libavcodec currently exports four avpriv symbols that deal with PixelFormatTags: avpriv_get_raw_pix_fmt_tags, avpriv_find_pix_fmt, avpriv_pix_fmt_bps_avi and avpriv_pix_fmt_bps_mov. The latter two are lists of PixelFormatTags, the former returns such a list and the second searches a list for a pixel format that matches a given fourcc; only one of the aforementioned three lists is ever searched. Yet for avpriv_pix_fmt_bps_avi, avpriv_pix_fmt_bps_mov and avpriv_find_pix_fmt the overhead of exporting these functions actually exceeds the size of said objects (at least for ELF; the following numbers are for x64 Ubuntu 20.10): The code size of avpriv_find_pix_fmt is small (GCC 10.2 37B, Clang 11 41B), yet exporting it adds a 20B string for the name alone to the exporting as well as to each importing library; there is more: Four bytes in the exporting libraries .gnu.hash; two bytes each for the exporting as well as each importing libraries .gnu.version; 24B in the exporting as well as each importing libraries .dynsym; 16B+24B for an entry in .plt as well as the accompanying relocation entry in .rela.plt for each importing library. The overhead for the lists is similar: The strings are 23B and the .plt+.rela.plt pair is replaced by 8B+24B for an entry in .got and a relocation entry in .rela.dyn. These lists have a size of 80 resp. 72 bytes. Yet for ff_raw_pix_fmt_tags, exporting it is advantageous compared to duplicating it into libavformat and potentially libavdevice. Therefore this commit replaces all library uses of the four symbols with a single function that is exported for shared builds. It has an enum parameter to choose the desired list besides the parameter for the fourcc. New lists can be supported with new enum values. Unfortunately, avpriv_get_raw_pix_fmt_tags could not be removed, as the fourcc2pixfmt tool uses the table of raw pix fmts. No other user of this function remains.
