r8340: - added sys_gmtime()
- added sys_unlink()
- added sys_file_load() and sys_file_save()
- use mprString() instead of mprCreateStringVar() to cope with NULL strings
- removed smbcalls_irpc.c as its not needed any more
- allow ldbAdd() and ldbModify() to take multiple ldif records
- added a sprintf() function to ejs. Quite complex, but very useful!
(This used to be commit 625628a3f6e78349d2240ebcc79081f350672070)
