- Add ability to temporarily disable expensive stat() functionality.

Useful to speed up directory traversals which don't need correct 
permission bits, for example:

$ CYGWIN=stat:noacl,notexec find /large/dirtree -type f -mtime +365

Alternatively allow to override mount options also for other functions 
like chmod(), for example:

$ CYGWIN=mount:noacl chmod -w file # sets R/O attribute
$ CYGWIN=mount:noacl touch new_file # inherits ACL

(The latter is possibly easier to implement by changing MOUNT_* in path.*)


- Add ability to specify mount options for individual /cygdrive/s.

For example useful to add 'notexec' for slow USB flash drives:

none /cygdrive cygdrive binary,posix=0,user,noacl 0 0
none /cygdrive/f cygdrive binary,posix=0,user,noacl,notexec 0 0

(No idea how to implement this, sorry)
