libpqtypes - libpqtypes: Added support for PQspecPrepare.

Log Message:
-----------
Added support for PQspecPrepare. This required centralizing spec format parsing code into spec.c, so several functions like putf and getf can make use of it. Added a man page for the new function, a regression test and updated the change log.
