scmutil: handle full hex nodeids in revsymbol() This is a bit unfortunate, but it enables moving other pieces out of changectx's constructor without affecting the order in which we look up things (e.g. hex nodeid before bookmark). We convert nodeid to revnum before calling repo.__getitem__, even though that will result in converting back to nodeid later. This is so we can handle the LookupError and attempt to interpret the string as something else (e.g. a bookmark). We also need to start handling WdirUnsupported now, since the full hex nodeid "ffff..." represents the working directory. The exception is raised by the revlog layer.

context: handle stringified ints in revsymbol() This patch copies the handling of stringified ints from changectx's constructor. It then calls repo.__getitem__ with the int. Since that method only interprets integers as revnums the first thing it does, this will not be redoing any of the work already done. We leave the old code in place so we can later deprecate it instead of breaking extensions. Differential Revision: https://phab.mercurial-scm.org/D3146

py3: workaround comparing NoneType and integers Comparing None with integers was fine in Python 2 but returns error in Python 3 which is nice. This patch replaces None with -1 where sorting is done and some related logic. Differential Revision: https://phab.mercurial-scm.org/D3219
