Use an extension to denote vendorized code.

Vendorized code is copied from another project when a library is not available and a git subproject won't work. Currently all the vendorized code is copied from PostgreSQL but it makes sense to have a more general mechanism for indicating vendorized code.

The .vendor extension will be used to denote vendorized code in the same way that .auto is used to denote auto-generated code.

 evolve over time, this seems to be the easiest way to extract information from them.
 
 These macros should be kept as simple as possible, with most of the logic contained in postgres/interface.c.
 
 Each version of PostgreSQL will need a vXXX.c file to contain the version-specific functions created by these macros.
