add DLCX command statistics to osmo-mgw

Add a counter group for DLCX commands. The group contains counters for
successful connection processing as well as various error conditions.
This provides a quick overview of DLCX failures on each trunk throughout
the lifetime of the osmo-mgw process.

The counters are displayed by 'show mgcp stats' and 'show rate-counters'

While here, rename MGCP_MDCX_FAIL_DEFERRED_BY_POLICY to
MGCP_MDCX_DEFERRED_BY_POLICY; we have decided that deferred connections
aren't failures, and this keeps names used by DLCX and MDCX in sync.

Also remove some allocation failure checks with OSMO_ASSERT(); such
checks aren't en vogue anymore.
