Kacper Michajłow dea75789c3 avutil/file: add av_file_map_shared() and av_file_unmap_shared() 
av_file_map() maps a private copy of a file by name. Code that shares a
file between processes needs the opposite, a writable mapping backed by
the file, of a descriptor it opened itself, that grows with the file.
Provide it with mmap() on POSIX and with a file mapping object on
Windows, which also extends the file to the requested size.
