Request ownership is no longer flaky. Requests are now owned by the code that makes requests, and Requests and the RequestManager co-own RequestHandles. RequestManager disowns a RequestHandle if it's done with it or if Request code reports that it's no longer needed.
All libcurl code has been moved to RequestManager. This is nice because once NOHTTP is removed, we can add any number of RequestManager implementations, for example one for Android.
Client outliving RequestManager is still a problem, this will have to be addressed later.
Also restore concurrent connection / stream counts, and fix a bug that would cause AvatarButtons to try to fetch avatars before they knew what name they belonged to. I apparently broke this in the first PNG commit.
Also write PNGs with libpng, and BMPs with SDL, and have the renderer only generate a large PNG thumbnail, and disable HTTP/2 multiplexing for now so we don't get banned when loading avatars.
simon pls reply to the stupid emails already.
There are *no* more spacing issues. I used tabs exclusively.
Also, I made changes off of the develop branch.
Here's the Ruby regex that I used:
text.gsub!(/(( |\t)*)if ?\((.*)\) ?{?\n?( |\t)*(free ?\(|delete |delete\[\] )(.*)\)?;/, "\\1\\5\\6;")
