Once all targets are converted we should probably remove all traces of it entirely.

FIQ/IRQ handlers can't be built with -mthumb, and the thumb case was
buggy anyway (spotted by jhMikeS) : pc offset hadn't been adjusted

When building with eabi gcc, 2 variables are assigned the same register
This might be a bug in the constraints, but it's just simpler to use C,
even at the cost of 1 cycle per loop

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

preventing the DMA callback to advance in the recording buffer is not
enough in pcm_rec_dma_get_peak_buffer()
we need to prevent it interrupting us while we are copying the left
channel data into the right channel

Fix panics when deleting large files from µSD

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.

Enable support for the "force" mode of USB charging. This should work on Gigabeat S and Nano2g (and any other future target which has a RB usb stack and supports charging) - if a host connection is not detected within 10 seconds of USB insertion, assume that the connected device is an AC charger and charge anyway, if the user has specified "force" as the mode.

1) "Charge during USB connection" option is now tristate: off/on/force. Currently "force" behaves just like "on", but in future it will allow charging even when it was not possible to positively identify a charger.
2) The H300 code has been adjusted to use the new system but there should be no functional differences, it already had the USB charging option and its USB/charging support is hardware controlled.
3) The Gigabeat S code has been adjusted to use the new system: the player now has the USB charging option, which wasn't previously available. The player will only charge at full speed when allowed to do so by a working USB host, so USB AC adapters won't work very well; however, they didn't work before either, so this is not a change in functionality.
4) The iPod Nano 2G code has been adjusted to use the new system: it already had the USB charging option. Using a USB AC adapter won't charge at full speed any more (it did before) - the old implementation was equivalent to the not-yet-implemented "force" option in the new system.
No other target should be affected. Support for the "force" mode and support for at least some other iPod models will come in a future commit :)
