Corinna Vinschen 877f0d13f0 Cygwin: rmdir: handle /dev in fhandler_dev::rmdir
The isdev_dev check in rmdir is unclean.  Create a virtual method
fhandler_dev::rmdir to handle this transparently.

Ken Brown c561a625af Cygwin: mkdir and rmdir: treat drive names specially
If the directory name has the form 'x:' followed by one or more
slashes or backslashes, and if there's at least one backslash, assume
that the user is referring to 'x:\', the root directory of drive x,
and don't strip the backslash.

Previously all trailing slashes and backslashes were stripped, and the
name was treated as a relative file name containing a literal colon.

Ken Brown d1b5feef82 Cygwin: rmdir: fail if last component is a symlink, as on Linux
If the last component of the directory name is a symlink followed by a
slash, rmdir now fails, following Linux but not POSIX, even if the
symlink resolves to an existing empty directory.

mkdir was similarly changed in 2009 in commit
52dba6a5c4.  Modify a comment to clarify
the purpose of that commit.

Ben Wijen b0c033bf3f mkdir: always check-for-existence
When using NtCreateFile when creating a directory that already exists,
it will correctly return 'STATUS_OBJECT_NAME_COLLISION'.

However using this function to create a directory (and all its parents)
a normal use would be to start with mkdir(‘/cygdrive/c’) which translates
to ‘C:\’ for which it'll instead return ‘STATUS_ACCESS_DENIED’.
