As part of the refactor, have the sources include the public headers via
the libx52 prefix, instead of relying on the include directories
approach in meson.build
The autotools build infrastructure was deprecated back in 0.3.3, and any
bugs in the Meson build infrastructure have been fixed now. This
eliminates the legacy build scripts which were hard to maintain.
When enabling --warnlevel=3 during Meson setup, the build threw up
several warnings, mostly related to either unused parameters, or
sometimes an integer type mismatch. This commit addresses all of those
changes and ensures that the build does not contain any unnecessary
warnings.
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.
