[PATCH] Add a '--fsfs-no-repsharing' flag to svnadmin

The general idea of the patch is to introduce new svnadmin option
and FSFS filesystem configuration option to allow enabling/disabling
repository sharing on FSFS.

I am not sure that SQLite locking works correctly over network share
due the limit file level locking support offered by OS for network shares.
SQLite is used for repository sharing so it may lead to repository corruption.
svnadmin and filesystem configuration options help users control this issue.

The log message is as follows:
