pgAdmin III commit: Better detection of PQconninfoParse function

Commit: http://git.postgresql.org/gitweb?p=pgadmin3.git;a=commitdiff;h=d927b4ebe4cc0e3317357f3cd9552df634ea1682

Log Message
-----------
Better detection of PQconninfoParse function

PQconninfoParse is only used if the built was done against an 8.4+ libpq.
A user can still compile pgAdmin with an older library but at the cost that
the application_name connection parameter won't be set when connecting to any
PostgreSQL releases (even 9.0+).
