hgweb: remove proxy to hgweb instance We were temporarily routing attributes until all request-specific attributes from hgweb were moved to requestcontext. We have finally reached that juncture and we can remove the proxy. At this point, only the repo instance is prone to race conditions between threads. This will be dealt with shortly.

dispatch: disable demandimport when invoking the debugger Turns out that demandimport confuses pudb, which does some pretty complicated imports. I think it's reasonable to disable demandimport here.

templater: create string unescape helper (issue4798) This gives us a unified place to do error-handling of string-escaping syntax errors

parsers: use PyTuple_New and SET_ITEM to construct metadata pair of markers With these 2 patches, fm1readmarkers() gets slightly faster: obsolete._fm1readmarkers() for 78644 entries 58.0 -> 56.2msec

parsers: use PyTuple_SET_ITEM() to fill new marker tuples Because we know these tuples have no member yet, PyTuple_SetItem() isn't necessary.

revset: uncache filteredset.__contains__ Since 96b6b3d78697, condition function returns a cached value, so there's little benefit to cache __contains__. No measurable difference found in contrib/base-revsets.txt.

hgweb: assign ctype to requestcontext The very existence of ctype is a bit hacky. But we roll with it. Before this patch, there was possibly a race condition between 2 threads handling file requests: 1 thread could set the ctype and another serving a different file would read and use that potentially wrong ctype.
