Introduce a generic pg_dump compression API

Browse Source 
Switch pg_dump to use the Compression API, implemented by bf9aa490db.

The CompressFileHandle replaces the cfp* family of functions with a
struct of callbacks for accessing (compressed) files. This allows adding
new compression methods simply by introducing a new struct instance with
appropriate implementation of the callbacks.

Archives compressed using custom compression methods store an identifier
of the compression algorithm in their header instead of the compression
level. The header version is bumped.
