build: Migrate to meson build

Meson is a far more robust build framework, compared to autotools. This
greatly simplifies adding new features, since it's far easier to
maintain a set of meson.build files vs the autotools mishmash.

DEPRECATION NOTICE: Autotools based build is deprecated and will be
removed in the future.
