Prior to this on msvc/icl there was no handling of deprecated functions
and the deprecated warning was disabled.
After enabling there are a number of warnings relating to the CRT and
the use of the non-secure versions of several functions. Defining
_CRT_SECURE_NO_WARNINGS silences these warnings.

The benchmark tests the speed of the following algorithms:
MD5, SHA-1, SHA-256, SHA-512, RIPEMD-160, AES-128.
It can optionally be built to perform the same benchmark on
other crypto libraries, for comparison purposes.
The supported libraries are:
- crypto: OpenSSL's libcrypto;
- gcrypt: GnuTLS's libgcrypt;
- tomcrypt: LibTomCrypt
To enable them, use this syntax:
make VERSUS=crypto+gcrypt+tomcrypt tools/crypto_bench
They do not need to have been enabled in configure.

libavutil: Enable the MSVC DLL symbol loading workaround in shared builds as well
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Add one copy of the function into each of the libraries, similarly
to what we do for log2_tab. When using static libs, only one
copy of the file_open.o object file gets included, while when
using shared libraries, each of them get a copy of its own.
This fixes DLL builds with a statically linked C runtime, where
each DLL effectively has got its own instance of the C runtime,
where file descriptors can't be shared across runtimes.
On systems not using msvcrt, the function is not duplicated.
Signed-off-by: Martin Storsjö <martin@martin.st>
This used to only be necessary in static builds (when using the
dynamically linked C runtime), since the _imp prefixed symbols do
exist when linking to the actual DLL. When building testprogs,
however, the current library (e.g. libavutil for some of the testprogs)
is linked statically.
This fixes make fate on DLL builds when using the dynamically
linked C runtime.

Merged-by: Michael Niedermayer <michaelni@gmx.at>
When libavformat was changed to use the new avpriv_open function
in 51eb213d00, this silently bypassed the existing wrapper for
win32. Move the win32 wrapper into libavutil/file.c to make sure
it gets called everywhere (not just in the libavformat case).

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.

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.
