Avoid a potential integer underflow in the lock timeout value sent back to a client. The answer to a LOCK request could be an extremly large integer if the time needed to lock the resource was longer that the requested timeout given in the LOCK request. In such a case, we now answer "Second-0".  PR55420

Remove some instances where a RewriteBase must be specified

Previously, any time you used a relative substitution in 
per-directory/htaccess context, you needed to specify
a RewriteBase. But in case where the context document root 
and context prefix are known via e.g. mod_userdir
or mod_alias, and the substitution is under the context 
document root, we can determine the replacement automatically.

This makes htaccess files or config snippets a bit more
portable.
