Graphics-related memory leak fixed in master for post-haswell machines

A memory leak has been fixed in master's drm (gpu) code which affects
post-haswell intel GPUs. i.e. Broadwell, Skylake, etc. This leak would
cause a OOM panic typically after a couple of weeks of uptime. The leak
does not affect older Haswell based intel systems. A number of other
stability improvements have also gone into the system.
The release branch got some of the stability work but the fix for the
graphics memory leak is a bit too complex to backport in a compatible
manner. At the current juncture, anyone running a workstation with release
might want to switch to master. Master will be *much* better on broadwell
or later GPUs.
Also somewhat related, chromium (chrome) has been updated from v52 to v54
on both branches, which fixes some serious GUI issues on high-dpi (aka 4K)
monitors. Chrome 54 still has some issues with certain sites, but
generally speaking it seems to be pretty stable and I recommend its use.
