Add an API to get a list of compressed-file extensions, and use it.

Move all the compressed-file type stuff to wiretap/file_wrappers.c.

Rename wtap_compressed_file_extension() to
wtap_compression_type_extension() for consistency with the other
compression-type-extension routine names.

Move the declarations of the compression-type-extension routines in the
header file.

wtap_compression_type_extension() now returns NULL for
WTAP_UNCOMPRESSED; there's no need to special-case it.

Get rid of the now-unused wtap_compression_type_supported() and
WTAP_NUM_COMPRESSION_TYPES.
