task
