android: Hopefully fix a rare hang of the UI.

Sometimes (and perhaps only on some devices) Android's YesNo dialog
loses focus and is put to the background. Since the native code waits on the
result (which is then impossible to happen) it would become impossible
to further control Rockbox. This is an attempt to fix as I cannot reproduce
the problem on my device(s).

ARMv5 optimized complex multiply function for libopus.

Speeds up decoding of 128k opus files by 1.2MHz on AMSv2. Rounding
error is 1 bit due to KissFFT using a 15 bit shift instead of a 16 bit shift.

Also, change an LDMIA in the armv4 code to LDM as the pointer should not
increment.

Avoid unnecessary HEAD request on uncached file.

If a file is not available in the cache immediately sent a GET request. Using a
HEAD request to retrieve the file timestamp on the server is not necessary and
only creates an unnecessary network request.

Remove support for RFC850 timestamps.

RFC850 timeformat isn't y2k compliant. Furthermore, parsing turned out to be
broken and it doesn't seem supporting the format is necessary anyway.

Fix FS#12391 : Memory corruption on PP502x after commit_discard_idcache()

In commit_discard_idcache(), cache lines were marked as invalid. When
some cache lines are marked as invalid, memory corruption can occur.
This caused instability when using PP502x ATA DMA because of the many
more calls to that function. Here, commit_discard_idcache() is changed
to avoid the problem. Also, the cache is filled after being enabled to
to ensure there are never any cache lines that aren't marked as valid.

Re-enable PP502x ATA DMA

PP502x ATA DMA was disabled in 55fab77 because it caused various
instability on all targets using it. This instability is fixed in
583c948 via FS#12391. Here, ATA DMA is enabled for all PP502x targets
except nano1g and hdd6330. For nano1g, there may be other causes of
instability and more testing is needed. ATA DMA does not work on hdd6330.

PP: Do not use ATA DMA in bootloader

The build of bootloader with HAVE_ATA_DMA fails because of missing
commit_discard_dcache(). This seems to be bigger problem as
bootloader builds don't call  cache_init() also which seems wrong.
but I know too little about the PP platform to judge.
For now use ATA DMA only in regular builds.
