Centralize PostgreSQL page header data structures.

Browse Source 
These data structures were copied a few places (but only once in the core code) so put them in a place where everyone can use them.

To do this create a new file, static.auto.h, to contain data types and macros that have stayed the same through all the versions of PostgreSQL that we support.  This allows us to have single, non-versioned set of headers and code for stable data structures like page headers.

Migrate a few types from version.auto.h that are required for page header structures and pull the remaining types from PostgreSQL directly.

We had previously renamed xlog to wal so update those where required since we won't be modifying the PostgreSQL names anymore.
