Makes sure we use the LoopbackRouteFetcher, and also wires up AddHeadersFetcher.
Note that this pulls in loopback_route_fetcher.cc from svn revision r2649
The LoopbackRouteFetcher is applied unconditionally, while in mod_pagespeed it
is not applied when one of these configuration settings is true:
* disable_loopback_routing
* slurping_enabled, or
* test_proxy is set
I added a TODO for that.
(Sqash-merge of Otto's #193.)
We want people to be able to install ngx_pagespeed like any other nginx module.
If PSOL were a full-fledged library with a stable interface we could simply say
"install PSOL" which might be as easy as `apt-get install psol-dev`, but it's
not. Instead we directly include a precompiled binary library along with its
headers. By building the binaries on something sufficiently old (Centos 5.4)
they should work pretty much everywhere someone might think to run
ngx_pagespeed, but building from source is still a documented option if they
don't.
Headers and binaries are from trunk of r2338, as documented in the READMEs.
