Once SSLMutex allowed for the setting of both the
locking method and the lockfile location, I never
liked how AcceptMutex was linked to LockFile. This
seemed unnecessary. Much better to have AcceptMutex
do both as well. Plus, now that we will likely see
other modules require a "standard" way of setting
mutexes, why not have Apache provide that as
an API of sorts.

Anyway, LockFile is now depreciated and AcceptMutex
is now SSLMutex-like. We also provide a short
function that "parses" out a mutex parameter
and strips out the mechanism and lockfile location.
AcceptMutex and SSLMutex is this capability.
