rdma: fix bug related to ring buffer

Fix a bug that caused some input packets to be dropped due to errors of
the type 'ip4 length > l2 length'. The change is related to the second
call to the rdma_device_input_bufs() function that happens when the end
of the ring buffer is reached.

misc: fix coverity warnings

Add an ALWAYS_ASSERT (...) macro, to (a) shut up coverity, and (b)
check the indicated condition in production images.

As in:
 p = hash_get(...);
 ALWAYS_ASSERT(p) /* was ASSERT(p) */
 elt = pool_elt_at_index(pool, p[0]);

This may not be the best way to handle a specific case, but failure to
check return values at all followed by e.g. a pointer dereference
isn't ok.

Type: improvement

IKE will bring the tunnel up ince the negociation is complete and bring
it down when the session ends. It is the clinets responsibility to

associated with the IKE session.

misc: fix the MAKE_PARALLEL_JOBS for 'make verify' target

MAKE_PARALLEL_JOBS was prepending "-j", which in case of nested targets like "verify"
resulted in ninja being executed with "-j -j" flags.

Solution: prepend -j only at the moment of setting the MAKE_PARALLEL_FLAGS variable,
this keeps MAKE_PARALLEL_JOBS intact regardless of depth of the job call tree.

vlib: add plugin override support

Allow a plugin to override (suppress loading of) other plugins. This
mechanism allows a developer to prevent specific plugins from being
loaded.

To do so, provide an "overrides" list in the plugin definition:

VLIB_PLUGIN_REGISTER () =
{
  <snip>
  .overrides = "avf_plugin.so,ioam_plugin.so,dpdk_plugin.so",
};

or some such. Simply list the plugins in question as shown above. The
.overrides structure member is limited to 256 octets. The named .elf
section mechanism used to discover the vlib_plugin_registration_t's
precludes the use of a variable-length array of strings.

Use the vlib log to eliminate plugin and built-in vat plugin loader
console spew.

Added vlib_log_register_class_rate_limit(...) to allow procedural
configuration of the log rate-limit. We *never* want to rate-limit
plugin loader messages.

stats: fix state counter removal

Avoid using vec_del1() for directory vector to keep indexes valid all
the time.

There are state counters for each slave in LACP bond mode which can be
dynamically created and removed. Vector index is used to access these
counters. But also vec_del1() is used to remove counter from vector.
This function changes the index of the last element, so after this we
are unable to access ex-last element using old index.

As a result it is not possible to add-del-add two interfaces to the LACP
bond:

DBGvpp# create bond mode lacp
BondEthernet0
DBGvpp# create packet-generator interface pg1
DBGvpp# create packet-generator interface pg2
DBGvpp# bond add BondEthernet0 pg1
DBGvpp# bond add BondEthernet0 pg2
DBGvpp# bond del pg1
DBGvpp# bond del pg2
DBGvpp# bond add BondEthernet0 pg1
DBGvpp# bond add BondEthernet0 pg2
bond add: /if/lacp/1/3/partner-state is already register
