On recent android versions, /proc/self/auxw is unreadable
(unless the process is running running under the shell uid or
in debuggable mode, which makes it hard to notice). See
http://b.android.com/43055 and
https://android-review.googlesource.com/51271 for more information
about the issue.
This makes sure e.g. neon optimizations are enabled at runtime in
android apps even when built in release mode, if configured to
use the runtime detection.

Memory passed to av_realloc must come from malloc,
calloc or realloc, and not e.g. memalign. realloc(3):
The realloc() function changes the size of the memory block pointed to
by ptr to size bytes. (...) Unless ptr is NULL, it must have been
returned by an earlier call to malloc(), calloc() or realloc().
The issue has been found by debugallocation, a part of google-perftools:
http://code.google.com/p/gperftools/ .
This makes fate pass when using LD_PRELOAD-ed debugallocation.

Now, nellymoserenc and aacenc no longer depends on dsputil. Independent
of this patch, wmaprodec also does not depend on dsputil, so I removed

The function is known to be missing in at least one target (MSVC).

Merged-by: Michael Niedermayer <michaelni@gmx.at>
Use the i64 field rather than the string value. Using a string to set a
default sample/pixel format is weird, also the new interface is more
consistent with the rest of the API.
This is technically an API break, but hopefully there are no applications
using this feature outside of FFmpeg. In order to save backward
compatibility with mixed libraries in case libavutil is updated but not
the other libraries, some ifdeffery hacks are added.
Note that the version check is only performed when class->version != 0,
since if it is not defined then we assume that no version was defined and
the class is not affected by the change.
We will luckily get rid of the hack at the next major bump.
The existence of MapViewOfFile isn't linked to the existence of
io.h.
Not all versions of windows have MapViewOfFile (in particular,
Windows Phone 8 and the "metro" windows 8 API subset don't),
while they still have io.h (and need it for open/read/close).

Make the functions av_samples_fill_arrays, av_samples_alloc, and
avcodec_fill_audio_frame return a buffer size rather than 0 in case of
success. This will be enabled at the next libavutil major bump, in order
to preserve backward compatibility.
Returning the size allows to simplify the code, avoiding a few function
calls.
Preventing the use of discouraged or 'insecure' external functions
through defines in an internal header is not a good solution. The
header is not guaranteed to be included universally which makes
overlooking bad use of said functions during review more likely.
There are cases were those functions either are the most straight
forward solution or even have to be used. Using malloc or free is
required if the allocation or release is done by other libraries.
- Add special cases for offsets of 2, 3, or 4 bytes. This means the
offset is always >4 in the generic case, allowing 32-bit copies to
be used there.
- Don't use memcpy() for sizes less than 16 bytes.
