Gen_fmgrtab.pl creates a new file fmgrprotos.h, which contains
prototypes for all functions registered in pg_proc.h. This avoids
having to manually maintain these prototypes across a random variety of
header files. It also automatically enforces a correct function
signature, and since there are warnings about missing prototypes, it
will detect functions that are defined but not registered in
pg_proc.h (or otherwise used).

This is needed to allow ORDER BY, DISTINCT, etc to work as expected for
pg_lsn values.
We had previously decided to put this off for 9.5, but in view of commit
eeca4cd35e there's no reason to avoid a
catversion bump for 9.4beta2, and this does make a pretty significant
usability difference for pg_lsn.
Michael Paquier, with fixes from Andres Freund and Tom Lane
Change input function error messages to be more consistent with what is
done elsewhere. Remove a bunch of redundant type casts, so that the
compiler will warn us if we screw up. Don't pass LSNs by value on
platforms where a Datum is only 32 bytes, per buildfarm. Move macros
for packing and unpacking LSNs to pg_lsn.h so that we can include
access/xlogdefs.h, to avoid an unsatisfied dependency on XLogRecPtr.
