* x86inc: Set ELF hidden visibility for global constantsHenrik Gramner2013-10-07

* x86inc: activate REP_RET automaticallyLoren Merritt2013-10-07
| | | | | | | | | | | | 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.

* msvc/icl: Use __declspec(deprecated)Alex Smith2013-09-20
| | | | | | | | | | | 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.

* libavutil: Make avpriv_open a library-internal function on msvcrtMartin Storsjö2013-08-10
| | | | | | | | | | | | | | | 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>

* libavutil: Enable the MSVC DLL symbol loading workaround in shared builds as ↵Martin Storsjö2013-08-10
| | | | | | | | | | | | | | | 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.

* file: Move win32 utf8->wchar open wrapper to libavutilMartin Storsjö2013-08-08
| | | | | | | | | | | | | When libavformat was changed to use the new avpriv_open function in 51eb213d001, 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).

* avopt: Check whether the object actually has got an AVClassMartin Storsjö2013-07-31
| | | | | | | | | | AVIOContext has got an av_class member that only gets set if opening the context using avio_open2, but not if allocating a custom IO context. A caller that wants to read AVOptions from an AVIOContext (recursively using AV_OPT_SEARCH_CHILDREN) may not know if the AVIOContext actually has got a class set or not.
