The meta data of PGLZ symbolized by PGLZ_Header is removed, to make the compression and decompression code independent on the backend-only varlena facility. PGLZ_Header is being used to store some meta data related to the data being compressed like the raw length of the uncompressed record or some varlena-related data, making it unpluggable once PGLZ is stored in src/common as it contains some backend-only code paths with the management of varlena structures. The APIs of PGLZ are reworked at the same time to do only compression and decompression of buffers without the meta-data layer, simplifying its use for a more general usage. On-disk format is preserved as well, so there is no incompatibility with previous major versions of PostgreSQL for TOAST entries. Exposing compression and decompression APIs of pglz makes possible its use by extensions and contrib modules. Especially this commit is required for upcoming WAL compression feature so that the WAL reader facility can decompress the WAL data by using pglz_decompress. Michael Paquier, reviewed by me.
