patch 9.0.0411: only created files can be cleaned up with one call

Browse Source 
Problem:    Only created files can be cleaned up with one call.
Solution:   Add flags to mkdir() to delete with a deferred function.
            Expand the writefile() name to a full path to handle changing
            directory.

Create directory {name}.
If {path} is "p" then intermediate directories are created as
necessary. Otherwise it must be "".
If {path} contains "p" then intermediate directories are

If {path} contains "D" then {name} is deleted at the end of

defer delete({name}, 'rf')
< Note that when {name} has more than one part and "p" is used
some directories may already exist. Only the first one that
is created and what it contains is scheduled to be deleted.
E.g. when using: >
call mkdir('subdir/tmp/autoload', 'pR')

scheduled for deletion, like with: >
defer delete('subdir/tmp', 'rf')
< Note that if scheduling the defer fails the directory is not
deleted. This should only happen when out of memory.
If {prot} is given it is used to set the protection bits of
the new directory. The default is 0o755 (rwxr-xr-x: r/w for
