misc: add address sanitizer heap instrumentation
Introduce AddressSanitizer support: https://github.com/google/sanitizers/ This starts with heap instrumentation. vlib_buffer, bihash and stack instrumentation should follow. Type: feature Change-Id: I7f20e235b2f79db72efd0e756f22c75f717a9884 Signed-off-by: Benoît Ganne <bganne@cisco.com>
