It's easy to have the per-repository svnserve.conf and the passwd
information be merged on top of the global svnserve.conf and passwd
using svn_config_merge().

It's not clear to me if we want to support merging of passwd and authz
date though. Also, we have no public API for merging authz data,
although under the hood, authz is a svn_config_t.

Do we want to leave it to the administrator to ensure they're not doing
something stupid like opening a hole in one repository when they modify
the global authz file?

Also, given this is security related, maybe we want to provide the
option of merging or replacing the global data? The setting could be
named "per-repository-configuration" and have the following settings:

- ignore
   Ignore any per-repository config's
- replace
   Replace any global svnserve.conf, passwd and authz data with the
- merge
   Merge in any svnserve.conf, passwd and authz data

It sounds like the safest is ignore and replace, with a merge being
something maybe the administrator should explicitly use.

I can add a check in the code for --config-file that checks for a
"per-repository-configuration" option, once we work out the design here.
