When releasing HTTP waiters, avoid unnecessary sort activity.
For Content-Type in responses, let libcurl do the work and removed
my parsing of headers. Drop Content-Encoding as libcurl will deal
with that. If anyone is interested, they can parse.
HttpResponse object now has two strings for these content headers.
Either or both may be empty. Tidied up the cross-platform string
code and got more defensive about the length of a header line.
Integration test for the new response object.
First, try to issue ranged GETs that are always at least partially
satisfiable. This will keep Varnish-type caches from simply sending
back 200/full asset responses to unsatisfiable requests. Implement
awareness of Content-Range headers as well. Currently they're not
coming back but they will be someday.
This is the first functional viewer pass with the HTTP work of the texture fetch
code performed by the llcorehttp library. Not exactly a 'drop-in' replacement
but a work-alike with some changes (e.g. handler notification in consumer
thread versus responder notification in worker thread).
This also includes some temporary changes in the priority scheme to prevent
the kind of priority inversion found in VWR-28996. Scheme used here does
provide liveness if not optimal responsiveness or order-of-operation.
The llcorehttp library at this point is far from optimally performing.
Its worker thread is making relatively poor use of cycles it gets and
it doesn't idle or sleep intelligently yet. This early integration step
helps shake out the interfaces, implementation niceties will be covered
soon.
