Make us pass RAW-CHKPATH with a case sensitive share.
I know Volker will look at this closely so here's the explaination :-). Originally on a case-sensitive share we simply did a stat (or lstat) call and returned success of fail based on the result. However this failed to take account of incoming paths with a wildcard (which must always fail, and with different error messages depending on whether the wildcard is the last component or in the path). Also it failed to take account of a stat fail with ENOENT due to a missing component of the path as the last component (which is ok as it could be a new file) or if the ENOENT was due to the missing component within the path (not the last component) - which must return the correct error. What this means is that with "case sensitive = yes" we do one more talloc call (to get the parent directory) and one more stat call (on the parent directory) in the case where the stat call fails. I think this is an acceptable overhead to enable case sensitive shares to return the correct error messages for applications. Volker please examine carefully :-). Jeremy.
