Following the new meson porting guidelines, this patch renames the
build options. The list of changes is as follows:
- Remove the enable prefix from boolean options.
- The character separator from multi-word options has been changed
to underscore.
The warning compiler options are also removed because meson's
compiler related options should be used.
