Add libswresample. Similar to libswscale this does resampling and format convertion, just for audio instead of video. changing sampling rate, sample formats, channel layouts and sample packing all in one with a very simple public interface. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

swr: split out DSP functions. DSP bits of swri_resample go into their own mini-DSP functions; DSP init goes from a per-call branch in multiple_resample to a proper DSP init routine; x86 bits go into x86/; swri_resample() moves out of resample_template.c into resample.c because it's independent of DSP code or sample type; multiple_resample() is simplified.

Makefile: Redo duplicating object files in shared builds In case of shared builds, some object files containing tables are currently duplicated into other libraries: log2_tab.c, golomb.c, reverse.c. The check for whether this is duplicated is simply whether CONFIG_SHARED is true. Yet this is crude: E.g. libavdevice includes reverse.c for shared builds, but only needs it for the decklink input device, which given that decklink is not enabled by default will be unused in most libavdevice.so. This commit changes this by making it more explicit about what to duplicate from other libraries. To do this, two new Makefile variables were added: SHLIBOBJS and STLIBOBJS. SHLIBOBJS contains the objects that are duplicated from other libraries in case of shared builds; STLIBOBJS contains stuff that a library has to provide for other libraries in case of static builds. These new variables provide a way to enable/disable with a finer granularity than just whether shared builds are enabled or not. E.g. lavd's Makefile now contains: SHLIBOBJS-$(CONFIG_DECKLINK_INDEV) += reverse.o Another example is provided by the golomb tables. These are provided by lavc for static builds, even if one uses a build configuration that makes only lavf use them. Therefore lavc's Makefile contains STLIBOBJS-$(CONFIG_MXF_MUXER) += golomb.o, whereas lavf's Makefile has a corresponding SHLIBOBJS-$(CONFIG_MXF_MUXER) += golomb_tab.o. E.g. in case the MXF muxer is the only component needing these tables only libavformat.so will contain them for shared builds; currently libavcodec.so does so, too. (There is currently a CONFIG_EXTRA group for golomb. But actually one would need two groups (golomb_avcodec and golomb_avformat) in order to know when and where to include these tables. Therefore this commit uses a Makefile-based approach for this and stops using these groups for the users in libavformat.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

Add Windows resource file support for shared libraries Originally written by James Almer <jamrial@gmail.com> With the following contributions by Timothy Gu <timothygu99@gmail.com> * Use descriptions of libraries from the pkg-config file generation function * Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser) * Use "FFmpeg" for ProductName as MSDN says "name of the product with which the file is distributed" [1]. * Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1]. * Only build the .rc files when --enable-small is not enabled.
