Initial work for kernel tracing support
This commit adds trace kernel support to the complete set of tools. It
is working with the LTTng 2.0 and output traces readeable by babeltrace.
Quick changes log below:
Add multiple debug statement and bug fixes.
Add kernel trace directory creation.
Add kernel structure teardown.
Start kconsumerd on create session.
Start kconsumerd thread after exec.
Following up this commit, there will be a huge cleanup because a lot of codes
was added to make it work but it's not necessarily clean code structure.

Major changes of command processing for sessiond

5e16da05 by me and Mathieu
Desnoyers about the command processing using a command context.
This patch introduce a command context data structure which contains all

daemon from the lttng client.
The entire session daemon is refactored with this addition. All

removed and is now in the command context struct. Some of the functions
for the buffer allocation are removed/changed.

Major changes for the daemon data transmission
This commit reengineer the data transmission from the session daemon to
the liblttngctl. Instead of sending a packet on a per data structure
basis, this scheme uses lttcomm_lttng_msg structure has a header control
structure adding the payload_size to it. The payload data is then
appended after and only one send() is used.
This will permit AF_INET socket scaling for future development.
List sessions and list apps command has been modified to fit this
change.
In the meantime, some unuse code is removed and minor cleanup.

Add lttngerr support to ltt-sessiond
Now using the lttngerr API for message/error printing.
Also add the quiet option to the ltt-sessiond. The lttng auto spawn
session daemon option was also modified to use that quiet option to not
to pollute stdout when that spawned daemon is killed.

Add support for session daemon auto spawn
The lttng tool now spawns a session daemon if no ltt-sessiond is
running. Two new options added to control this behavior.
Introduce --sessiond-path and --no-sessiond to lttng command line tool.
Add --sig-parent to ltt-sessiond that sends a SIGCHLD to the parent pid
when the daemon is ready to process client command.

Change client message processing
ltt-sessiond can now send multiple response to the client for only one
command.
The list traceable apps command was modified accordingly to that
modification and now send one response per pid.
The liblttnctl was also changed to handle multiple reply and the
recvfrom_sessiond internal function is added removing the recv from the
ask_sessiond() function. Fine grained control helps.
