We will shortly be feeding more information into the process of
creating array devices, so delay the creation. Still open them
early if the device already exists.
This involves making sure the autof flag is in the right place
so that it can be found at creation time.
Also, Assemble, Build, and Create now always close 'mdfd'.

This reflect that fact that more often than not it is creating things
in /dev, and allows for a new open_mddev which does just that.

- Fix a bug where mdassemble didn't close a filedescriptor and so couldn't assembele
stacked arrays.
- Allow mdassemble, when run a second time, to mark all arrays as writable.
This is useful if they are started read-only as is best at boot-time.
pass CFLAGS to mdassemble build, enabling -Wall -Werror showed some
issues also fixed by the patch.
