convert: support incremental conversion with hg subrepos
This was implied in issue3486, which specifically asked for subrepo support in
lfconvert. Now that lfconvert uses the convert extension internally when going
to normal files, the issue is half fixed. But now even non largefile repos
benefit when other transformations are needed.
Supporting a full subrepo tree conversion from a single command doesn't seem
reasonable, given the number of options that can be provided, and the
transformations that would need to occur when entering a subrepo (consider
'filemap' paths). Instead, this allows the user to incrementally convert each
hg subrepo from bottom up like so:
# so convert knows the dest type when it sees a non empty dest dir
$ hg init converted
$ hg convert orig/sub1 converted/sub1
$ hg convert orig/sub2 converted/sub2
$ hg convert orig converted
This allows different options to be applied to different subrepos more readily.
It assumes the shamap is in the default location in each converted subrepo for
simplicity. It also allows for a subrepo to be cloned into place, in case _it_
doesn't need a conversion. I was able to convert away from using
largefiles/bfiles in several subrepos with this mechanism.
