dev-libs/libffi: use preserve-libs.eclass 1. Revision bump to re-install libffi now that glibc definitely has the correct version bounds on pax-utils. See linked bug for more information. This is unrelated to the preserve-libs eclass change, but we figured we should do this just as a nudge to help people in a "damaged" situation (see bug). 2. Use preserved-libs.eclass because SONAME of libffi changed from 7 -> 8. FEATURES="preserved-libs" (distinct from the eclass) is not required to be used (even if encouraged) and is not part of PMS, so alternative package managers to Portage don't have to implement it. Use the eclass to perserve libffi.so.7 to keep dev-lang/python working. Runtime failures will occur without Python being rebuilt in time. (Unfortunately, the same is true for the rewritten-in-Python revdep-rebuild, so revdep-rebuild.sh may help folks who are already bitten by this.)
