dagop: move lines() out of annotate()

dagop: extract core algorithm of annotate() from context.py See the previous patch for why.

dagop: move annotateline and _annotatepair from context.py The annotate logic is large. Let's move it out of the context module, which is basically an abstraction layer of repository operations.

bdiff: convert more longs to int64_t MSVC previously flagged these where the function is stored in a pointer: bdiff.c(284) : warning C4028: formal parameter 1 different from declaration bdiff.c(284) : warning C4028: formal parameter 2 different from declaration bdiff.c(284) : warning C4028: formal parameter 3 different from declaration bdiff.c(284) : warning C4028: formal parameter 4 different from declaration

xdiff: silence a 32-bit shift warning on Windows It's probably harmless, but: warning C4334: '<<' : result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?) Adding a 'ULL' suffix to 1 also works, but I doubt that's portable.

xdiff: backport int64_t and uint64_t types to Windows Sadly, MSVC 2008 lacks stdint.h. These are the only two definitions needed right now.

templater: extract template evaluation utility to new module Prepares for splitting template functions to new module. All eval* functions were moved to templateutil.py, and run* functions had to be moved as well due to the dependency from eval*s. eval*s were aliased as they are commonly used in codebase. _getdictitem() had to be made public.

templater: move function table to the "context" object Prepares for splitting template functions from templater.py.

hgweb: remove wsgirequest (API) Good riddance. .. api:: The old ``wsgirequest`` class for handling everything WSGI in hgweb has been replaced by separate request and response types. Various high-level functions in the hgweb WSGI applications now receive these new types as arguments instead of the old ``wsgirequest`` type.

tweakdefaults: add commands.status.verbose to tweakefaults commands.status,verbose if set to True, shows conflict information in `hg status`. It shows which unresolved state you are in, which are the unresolved files and how to continue the unresolved state. That sounds like a very good candidate for tweakdefaults. bisect is added to commands.status.skipstates because people generally leave unresolved bisect state and we should skip that in morestatus output.

hgweb: store the raw WSGI environment dict We need this so we can construct a new request instance from the original dict. Differential Revision: https://phab.mercurial-scm.org/D2831

hgweb: remove dead wsgirequest code All responses now go through our modern response type. All code related to response handling can be deleted. Differential Revision: https://phab.mercurial-scm.org/D2830

hgweb: port to new response API These were the last consumers of wsgirequest.respond() \o/ Differential Revision: https://phab.mercurial-scm.org/D2829

hgweb: pass modern request type into templater() Only a handful of consumers of wsgirequest remaining in this file... Differential Revision: https://phab.mercurial-scm.org/D2828

hgweb: use modern response type for index generation Differential Revision: https://phab.mercurial-scm.org/D2827
