Backport Meson build support

Meson builds have better integration with Vala. For example, Meson
handles incremental compilation of Vala source files better than
CMake.

Limitations:

As done with CMake builds, gresource.xml should be compiled. Now, it has
been generated from a CMake build and manually copied into the source
tree.
