Previously any esl_connect_timeout() failures would not return to the calling application the reason for the failure.
This commit now allows for calling applications to know why the connection attempt fails, but it is now the calling
applications responsiblity to call esl_disconnect() on the esl handle after the failure. Failing to call disconnect after
a failed connection attempt would result in memory being leaked.

This looks like a copy/paste error.

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

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.

When an endpoint registers to us we internally mark the expiration as
some seconds longer than the actual registration.  Previously this
value was fixed at 60 seconds.

Some people need this value to be shorter so they can meet their SLA
by taking a different action when a device doesn't re-register when
expected.

This commit adds a SIP profile parameter sip-expires-late-margin which
allows setting the margin value we apply here.
