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

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 :)

(forward port of r26481 + cosmetics)
This lead to freezes under various conditons (bug report: FS#11267)
Battery life is almost not (if at all) affected:
- between 4 and 8 minutes less runtime for fuzev1
- 9 minutes less runtime for c200v2 (2 minutes difference on a 2 hours run)
Additional verifications of the runtime (including on other models) wouldn't hurt

this removes workaround for spurious interrupts added in r26316
side effect: make keyclicks work correctly when used intensively (with
the scrollwheel for example), the clicks should be inserted fast enough
for the PCM fifo to not become empty.
PL190 can cause spurious interrupts if an interrupt is triggered by a
peripheral shortly before the interrupt for this peripheral is cleared
from VIC registers.
As an effect we should only write in VIC_INT_EN_CLEAR after having
disabled the source of the interrupt in the peripheral.

Skipped the specifiers for octal, (u)int_leastN_t, (u)int_fastN_t and
(u)intmax_t as we don't use them in rockbox
Specifiers use the types specified in stdint.h
Specifiers for short (16 bits) and char (8 bits) use the int specifier,
our format.c doesn't know about 'h' and 'hh'
