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.

catch warnings in the tracepoint headers when they are installed in the

A side effect is that it causes problems on some system where the system

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.

Move internal headers to 'src/' dir
Move internal headers from the global 'include' directory to their
respective private directories under 'src/'. Remove the 'ust-' prefix
when appropriate as they are now included with the 'common/' path which
makes it easier to distinguish public and internal headers.

Add 'src' dir to global include path
The objective is to move internal headers from the global 'include'
directory to their respective private directories under 'src'.
Move the private generated 'config.h' to 'src/common/config.h', this way
it can be include with 'common/config.h' and reduce the risk of clashing
with a similarly named file.
