Make this package more awesome. Remove parts of
patches/patch-uwsgiconfig.py which disabled the pcre, yaml, json, and
libuuid for the users. Replace this with the options + SUBST framework to
enable the user to access these options. Install example files to their
usual location. Buildlink pthread and dlopen. Bump PKGREVISION.
Use options framework instead of disabling certain package options for the
user via a patch. By force-disabling PCRE, we turn off internal routing
support in this package. Let the user decide.
