Instead of enforcing a "strict" release of data, which relies on
frequent rescheduling of sessions, allow some pacer coalescing, i.e.,
short bursts, that can minimize load on scheduler/session layer and
potentially leverage tso.

For some reason clang does not support &((struct foo*)0)->field in
static assertion contrary to gcc.
Use offsetof() macro implementation provided by both compilers instead.

* Avoid doing expensive bit extraction for most likely case where bucket
.log2_page_size == 0 and .linear_search == 0, saves 3-5 cycles for
lookup, data_prefetch and add operation
* use bextr instruction when available (x86 BMI instruction set)

Direct Verb allows for direct access to NIC HW rx/tx rings. This patch
introduce TX direct verb support for Mellanox ConnectX-4/5 adapters.
'dv' mode must be explicitely selected at interface creation to benefit
from this.

This is first part of addition of atomic macros with only macros for
__sync builtins.
- Based on earlier patch by Damjan (https://gerrit.fd.io/r/#/c/10729/)
Additionally
- clib_atomic_release macro added and used in the absence
of any memory barrier.
- clib_atomic_bool_cmp_and_swap added

It is much cheaper to use ctzll than to do shift,subtract and mask
in likely case when we are looking for 1st set bit in the uword.

Use this macro to arrange init function ordering between friend
plugins. Fails in the usual manner if the plugin doesn't exist, or if
the init function symbol is AWOL.
clib_error_t *
thisplug_init (vlib_main_t *vm)
{
clib_error_t *error = 0;
if ((error = vlib_plugin_init_function ("otherplug.so", otherplug_init)))
return error;
<etc>
return error;
}
VLIB_INIT_FUNCTION(thisplug_init);
