tests: convert the 'file://\$TESTTMP' rule to an automatic substitution
The rule only triggered on non Windows platforms, even though Windows also
required an adjustment. Automatic seems better.
The aggressive globbing in test-subrepo-svn.t was found and rewritten by the
substitution.
This tests the interaction between the largefiles and lfs extensions, and
conversion from largefiles -> lfs.

Setup a repo with a normal file and a largefile, above and below the lfs
threshold to test lfconvert. *.txt start life as a normal file; *.bin start as
an lfs/largefile.

Add an lfs file and normal file that collide with files on the other branch.
large.bin is added as a normal file, and is named as such only to clash with the
largefile on the other branch.

Merge largefiles into lfs branch
The largefiles extension will prompt to use the normal or largefile when merged
into the lfs files. `hg manifest` will show standins if present. They aren't,
because largefiles merge doesn't merge content. If it did, selecting (n)ormal
would convert to lfs on commit, if appropriate.
BUG: Largefiles isn't running the merge tool, like when two lfs files are
merged. This is probably by design, but it should probably at least prompt if
content should be taken from (l)ocal or (o)ther as well.

The merged lfs.bin resolved to lfs because the (n)ormal option was picked. The

When both largefiles and lfs are configured to add by size, the tie goes to
largefiles since it hooks cmdutil.add() and lfs hooks the filelog write in the
commit. By the time the commit occurs, the tracked file is smaller than the
threshold (assuming it is > 41, so the standins don't become lfs objects).
$ $PYTHON -c 'import sys ; sys.stdout.write("y\n" * 1048576)' > large_by_size.bin
$ hg --config largefiles.minsize=1 ci -Am 'large by size'

$ hg rm large_by_size.bin
$ hg ci -m 'remove large_by_size.bin'
Largefiles doesn't do anything special with diff, so it falls back to diffing
the standins. Extdiff also is standin based comparison. Diff and extdiff both
work on the original file for lfs objects.

A largefiles repo can be converted to lfs. The lfconvert command uses the
convert extension under the hood with --to-normal. So the --config based
parameters are available, but not --authormap, --branchmap, etc.
