When configured at compile time via the cmake
VPP_BUFFER_FAULT_INJECTOR option, the buffer allocator will appear to
fail a certain fraction of the time.
By default, the allocator succeeds 80% of the time. Detailed command
line configuration options are available, but only when the image has
been compiled with cmake option described above:
vlib { buffer-alloc-success-rate [0.0 ... 1.0]
buffer-alloc-success-seed <nnnn> }
Modify vlib_buffer_pool_create(...) so 0 is always an invalid buffer
index.
Debug images: add checks for bad buffer index enqueues, and also
verify that f->n_vectors doesn't accidentally map one or more
instances of the frame poison pattern 0xfefefefe.

Introduce AddressSanitizer support: https://github.com/google/sanitizers/
This starts with heap instrumentation. vlib_buffer, bihash and stack
instrumentation should follow.

Set vm->check_frame_queues after actually enqueuing a frame. Under
obscure circumstances, the code managed to set check_frame_queues so
far in advance that 100 dispatch cycles could elapse before the frame
enqueue succeeded. That resulted in permanent lack of queue service.
Type: fix
