subrepo: rename the '_ui' member to 'ui'
The localrepository class has a 'ui' member, so keeping the names the same will
allow for duck typing with subrepo instances when accessing 'ui'. Changing this
is easier than finding all of the localrepository instance uses and renaming
that to '_ui'.

Issue1790: dirstate entry locked into unset if file mtime is set into
the future
Prepare test repo:
$ hg init u
$ cd u
$ echo a > a
$ hg add
adding a
$ hg ci -m1
Set mtime of a into the future:
$ touch -t 202101011200 a
Status must not set a's entry to unset (issue1790):
$ hg status
$ hg debugstate
n 644 2 2021-01-01 12:00:00 a
Test modulo storage/comparison of absurd dates:
#if no-aix
$ touch -t 195001011200 a
$ hg st
$ hg debugstate
n 644 2 2018-01-19 15:14:08 a
