Pre-assign fixed loglevels
Some early LTTng-UST adopters brought to my attention that the way
tracepoint loglevels are currently specified in LTTng-UST might be too
relax for its own good. If each application define their own loglevel
names/values, it will become difficult to use the loglevels to select
"trace verbosity" in a system-wide manner.
Now that I come to think of it, it might make sense to pre-define a set
of supported loglevels, similarly to syslog(3). However, given that
tracing sometimes targets debug levels that are more fine-grained than
in the case of logs, I would propose to split the "debug" loglevel into
sub-categories.
My current thought is to simply just allow these loglevels. I doubt that
letting application developers specify extra loglevels on top of this
would be that useful, and it would certainly be more confusing.
In the list below, lower numbers means "low verbosity", higher numbers
means "high verbosity, debug-style information".

Force 64-bit timestamps
commit
9080554ff25b08f48762d2ee7cfa3981317e9c1d attempted to fix the
timestamp problem by using large event headers. It incorrectly stated
that those headers "use a 64-bit timestamp field". In fact, they use a
32-bit timestamp field (not 64). So they were helping (it was better
than using a 27-bit field), but the problem could still appear. It's
only when the RING_BUFFER_RFLAG_FULL_TSC is set that the ring buffer
forces use of the 64-bit fields.
Fix this for good by setting this flag.

Split liblttng-ust into liblttng-ust and liblttng-ust-tracepoint libs
So tracepoint.h (in applications) can just dlopen
liblttng-ust-tracepoint without having to load the full liblttng-ust.
Now liblttng-ust is only needed by tracepoint probes.
This is a first step to fix the deadlock between the dynamic linker
mutex and ust mutex occurring when liblttng-ust is dlopened (due to lazy
symbol resolving of Thread-Local Storage (TLS)).
Discourage dlopen of liblttng-ust (and of tracepoint probes) in the
README.

Make dlopen more robust by using the .0 target for the library
We've experienced a double library load on a setup where the lttng-ust
.so and .so.0 were two physical files instead of a symlink (as they
should be). So let's make liblttng-ust slightly more robust by
specifying the target .so.0 instead of .so. It will also make handling
of library version upgrades easier.

Rename liblttng-ust-malloc to liblttng-ust-libc, update to lttng-ust 2.0
- includes a fix to tracepoints to disable the tracepoint sites upon
unregistration of the library. This is useful for cases where, like
the libc wrapper, the library dependency for constructor/destructor
is not quite right due to cross-dependencies (lttng-ust depends on
malloc/free). This ensures the session teardown will never be in a
position where it could teardown data structures still in use
by probes that cannot be unregistered because their associated
library would already have called its destructor.
