bookmarks: consider successor changesets when moving bookmark (
issue4015)
Previously, this required -f because we didn't consider obsolete changesets
(and their children ... or successors of those children, etc.). We now use
obsolete.foreground to calculate acceptable changesets when advancing the
bookmark.
Test coverage has been added.

Make sure update doesn't assume b1 is a repository if invoked from outside:
$ cd ..
$ hg update b1
abort: no repository found in '$TESTTMP' (.hg not found)!

$ cd b1
Test helper functions:
$ revtest () {
> msg=$1
> dirtyflag=$2 # 'clean', 'dirty' or 'dirtysub'
> startrev=$3
> targetrev=$4
> opt=$5
> hg up -qC $startrev

$ norevtest () {

> test $dirtyflag = dirty && echo dirty > foo
> test $dirtyflag = dirtysub && echo dirty > sub/suba
> hg up $opt

Test cases are documented in a table in the update function of merge.py.
Cases are run as shown in that table, row by row.
