hg: avoid auto sharing when the clone destination is remote
Before this patch, when auto sharing is enabled, 'hg.clone()' tries to
create local clone regardless of locality of the clone destination on
the host, and causes failure.
To avoid auto sharing when the clone destination is remote, this patch
adds examination of 'islocal(dest)' before auto sharing in
'hg.clone()'.
'islocal(dest)' is examined after 'sharepool', because:
- the former is more expensive than the latter
- without enabling share extension, the later is always negative
largefiles: ensure lfutil.getstandinmatcher() only matches standins
Previously, simply having the largefiles extension loaded without any largefiles
added would crash when amending with -I. The problem was with no files in the
matcher, the pattern list of files joined with 'standindir' was empty, and
scmutil.match() would match everything. In lfutil.composestandinmatcher(), the
match function is used to test if the file is a standin, and after getting a
false positive, proceeds to call lfutil.splitstandin(). This returns None
because it isn't a standin, which blows up when passed to rmatcher.matchfn().
Manually overriding _always in getstandinmatcher() probably isn't necessary
anymore, but we leave well enough alone on stable. This regressed in
