colladadom to 290229, curl to 290186, fontconfig to 290258, freetype to 290255,
google-mock/gmock/gtest to 290199, libpng to 290081, libxml2 to 290157,
llqtwebkit to 290262/250147 (to be fixed shortly), openssl to 290083,
pcre to 290150, zlib to 290080.  The freetype2 headers are now normalized
to what they would normally be on a unix-type system.  Libxml2 and
pcre are available on all platforms.  Libraries generally move in the
direction of static archives rather than shared libraries (e.g. openssl).
The llqtwebkit side is a step back from the more ambitious goal.  What
will be used (290262) will be a simple rebuild of the existing 4.7.1
library with updated package dependencies.  The bigger work will be in
the future.

Hack librt inclusion into llcommon for all Linux builds.  The dep is needed for llcommon, but it was being satisfied elsewhere for viewer builds and got to dodge the problem.  This should quieten the server builds somewhat.

Some branch shenannigans in the pluginapi_05 branch caused this to become a two-part merge.
