Adrian Ratiu 03b4043b91 hook: include hooks from the config ...

Teach the hook.[hc] library to parse configs to populate the list of
hooks to run for a given event.

Multiple commands can be specified for a given hook by providing
"hook.<friendly-name>.command = <path-to-hook>" and
"hook.<friendly-name>.event = <hook-event>" lines.

Hooks will be started in config order of the "hook.<name>.event"
lines and will be run sequentially (.jobs == 1) like before.
Running the hooks in parallel will be enabled in a future patch.

The "traditional" hook from the hookdir is run last, if present.

A strmap cache is added to struct repository to avoid re-reading
the configs on each rook run. This is useful for hooks like the
ref-transaction which gets executed multiple times per process.

Examples:

  $ git config --get-regexp "^hook\."
  hook.bar.command=~/bar.sh
  hook.bar.event=pre-commit

  # Will run ~/bar.sh, then .git/hooks/pre-commit
  $ git hook run pre-commit
