template: add predecessors template
Add a 'predecessors' template that returns the list of all closest known
predecessors for a changectx. The elements of the list are row changectx node id
formatted by default as short nodes.
The "closest predecessors" are the first locally known revisions encountered
while, walking predecessors markers. For example:
1) If a (A, (B)) markers exists and both A and B are locally known A is a
closest predecessors of B.
2) If a (A, (B)) and (B, (C)) markers exists and only A and C are known
locally, A will be the closest precursors of C.
This logic respect repository filtering. So hidden revision will be skipped by
this logic unless --hidden is specified. Since we only display the visible
predecessors, this template will not display anything in most case. It makes a
good candidate for inclusion in the default log output.
I added a new test-file for testing the precursors in various scenarios. This
test file will also be used for the successors template.
A new "obsutil" module has been added to start gathering utility function
outside of the large obsolete.py module.

Preparing the subrepository 'sub'
$ hg init sub
$ echo sub > sub/sub
$ hg add -R sub
adding sub/sub (glob)
$ hg commit -R sub -m "sub import"
Preparing the 'main' repo which depends on the subrepo 'sub'
$ hg init main
$ echo main > main/main
$ echo "sub = ../sub" > main/.hgsub
$ hg clone sub main/sub
updating to branch default
1 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ hg add -R main
adding main/.hgsub (glob)
adding main/main (glob)
$ hg commit -R main -m "main import"
Cleaning both repositories, just as a clone -U
$ hg up -C -R sub null
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg up -C -R main null
0 files updated, 0 files merged, 3 files removed, 0 files unresolved
$ rm -rf main/sub
hide outer repo
$ hg init
Serving them both using hgweb
$ printf '[paths]\n/main = main\nsub = sub\n' > webdir.conf
$ hg serve --webdir-conf webdir.conf -a localhost -p $HGPORT \
> -A /dev/null -E /dev/null --pid-file hg.pid -d
$ cat hg.pid >> $DAEMON_PIDS
Clone main from hgweb
$ hg clone "http://localhost:$HGPORT/main" cloned
