API refactoring: introduce probe context
Introduce a "probe context" to allow passing the "ip" context from the

Also fix signedness of the return type of the get_value context

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

Fix: perform lazy initialization of getenv common lib
The ust-dl wrapper ends up calling into the getenv common lib very early
from library constructors through use of dlopen by the tracepoint
instrumentation code.
This happens before the getenv common lib is explicitly initialized by
liblttng-ust's contructor.
Perform lazy initialization for those early use by constructor
scenarios.

fix: remove unused include wait.h
We moved our internal 'wait.h' to 'common/wait.h' but forgot the include
in 'lttng-events.c'. This was a stale include as we don't use anything
from wait.h here. On Linux this went unnoticed as there is a system
'wait.h' which is an alias for 'sys/wait.h'. However, there is no such
system header on FreeBSD and it results in a build failure.
