Closes #8912

Added the red dot (instead of the default `*`) if the branch is dirty.

The bira theme only supported git, now it supports mercurial as well. It
needed ito call `hg_prompt_info` and the `ZSH_THEME_HG_PROMPT_`
variables.

Closes #6631

BREAKING CHANGE: the `hg_prompt_info` function now uses `ZSH_THEME_HG_PROMPT_PREFIX`
and `ZSH_THEME_HG_PROMPT_SUFFIX` variables when displaying branch information, similar
to the `git_prompt_info` function.

Closes #6631

Replaced two different calls of hg with one `hg --id --branch` for retrieving
information whether we're in a repo (will be empty if not), whether the repo is
dirty (revision id will contain "+" if there are uncommitted changed), and the
branch name.
