Add LZ4 compression to pg_dump

Expand pg_dump's compression streaming and file APIs to support the lz4
algorithm. The newly added compress_lz4.{c,h} files cover all the
functionality of the aforementioned APIs. Minor changes were necessary
in various pg_backup_* files, where code for the 'lz4' file suffix has
been added, as well as pg_dump's compression option parsing.
