Added an option to create a mountpoint with a missing directory (#354)
* Added an option to create a mountpoint with a missing directory

It skips the normal confirmation message, which makes cryfs easier
to use in scripts, or can be aliased for quicker use.

* separated basedir and mountpoint autocreate flags, and added tests

* Werror and clang-tidy fixes
added to the ChangeLog

* fixed the bugs that clang-tidy caused

never used clang before, so I don't really know what it did and why it
caused compile errors
