libselinux: Enable many more gcc warnings for libselinux/src/ builds

XXX:  -Wno-redundant-decls really shouldn't be set, if some way
can be found to deal with warnings generated by dso.h

XXX: the maximum stack size should be much lower, but there
are too many functions using PATH_MAX which need to be rewritten
to use the heap instead.

XXX: probe for whether the user's GCC supports a flag ?
