Stop spending cycles repeatedly tail-trimming the pool free element
bitmap; possibly at the expense of slightly hurting pool_foreach
peformance.

gcc8 introduced a new warning (Wstringop-truncation) which in our case
is being treated as error.
Disabling the warning globally might introduce bugs related to string
truncation which are not desired by the developer (e.g. bug).
Instead, this patch disables the warning only for those occurences
which have been verified to be non-bugs but the desired behaviour as per
developer will.

A small store into a middle of a larger structure that was subsequently
loaded for calculating the bihash key was noticeably impacting the performance.

Slightly refactored from the initial implementation of the TupleMerge [1]
algorithm by Valerio Bruschi (valerio.bruschi@telecom-paristech.fr)
[1] James Daly, Eric Torng "TupleMerge: Building Online Packet Classifiers
by Omitting Bits", In Proc. IEEE ICCCN 2017, pp. 1-10
Also add startup parameters to turn on/off the algorithm ("use tuple merge 1/0"),
and a startup parameter to be able to tweak the split threshold
("tuple merge split threshold N"), the default value of the split threshold
is 39 as per paper, but some more tuning might be necessary to find the best
value.
This change, alongside with the optimizations which avoid extra lookups,
significantly reduces the slowdown on the ClassBench generated ACLs, which
are supposed to resemble realistic ACLs seen in use in the field.

- avoid reading/setting total_length_not_including_first_buffer. It's
part of a buffer's second cache line so it comes at a "cost".

crash stack backtrace will be directed to syslog
1. make use of glic backtrace in execinfo.h. the old clib_backtrace is removed
2. install SIGABRT in signal handler, but have to remove it when backtrace is
done. reason is to capture stack trace caused by SIGABRT. vPP ASSERT always
call os_exit then abort(). we definitely want to know the trace of this
situation. It is a little tricky to avoid SIGABRT infinite loop
3. always load symbols by calling clib_elf_main_init () in main(). Otherwise,
PC addresses instead of symbols will be displayed.

- instantiate the per-use mask type entry for a given hash ACE
this prepares to adding tuplemerge where the applied ACE may
have a different mask type due to relaxing of the tuples
- store the vector of the colliding rules for linear lookups
rather than traversing the linked list.
- store the lowest rule index for a given mask type inside
the structure. This allows to skip looking up at the later
mask types if we already matched an entry that is in front
of the very first entry in the new candidate mask type,
thus saving a worthless hash table lookup.
- use a vector of mask type indices rather than bitmap,
in the sorted order (by construction) of ascending
lowest rule index - this allows to terminate the lookups
early.
- adapt the debug cli outputs accordingly to show the data
- propagate the is_ip6 into the inner calls

I suppose most API handlers do not use vm parameter so it has not
been a problem so far. Now vl_api_vnet_set_ip6_ethernet_neighbor()
was crashing when called from api trace replay because either of
ip_neighbor_add_del_t_handler() vnet_arp_set_ip4_over_ethernet()
need vm to be correct when it calls vlin_time_now() to update the
neighbor timestamp.

This change adds handling of special case when setUpClass throws. In
this case TestResults receives a mock object called _ErrorHolder.
By parsing its description, we find test class name and use it to lookup
the test class in test suite to be able to add it to the list of failures
for re-running.

It would seem that this avoids using the stack for computing the
subsequent crc32 by storing the 2 x u64 ip4 5-tuple key into two
registers. Probably the cast to the "convenience" data structure "masks"
the fact that the key is 16B. Probably ... :-)
"sh run" on an ip4 tcp sender reports that the number of clocks spent in
tcp_input, where a session lookup is performed, drops ~25% (from ~100
clocks/packet to ~75 clocks/packet)
