This method does the work to check whether or not the components of a path
already exist in different case. We do it by breaking the depot path up
into components where the first part is the depot name, the last part is
the filename and everything in between is a directory name. We then start
at the depot and then iteratively check the directories one by one.

Enforce case checking. the basic algorithm is that we split the depot path
of each file up into its components and use "p4 depots", "p4
dirs" (depending on what level we’re at to locate existing
depots/dirs with the same names in different case. If we find any we reject
submission. Note that we are only interested in new files being
added/branched since existing files are assumed to be OK.
