Allow access to headers from INVITE

This adds a sip profile parameter parse-all-invite-headers that when
set parses all headers from an INVITE into channel variables.  The
headers are converted to lowercase, underscores are replaced with
dashes, and the result is prefixed with sip_i_.  Headers than exist
more than once are set as arrays.

FS-5512 --resolve ; clean up PostgreSQL libpq client detection in configure

Clean up the libpq autodection and make sure it functionswith both pg_config and pkg-config.

if you are installing into a non-FHS standard location such as what happens with RPMs from the Postgres yum repo, you will need to make sure pkg-config can fild the libpq.pc file.
example: export PKG_CONFIG_PATH=/usr/pgsql-9.3/lib/pkgconfig

you may also want to make sure your path can find pg_config
example: export PATH=/usr/pgsql-9.3/bin:$PATH
