8696e51baf lavu/opt: add AV_OPT_TYPE_CHANNEL_LAYOUT and handler functions 
The new type is compatible with AV_OPT_TYPE_INT64, but allows to specify
channel layouts using the format accepted by av_get_channel_layout().

Stefano Sabatini
d96e377c39 lavu/channel_layout: change av_get_channel_layout() behavior at the next bump 
The new syntax is preferred since it allows backward syntax compatibility
with libswr when switching to the new option handling code with
AV_OPT_TYPE_CHANNEL_LAYOUT.

With the new parser the string:
1234

is interpreted as a channel layout mask, rather than as a number of
channels, and thus it's compatible with the current way to set a channel
layout as an integer (e.g. for the icl and ocl options) making use of
integer option values.

ff_get_channel_layout() with compat=0 will be used in the
AV_OPT_TYPE_CHANNEL handler code.

The user is encouraged to switch to the new forward compatible syntax,
which requires to put a trailing "c" when specifying a layout as a number
of channels.

3e2fa991db x86inc: remove misaligned cpu flag 
Prevents a crash if the misaligned exception mask bit is
cleared for some reason.

Misaligned SSE functions are only used on AMD Phenom CPUs
and the benefit is miniscule. They also require modifying
the MXCSR control register and by removing those functions
we can get rid of that complexity altogether.

25cb0c1a1e x86inc: activate REP_RET automatically 
Now RET checks whether it immediately follows a branch, so the
programmer dosen't have to keep track of that condition. REP_RET
is still needed manually when it's a branch target, but that's
much rarer.

The implementation involves lots of spurious labels, but that's OK
because we strip them.

09f2581dc5 msvc/icl: Use __declspec(deprecated) 
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.

d5b58f678d tools: add benchmark for crypto functions. 
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.

e743e7ae6e libavutil: Make avpriv_open a library-internal function on msvcrt 
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.

33237123c8 libavutil: Enable the MSVC DLL symbol loading workaround in shared builds as well 
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.

dfc6b5c814 file: Move win32 utf8->wchar open wrapper to libavutil 
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).

This makes sure that non-ascii file names gets opened properly
(where file names internally are stored as utf8, but they get
converted to wchar_t and opened with _wsopen).
