Added support for the parisc and parisc64 architectures - Added the ability to query and set the libseccomp API level via seccomp_api_get(3) and seccomp_api_set(3) - Return -EDOM on an endian mismatch when adding an architecture to a filter - Renumber the pseudo syscall number for subpage_prot() so it no longer conflicts with spu_run() - Fix PFC generation when a syscall is prioritized, but no rule exists - Numerous fixes to the seccomp-bpf filter generation code - Switch our internal hashing function to jhash/Lookup3 to MurmurHash3 - Numerous tests added to the included test suite, coverage now at ~92% - Update our Travis CI configuration to use Ubuntu 16.04 -
