log: add bookmark option to "hg log"
Before pushing a bookmark with "hg push origin -B 'my-topic'", it is useful to inspect
the list of commits that are ancestors of the bookmark.
By relying on scmutil.bookmarkrevs(), "hg log -B topic" has the same bookmark semantics
found in other commands like hg export, hg email, hg strip.

Test 'hg log' with a bookmark
Create the repository
$ hg init Test-D8973
$ cd Test-D8973
$ echo "bar" > foo.txt
$ hg add foo.txt
$ hg commit -m "Add foo in 'default'"
Add a bookmark for topic X
$ hg branch -f sebhtml
marked working directory as branch sebhtml
(branches are permanent and global, did you want a bookmark?)
$ hg bookmark sebhtml/99991-topic-X
$ hg up sebhtml/99991-topic-X
0 files updated, 0 files merged, 0 files removed, 0 files unresolved
$ echo "X" > x.txt
$ hg add x.txt
$ hg commit -m "Add x.txt in 'sebhtml/99991-topic-X'"
$ hg log -B sebhtml/99991-topic-X
