just barely working udate downloading service; missing little nicities like error checking and sill stuff like that.

This reduces the number of symbols in the viewer binary by about 30%.
Also, fixed test errors revealed by inlining being enabled.

Added some logging to viewer_manifest.py to attempt to narrow down the Mac packaging failures a bit.

This is ignored by every compiler except Linux g++ 4.4.3 in Release mode. In
that case, it literally does cause getInstance() to be inlined, therefore
llmoveview.o contains no such symbol, therefore the Linux viewer link fails in
Release mode. But for a method implementation in a .cpp file of a method
declared in a .h file, 'inline' is just wrong. Removing it fixes Release build.

VWR-23666 Removed setting VersionChannelName. LLVersionInfo::resetChannel() and unit tests. Reviewed by brad.

2.6.4 fixes a Mac bug in get_target_property(... "SLPlugin" LOCATION): before
that version it returns "pathname/SLPlugin", whereas the correct answer is
"pathname/SLPlugin.app/Contents/MacOS/SLPlugin". With 2.6.2, the Mac build
breaks in a mysterious way. Changing this version requirement should clarify
the solution.

LLTextBase::setCursor() sometimes failed to work properly if line wrapping was enabled.
This is a slightly optimized version of the patch made by Satomi Ahn.
