Add Meson build system

This should be on par with the autoconf build. Like autoconf it
defauilts to generating both a shared and static library. I have
intentionally not used the pkg-config template, and used Meson's
pkg-config generator instad. This provides dependency and include
tracking that would otherwise have to be done manually.
