Revert "Simplify create_session of lttng create command"
This reverts commit
318e4c832cc9a4209dcea885ef2a66cfd16f99d2.
The create_session function was changed making the session name not
having the date and time append to it anymore. This completely broke the
default behavior of automatic session creation. Only one possible
session name was 'auto'.

The internal UST ABI/API (used when lttng-ust is disabled) was not

Add UST version validation
Upon registration of an UST app, we now check the version compatibility
with the session daemon and set a compatible bit. Only the major version
is validated since major version bump implies ABI/API breakage.
For now, every action on the application list check the app compatible
bit before executing it. We are too close from a stable release so hard
*not standard* check is done across the map for ust-app. The downside is
that the client will not get informed of any incompatible app upon any
action on the tracer using lttng cli.
If the version is NOT compatible, the register done is sent and the app
is kept in the registry. We can't close the socket or deny the
registration because if the env. var LTTNG_UST_REGISTER_TIMEOUT=-1 is
set on the app side, infinite loop will occur and possibly stall the
app.

Split and remove lttng-share header file
This header is split into two files: defaults.h and macros.h.
A third header is introduce here which is common.h including runas.h and
macros.h which are part of the common library. Since the defaults.h
contains only defaults values, it seems ok to keep it seperate from the
common library having only macros and function calls.

Complete change of the source directory tree
For the sake of clearness and awesomeness :P, this change was needed for
better semantic across the code and better organization of source files.
src/
--> Contains source files of the project
bin/
--> Contains every binaries this git tree builds (lttng,
lttng-sessiond and lttng-consumerd).
lib/
--> Contains exported libraries (lttng-ctl).
common/
--> Contains shared code for the entire project. (internal
libraries mostly)
Every internal headers are moved from include/ to src/common. The
include directory only contains exported public headers now
(lttng/lttng.h). The -I$(top_srcdir)/src is also added for all
Makefiles.
The consumerd APIs are not exported anymore. The reason is that the
consumer will get completely re-engineered in the next months. It's our
safety net for the APIs breakage of the coming year concerning the
consumerd library.
Renaming is done also on some internal libraries to follow the naming
convention. The public library liblttngctl is renamed to liblttng-ctl
making it linkable now with "-llttng-ctl" deprecating the old
"-llttngctl".
No code is changed with this commit except #include statements
added/removed/renamed. This is why there is yet files and internal API
calls that does not follow the naming convention (Ex: lttngerr.h,
lttng-share.h in src/common).

Fix double free and out of order delete session
Failing to create metadata, the data structure was freed but the pointer
was not set to NULL. When deleting the metadata of that session (that
has failed), the pointer was not NULL creating a "valid" pointer for the
check and creating a double free error. This failure happens when the
session daemon reached the maximum number of open files.
Also, on destroy trace, the ust app session was freed and deref. just
after creating an invalid pointer access.
Finally, set the started flag of a ust app session to 0 when stopping
the session.

Add UST test for n events using validation
ust-nevents tests an instrumented application generating 100 events and
validating that those events are found using babeltrace (need to be
installed).
Adds the tests/utils.sh which is a family of function used to interact
with lttng cli. There is also a trace_matches function which uses
babeltrace to find string patterns.
Also, the session daemon is spawned at the beginning of runall.sh and
killed at the end. This means that all tests are done on a single
session daemon instance. Thus, session name across tests have to be
unique! From now on, each test should use the file name as a unique
identifier for the session name.
Finally, fixed the session name for all tests. At this commit, "make
check" or "sudo make check" should pass.
