This helper returns the VT-number for the given VT if, and only if, it
is a real VT. In all other cases 0 is returned.

This adds the uvt_client symbols to the public symbol list and exports
them so we can use them in uvtd.

Two new functions to retrieve the current major number and dynamically
allocate minor numbers.
This can be used by clients that allocate more than one CDEV for VTs to
dynamically retrieve a new minor number.

We need to export the symbols to make use of them. This exports all useful
ctx+cdev functions for outside use. The other subsystems still need to get
reviewed before we export them.

UVT is based heavily on the old cdev-sessions. It uses CUSE/FUSE to
implement virtual terminals in user-space.
This move into a library allows to use it in other projects, too. There is
no reason to limit it to kmscon sessions. In fact, we will remove the
cdev-sessions, soon and make kmscon a stand-alone terminal emulator
without any session capability.
Instead, the uvtd program will provide the VT emulation.
This library is not finished, nor ready for use. However, feel free to
contribute patches so we can eventually release a stable API.

Major overhaul of the build system. This introduces symbol-versioning for
all exported libraries. Please note that none of these libraries is
stable, yet!
