b7a8935dff iPod 3G: Implement wheel acceleration and repeats. Chosen settings feel pretty decent but can be tweaked.

45c7498f59 FS#11335 by me: make ARM assembly functions thumb-friendly 
We can't pop into pc on ARMv4t when using thumb: the T bit won't be
modified if we are returning to a thumb function
Code running on ARMv4t should use the new ldrpc / ldmpc macros instead
of ldr pc, [sp], #4 and ldm(cond) sp!, {regs, pc}
No modification on pure ARM builds and ARMv5+

Note: USE_THUMB is currently never defined, no targets can currently be
built with -mthumb, see FS#6734

4a2cab6aa1 USB charging support for iPods. 
This adds proper full speed charging support for iPod 4G, Color, Mini 1G, Mini 2G, Nano 1G, and Video. Nano 2G already has support, so now all ipods charge (except 1G-3G whose hardware doesn't support USB charging).

USB charging defaults to on, but will only charge at full speed from a USB host. To charge from an AC charger, you need to set the USB charging mode to "force". It may be possible to detect AC chargers in a future version, at least on some models.

7a1aca46a3 Smaller & faster grey blitting on greyscale ipods, based on an idea by Mike Sevakis. ISR speedup on all greyscale iPods except Mini 2nd Gen is ~10%. No speedup on the latter, because the serial transfer is the limiting factor.

2960052d28 Increaase default ipod 3g contrast, to a value between the last two. 
It seems there is some significant variance between different greyscale ipods of the same model, so it's unlikely that *any* value will be great for everyone. I'm hoping that this is just high enough that the lightest screens aren't totally blank, but not dark enough that the darkest screens are entirely unreadably black ;)

This rather unsatisfactory compromise is to help us get a new bootloader release out (since bootloaders can't have their contrast adjusted) - a real fix would be to detect the LCD type, which the OF appears to be able to do (maybe).

50a6ca39ad Move c/h files implementing/defining standard library stuff into a new libc directory, also standard'ify some parts of the code base (almost entirely #include fixes). 
This is to a) to cleanup firmware/common and firmware/include a bit, but also b) for Rockbox as an application which should use the host system's c library and headers, separating makes it easy to exclude our files from the build.

5b4a84a4ce FS#11149: alternative fix for ipod startup/shutdown issue 
Instead of using the OF's low-battery handler to force a shutdown which appears to have numerous unwanted side effects, just clear the end of IRAM before shutting down which appears to solve the original "ipod sometimes needs hard reset to turn on" issue.

If you experience the "need hard reset" issue after this commit, please let us know. It has been tested on several models but we still don't know for sure what the original problem was. ;)

d4bfc15232 FS#10107: work around the issue on some ipods where after shutdown they do not power on. 
Some ipods do not power on correctly after being shut down and require a hard
reset before they work again. This workaround shuts the device down via the OF
which prevents the problem from occurring. There is a cosmetic effect: the low
battery symbol appears briefly on power of.

Change applies to PP502x ipods: 4G/photo/video/mini1g/mini2g/nano1g

Patch by Boris Gjenero (dreamlayers), manual changes by me.

With this option the user can decide whether to keep the transflective LCD switched on (e.g. during daylight use) or to switch it off (to save power).

58eb784a5d Straighten out some powermanagement stuff. Give target complete control over how power inputs are sensed. Clean SIMULATOR stuff out of target files. Get rid of USB charging option on targets that don't support it or don't implement it yet. Menu string remains to avoid language incompatibility but should be removed on next cleanup for targets not using it (notice in english.lang). global_settings becomes incompatible for some builds and so plugin API version is incremented.

2bbacf89fe Make sure the linker considers crt0*.o before all files specified on the command line by using STARTUP() instead of INPUT() in the .lds. Using INPUT() makes the linker process crt0*.o after all files specified on the command line, making linking fail if there are librockbox.a members which are only referenced by crt0*.o. Remove the hackaround that was needed for building the gigabeat S bootloader before (aka UIE() problem).

05099149f1 Enable nocache sections using the linker. PP5022/4 must use SW_CORELOCK now with shared variables in DRAM (it seems swp(b) is at least partially broken on all PP or I'm doing something very wrong here :\). For core-shared data use SHAREDBSS/DATA_ATTR. NOCACHEBSS/DATA_ATTR is available whether or not single core is forced for static peripheral-DMA buffer allocation without use of the UNCACHED_ADDR macro in code and is likely useful on a non-PP target with a data cache (although not actually enabled in config.h and the .lds's in this commit).

32bd0f8ab1 Greyscale library: Optionally put the greyscale ISR on COP on portalplayertargets (only use with the grey_info structure in IRAM atm\!). This speeds up doom by ~50%, and makes mpegplayer work without stuttering audio on targets using it (measured on iPod 2nd Gen and Mini 2nd Gen). It needs corelocking certain functions in the LCD driver on 1st/2nd Gen.

054447f9e6 Commit FS#8379 by Andree Buschmann. Disables much of the remaining unneeded hardware on PP50xx targets (Ipods, Sansa, H10s, etc) resulting in a large savings in power and consequent increase in battery life. Results vary from target to target and from codec to codec, but we now approach the OF runtime on several PP devices. For now, leave base CPU clock at 30MHz, although further savings is possible with some codecs if clock is reduced. Additionally, fix battery capacity on c200 and use my measurements to improve runtime estimation for Sandisk targets.

6a56c14e17 Greyscale library: Changed the internal data format once more (separated pixel values and phases), allowing for further optimisation of drawing, scrolling etc. * Optimised grey phase blitting in the core reduces CPU load on all architectures, most significantly on coldfire. Previous version was too slow to keep up at 45MHz, leading to unwanted graininess (update frequency was halved). Also fixed screendump on 2bpp targets with vertical pixel packing.

feb5b15e9b All-new greyscale library, replacing the old one. Features: (1) Drawing/updating is faster than the old grayscale lib at full depth. (2) Always 129 shades instead of 2..33 shades. (3) No graininess caused by frequent updates (mpegplayer, doom, ...). (4) Needs less memory than the old grayscale lib at full depth. * The tradeoff is slightly higher CPU load in the ISR (frames are calculated 'live') and an extra function in the core. * Ported all plugins which used the graylib to use the new one. * Some slight optimisations for archos and H1x0 LCD update.
