DRTVWR-209 Merge of viewer-development with SH-3316 drano-http code.

This was yet another refresh from v-d because of significant changes
to lltexturefetch that would not have been resolvable by casual
application of any merge tool.  There are still a few questions
outstanding but this is the initial, optimistic merge.
