It's needed for authentication (not used by the mongodb destination at
the moment, but I plan to add authentication support later), and later
on for GridFS (but that's irrelevant for syslog-ng). I suppose I can add
a little compat layer that'd fall back to OpenSSL if glib is too old.

It's only some MD5 stuff I use from 2.16. For 0.1.3 (ETA: July 22nd),
I'll drop back to requiring glib >= 2.12 only, and using either
GChecksum from glib >= 2.16 if present, or OpenSSL otherwise.

All in all, it's reasonably easy to get rid of the hard 2.16 dependency,
and I'll do that for the next release.

However, libmongo-client will depend on either glib >= 2.16 OR OpenSSL,
unless you have strong objections, in which case I'll make the depending
parts of it optional (but I'd like to not do that, if possible).
