Use the DLGSUP logging category for GSUP.
Bump the required version of libosmocore to 0.9.5 to benefit from the DLGSUP
logging category fix in core/logging.[hc].

Todo: we're using a "Library" logging category, which is not really what the
library category was intended for. Instead, the GSUP client should probably be
given a logging category like DVLR or DGPRS in its initialization API.

This is in preparation for moving gsup to libcommon, which is in turn
preparation for libvlr.

Make sure everything is named gsup_client_ / GSUP_CLIENT_.
Rename static gsup_client_send() to client_send() to avoid clash with public
gprs_gsup_client_send() being renamed to gsup_client_send().
This is in preparation for moving gsup to libcommon, which is in turn
preparation for libvlr. libvlr and osmo-sgsn will use the same GSUP client
code. A number of patches will follow up on this, also for the the OAP client.
