Spinlock performance improved when implemented with compare_and_exchange
instead of test_and_set. All instances of test_and_set locks were refactored
to use clib_spinlock_t when possible. Some locks e.g. ssvm synchronize
between processes rather than threads, so they cannot directly use
clib_spinlock_t.

The vlib init function subsystem now supports a mix of procedural and
formally-specified ordering constraints. We should eliminate procedural
knowledge wherever possible.
The following schemes are *roughly* equivalent:
static clib_error_t *init_runs_first (vlib_main_t *vm)
{
clib_error_t *error;
... do some stuff...
if ((error = vlib_call_init_function (init_runs_next)))
return error;
...
}
VLIB_INIT_FUNCTION (init_runs_first);
and
static clib_error_t *init_runs_first (vlib_main_t *vm)
{
... do some stuff...
}
VLIB_INIT_FUNCTION (init_runs_first) =
{
.runs_before = VLIB_INITS("init_runs_next"),
};
The first form will [most likely] call "init_runs_next" on the
spot. The second form means that "init_runs_first" runs before
"init_runs_next," possibly much earlier in the sequence.
Please DO NOT construct sets of init functions where A before B
actually means A *right before* B. It's not necessary - simply combine
A and B - and it leads to hugely annoying debugging exercises when
trying to switch from ad-hoc procedural ordering constraints to formal
ordering constraints.

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

Instead of repeatedly cutting, pasting, and hacking to create a new
callback, use vnet_flow_rewrite_generic_callback(). Add three
arguments to the flow rewrite callback:
(in) pointer to an array of report elements,
(in) length of array,
(out) pointer to the stream index
Change existing code prototypes. Code owners encouraged to evaluate
whether they can use the generic callback or not, at leisure.
/* ipfix field definitions for a particular report */
typedef struct
{
u32 info_element;
u32 size;
} ipfix_report_element_t;
Best generated like so:
_(sourceIPv4Address, 4) \
_(destinationIPv4Address, 4) \
_(sourceTransportPort, 2) \
_(destinationTransportPort, 2) \
_(protocolIdentifier, 1) \
_(flowStartMicroseconds, 8) \
_(flowEndMicroseconds, 8)
static ipfix_report_element_t simple_report_elements[] = {
foreach_simple_report_ipfix_element

/* Set up the ipfix report */
memset (&a, 0, sizeof (a));
a.is_add = 1 /* to enable the report */ ;
