I think the assumption is that during playback, the DSP is already running
so it assumes PBE needs to be flushed before it is properly enabled.

mp4 files can have multiple 'mdat' chunks. This is common for
audiobooks, where there is often a secondary mdat containing the
chapter names, but it's also legal to have multiple mdat chunks
for a single logical "track"
This confuses the mp4 metadata parser, which assumes there is
only a single mdat, and always uses the last mdat seen to
determine the "filesize" of the data we're trying to decode.
Work around this by appending each mdat's size to result in the final
"filesize"

GCC 4.9.4 was already used for MIPS and all hosted targets; this enables
it across the board for everything (ie m68k and arm native)
Other changes:
* Use '-Os' as the default optiomization for all targets
(was only disabled for arm native)
* Enable -funit-at-a-time and -Wextra
* Drop all obsolete toolchain patches
* Update ARM multilib/exception patch
* Bump toolchain libs (gmp, mpfr, mpc) to recommended versions, and
add 'isl' to enable better optimization & vectorization opportunities.
(Will revisit optimization for the codecs and plugins at a later date)
Confirmed working:
* armv4t (ipodmini2g and many other PP502x targets)
* arm >= v5 (sansaclipplus, ipod6g, ipodnano2g, sansafuzeplus)
* m68k (ihp100)

Note: I left behind lcd_bitmap in features.txt, because removing it

'swcodec' is now always set (and recording_swcodec for recording-capable
units) in feature.txt so the manual and language strings don't need to
all be fixed up.

By moving three structures to the heap. None are in the hot decode
loop, instead having to do with file sync / header state.
Has neglible impact on performance (within measurement noise) on Clip+,
Rocker, and Xduoo X3.
On PP5022 (ipodmini2g) performance drops from 138.66% to 138.22% realtime.
(0.3%)
Unknown effect on Coldfire which lacks D$.
Stack savings are pretty significant especially on lowmem devices.

apparently we should be doing this anyway
mark4o> The packets overlap and may reuse state set by other recent packets,
so if you seek to a different position,
resetting the state helps to ensure that the subsequent
packets won't use the state set by the unrelated packets
that were processed before the seek.

opus requires the comment header to be a valid file our codec attemps to skip the comment data
in order to reduce the ram allocated originally it caused files with large album art to skip
the beginning of tracks my first attempt at fixing this then caused files with low bitrates
to do the same while fixing files with large album art
This patch should fix both although the initial start might be a bit slower but
this shouldn't cause too much of an issue

knocks off about .5 second from decode time not a big change but might help a bit on

On Classic, IRAM1 (second 128Kb of a total of 256KB available IRAM) is
slower than DRAM. Codecs that actually are using regions of IRAM1 runs
faster when DRAM is used, so IRAM1 is disabled and only IRAM0 remains
enabled: 48KB for core and 80KB for codecs/plugins.
The next test_codec results shows how decode time is decreased:
file boosted unboosted
*.ra ~1.5% ~0.5%
*.mpc ~21% ~4.5%
*.ogg ~0.5% ~0%
nero_he*.m4a ~8% ~1%
nero*.m4a ~25% ~7%
wmapro*.wma ~4.5% ~0%
wma*.wma ~25% ~7%
In addition there is a small power save when IRAM1 HW is disabled.

Just use long so the compiler potentially doesn't complain about
use of other values not in the enum. It's also the type used
around the system for event ids.
Increase min codec API version.

Most importantly is surround shouldn't operate in mono mode. Have it

Other changes to better handle buffer allocation failure.

On Windows 64-bit, the size of long is 32-bit, thus any pointer to long cast is
not valid. In any case, one should use intptr_t and ptrdiff_t when casting
to integers. This commit attempts to fix all instances reported by GCC.
When relevant, I replaced code by the macros PTR_ADD, ALIGN_UP from system.h
