- fixes CVE-2017-5461 and CVE-2017-5462
- drop ubsan-alignment.patch.0, there is apparently now some
  NO_SANITIZE_ALIGNMENT macro upstream to get this effect
- drop some hunks to prevent hard-coding CC/CCC vars, upstream now
  respects environment vars (but doesn't quote them...)
- drop first hunk of ubsan.patch.0, fixed upstream
- drop hunk for gtest-internal.h, header looks much newer anyway
