templater: split template functions to new module It has grown enough to be a dedicated module.

templater: move hybrid class and functions to templateutil module And make _hybrid and _mappable classes public. _showlist() is still marked as private since it's weird and third-party codes shouldn't depend on it.

templater: move stringify() to templateutil module As we have a util module, it doesn't make sense to import stringify() from templatefilters.py.

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.
