Subject: [PATCH] orc: 0.4.29 -> 0.4.32

* transition from name to pname + version
* change the build system to meson, as autotools is no longer supported by upstream
* optionally build devdoc output
* whatever the reason for manipulating the pkgconfig,
  omitting it doesn't seem to break the build of orc
  or any of its direct reverse dependencies
