sessiond: Add --extra-kmod-probes option
This patch adds the --extra-kmod-probes option to lttng-sessiond. The

The option specifies a list of extra probe kernel modules to be loaded
(and unloaded) by lttng-sessiond. The list is appended to either the
default list or to the user-supplied --kmod-probes list.
This option is especially useful for kernel developers who need the
default LTTng kernel probes plus additional probes in order to
instrument their custom kernel or module. This becomes easy with
--extra-kmod-probes:
lttng-sessiond --extra-kmod-probes=custom_subsys,other

Not parenthesizing the clauses in a filter string causes JUL events to be

issued with a filter and the --loglevel-only option.
For instance,
lttng enable-event -j "my_event" --loglevel-only JUL_CONFIG -f "int_loglevel > 0 || int_loglevel < 0"
results in the following filter being applied:
int_loglevel > 0 || int_loglevel < 0 && logger_name == "my_event" && int_loglevel == 700

content.
- Introduce LTTNG_TOOLS_BUILD_GIT_SOURCE automake conditional rather

do not invoke "git describe" when configure --disable-git-version
has been requested.
- Use git describe rather than git describe --long --all. Based
on the last tag, and adds the first numbers of git revision.
Last tag is useful both to the developer and in a bug report,
whereas the branch name returned by --long --all is meaningless

- We want to ship version.h.tmpl in the tarball (make dist), not
version.h which is generated. Someone could very well do a
git init on the extracted tarball and want to have git tracking

Mi: mi backend + mi for command version
The machine interface option is now available for version. Other
commands will shortly follow. Mi backend is expected to grow with
addition of mi support to other commands.
How to use:
lttng --mi <mi_output_type> <command>
This syntax will be the same for all commands. Currently *only xml is
supported as machine interface output.*
As for errors handling, if an error/warning occurs while using mi it
will be reported on stderr as normal. The integrity of the mi output
cannot be guaranteed if an error/warning occurs. The error output format
is consistent and easy for a machine client to parse. Thus no mi output
format is required for error output.
Example:
lttng --mi xml version
Output:
<?xml version="1.0" encoding="UTF-8"?>
<command>
<name>version</name>
<output>
<string>2.4.0-rc2</string>
<major>2</major>
<minor>4</minor>
<patchLevel>0</patchLevel>
<name>Époque Opaque</name>
<description>The Époque Opaque is a black IPA from Trou du Diable
brewery. The nose is eerily reminiscent of the coffee crisp candy from
of our childhood. These strong mocha accents are present on the palate,
which are quickly subdued by Japanese and Australian hops leading to a
final state of satisfaction enjoyable for any fan of bitter
beer.</description>

Fix: validate file path creds in autoload mode
Validate the credentials only when in auto load mode for the auto/
directory. The lttng load command now checks the session file creds and
validate if it's readable before trying to do so.
Thus with this, a user can load a session from the system wide directory
as long as she/he has the rights to read it.
