Added support for the SCMP_ACT_LOG action and SCMP_FLTATR_CTL_LOG attribute

Added explicit 32-bit (SCMP_AX_32(...)) and 64-bit (SCMP_AX_64(...)) argument comparison macros to help protect against unexpected sign extension

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

Numerous documentation fixes and updates
