Refactoring: tracepoint: allow explicit tracepoint instance provider name
Add a template_provider argument to LTTNG_UST_TRACEPOINT_EVENT_INSTANCE
to allow a tracepoint instance to refer to a tracepoint class from
another provider within the same compile unit.
Also introduce struct lttng_ust_tracepoint_class to clearly split the
event instance from the class, thus allowing the event instance to refer
to the class through a single symbol. This removes the need to rely on
LTTNG_UST__TP_ARRAY_SIZE() to calculate the size of the event field
array (part of the class) from within the event instance. This
refactoring opens the door to have event class and instance not only in
different providers, but also in providers emitted within different
compile units and shared objects in the future.
For instance, if a .c includes the following headers:
#define LTTNG_UST_TRACEPOINT_CREATE_PROBES
#include "a.h"
#include "b.h"
where a.h contains:
LTTNG_UST_TRACEPOINT_EVENT_CLASS(a, myclass,
LTTNG_UST_TP_ARGS(int, anint),
LTTNG_UST_TP_FIELDS(
lttng_ust_field_integer(int, intfield, anint)
)
)
and b.h contains:
LTTNG_UST_TRACEPOINT_EVENT_INSTANCE(a, myclass,
b, myeventinstance,
LTTNG_UST_TP_ARGS(int, anint)
)
This is a localized API-breaking change introduced very early in the
2.13-rc cycle.
This changes the ABI exposed by the probe providers, so bump the probe
provider major version, and make newer lttng-ust reject old incompatible
major. We can do this because it is very early in the 2.13-rc cycle.

sequence type: use previous field for length if length_name is NULL
A common use-case for sequences is to use the field located immediately
prior to the sequence as sequence length.
The fact that the sequence type needs to explicitly contain its length
name ties the sequence type to where it is placed within the structure
fields, preventing re-use of the sequence type.
In order to reduce the memory footprint of the field descriptions and
allow re-use of common field types, special-case the NULL length_name to
use the field prior to the sequence as length.
This allows more efficient type descriptions without reducing the
overall flexibility of sequence layout.

Tracepoint API namespacing 'TP_ARGS'
The ABI bump gives us the opportunity to namespace all public symbols
under the 'lttng_ust_' prefix. Namespace all API symbols and macros
under 'lttng_ust_' / 'LTTNG_UST_' and add compat macros to keep
compatibility with the previous API.

Introduce API compatibility macros
Introduce API compatibility macros, allowing to compile-out backward
compatibility for older API major versions.
The initial use-case introduced here is renaming of the tracepoint(),
do_tracepoint() and tracepoint_enabled() macros to add the lttng_ust_
prefix. The old macros are only defined when API compatibility with
soname 0 is enabled.

tracepoint: split provider and event name
Now that we bump the ABI, it's a good opportunity to split the
tracepoint "name" field, which is a concatenation of
#provider_name ':' #event_name
into separate provider and name fields.
Reject tracepoints and callsites which are larger than the maximum
length supported by LTTng-UST rather than silently truncating them.
This emits a warning visible with LTTNG_UST_DEBUG=1 to allow pinpointing
erroneous users.
Note that as long as tracepoints are defined statically with the
tracepoint API, the length of the provider and event names is validated
with a build-time check.
This means the core of tracepoint.c is now agnostic to the length of the
tracepoint provider/event name. If there is ever a change to the
LTTng-UST protocol allowing larger length for those, changing the
length validations will be straightforward.

Remove -Wsystem-headers from tests
The objective of add -Wsystem-headers to the tests Makefiles was to
catch warnings in the tracepoint headers when they are installed in the
compiler system header path. However the tests are always built against
the headers inside the tree which are not in the system header path.
A side effect is that it causes problems on some system where the system
headers generate warnings and thus prevent us from building with
warnings treated as errors.

Initialize liblttng-ust-common in dependent libraries
liblttng-ust-common is a new public library introduced in this
developement cycle to contain the shared state between liblttng-ust and
our other libs that can't link directly on liblttng-ust. The constructor
of each of these libraries should now call the liblttng-ust-common
constructor early in their own constructors to ensure proper execution
order.
* Rename library constructors with the _ctor suffix to help
distinguish them from other _init functions.
* Hide the fd-tracker init fonction, the liblttng-ust-common ctor
should be called instead.
* All libraries linked on 'liblttng-ust-common' call its constructor
early in theirs.

tracepoint: validate provider/event name length with static assert
Validate the provider/event name length with static assert in both
_DEFINE_TRACEPOINT() and within the tracepoint probe.
Validating the length in _DEFINE_TRACEPOINT() ensures that the
tracepoints don't try to register a callsite with a too long name by
mistake. This will enable handling of too long names with rejection of
the tracepoint rather than truncation of the name in a future patch.
The tracepoint probe was already validating the length, but using a
static assert makes the error message clearer.
Introduce LTTNG_UST_TRACEPOINT_NAME_LEN_MAX which is separate from the
communication protocol's LTTNG_UST_ABI_SYM_NAME_LEN to ensure both
communication protocol and instrumentation API can evolve independently.
