bookmark: add an --active flag to display the active bookmark

There is currently no official simple way to retrieve the current bookmark. In
particular for automation.

We add a `--active` flag to the `hg bookmarks` command. When set, the command
display the current bookmark name if any or return 1.

For now, this flag is read-only. However sensible combinations exist with
`--delete`, `--rename` and `--rev` and can be implemented later.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
