1) Add in smb_file_time struct to clarify code and make room for createtime. 2) Get and set create time from SMB messages. 3) Fixup existing VFS modules + examples Some OS'es allow for the setting of the birthtime through kernel interfaces. This value is generically used for Windows createtime, but is not settable in the code today.

* Catia VFS module

|
* Implement a fixed mapping of forbidden NT characters in filenames that are

|
* used a lot by the CAD package Catia.
|
|
*
|
|
* Yes, this a BAD BAD UGLY INCOMPLETE hack, but it helps quite some people
|
|
* out there. Catia V4 on AIX uses characters like "<*$ a *lot*, all forbidden
|
|
* under Windows...
