hg-cpython: use ancestor iterator impls from vcsgraph
Differential Revision: https://phab.mercurial-scm.org/D11947
Windows needs ';' as a file separator in an environment variable, and MSYS
doesn't automatically convert it in every case.

Test config default of various types:
{"defaultvalue": ""} for -T'json(defaultvalue)' looks weird, but that's
how the templater works. Unknown keywords are evaluated to "".

The feature is experimental and behavior may varies. This test exists to make sure the code is run. We grep it to avoid too much variability in its current experimental state.

Simple order checking
---------------------
If file B is read after file A, value from B overwrite value from A.
$ HGRCPATH=`path_list_var "file-A.rc:file-B.rc"` hg config config-test.basic
value-B
Ordering from include
---------------------
value from an include overwrite value defined before the include, but not the one defined after the include
$ HGRCPATH="file-A.rc" hg config config-test.pre-include
value-included
$ HGRCPATH="file-A.rc" hg config config-test.post-include
value-A
command line override
---------------------
$ HGRCPATH=`path_list_var "file-A.rc:file-B.rc"` hg config config-test.basic --config config-test.basic=value-CLI
value-CLI
Alias ordering
--------------
The official config is now `command-templates.log`, the historical
`ui.logtemplate` is a valid alternative for it.
When both are defined, The config value read the last "win", this should keep
being true if the config have other alias. In other word, the config value read
earlier will be considered "lower level" and the config read later would be
considered "higher level". And higher level values wins.
$ HGRCPATH="file-A.rc" hg log -r .
value-A
$ HGRCPATH="file-B.rc" hg log -r .
value-B
$ HGRCPATH=`path_list_var "file-A.rc:file-B.rc"` hg log -r .
value-B
Alias and include
-----------------
The pre/post include priority should also apply when tie-breaking alternatives.
See the case above for details about the two config options used.
$ HGRCPATH="file-C.rc" hg log -r .
value-C
$ HGRCPATH="file-D.rc" hg log -r .
value-included
command line override
---------------------
$ HGRCPATH=`path_list_var "file-A.rc:file-B.rc"` hg log -r . --config ui.logtemplate="value-CLI\n"
value-CLI
