Add test cases for static and dynamic minor number allocation and
deallocation.
While at it, improve description and test suite name.
Some of the cases include:
- that static and dynamic allocation reserved the expected minors.
- that registering duplicate minors or duplicate names will fail.
- that failing to create a sysfs file (due to duplicate names) will
deallocate the dynamic minor correctly.
- that dynamic allocation does not allocate a minor number in the static
range.
- that there are no collisions when mixing dynamic and static allocations.
- that opening devices with various minor device numbers work.
- that registering a static number in the dynamic range won't conflict with
a dynamic allocation.
This last test verifies the bug fixed by commit

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
