Opening the repository hooks environment file

We have already picked up one new file on every access in 1.8: the hooks
environment file. This appears to be opened and parsed for every time
mod_dav_svn opens the repository, both read and write operations.

Perhaps we should require an explict config setting to enable the hooks
file so that we can avoid opening it when it is empty? Or perhaps we
could make the opening/parsing lazy and delay it until running a hook
thus avoiding it for read operations?
