Network streaming support
This is a huge commit integrating a lot of new feature for network
streaming support with the lttng-relayd previously merged.
Please note that this commit is the initial import of the network
streaming feature meaning that this is NOT stable and SHOULD be
considered experimental hence not suited for production deployment.
API Changes:
lttng_create_session_uri(), lttng_enable_consumer(),
lttng_set_consumer_uri() and lttng_disable_consumer() calls are added.
The lttng command line now supports these new calls by introducing two
new commands and one modified. (Please look at the --help option for
more details).
$ lttng enable-consumer
$ lttng disable-consumer
The "lttng create" command can now take new arguments to specify the
destination URI for network streaming. There is also a new flag which
allows the user to disable the consumer for the session.
At this point, the now old deprecated lttng_create_session() call is
still supported but SHOULD be replaced by lttng_create_session_uri().
More calls will be added to the API in order to facilitate the creation
of lttng URI.
Network streaming:
Both kernel and user space tracing are supported for network streaming.
For now, only IPv4 and IPv6 protocol over TCP is supported. Two network
socket are used where one is for control commands and the second one is
for data transmission. The port are respectively 5342 and 5343.
BUGS: Streaming high throughput traces (e.g lttng enable-event -a -k)
with low bandwitdh available to the relayd, the tracer does not behave
well when the metadata are not emptied enough quickly so data are
missing on the remote target and the tracing is simply not stoppable.
This is a known bug and future iterations will try to fix it.
WARNING: At this stage, there is _NO_ security features meaning no
remote authentication on the relayd, no transport layer encryption or
network secure handshake of some sort. So, uses only for in-vitro
experiment or on _trusted_ networks.

Fix: mmap write() for large subbuffers and handle EINTR (v2)
With large subbuffer (packet) size, if write() returns before copying the
entire packet for mmap buffers, the consumerd restarts the write
infinitely, which is not good at all.
This affects both lttng-ust (in default mmap mode) and lttng-kernel (but
only for mmap buffers, which is not the default).
This issue would show up with large subbuffer size.
We need to handle this case, as well as EINTR errors (which need to restart
write).
Also fixing the return value of mmap read functions, which were returning
the amount of data written by the last invocation of write() rather than
the total number of bytes written. splice use had the same issue.
Also now consider a write() that returns more bytes than requested as an
error.
Moreover, assigning error = ret after failed splice and write was a
mistake: error is holding the actual error value. ret just holds -1.

Fix: enable event with different loglevel error
This following example was NOT returning a correct error message.
"event1" is set with a loglevel "TRACE_CRIT". The normal behavior here
is that once enabled, you can not change the loglevel of the enable
event on the tracer side with a second command. It now returns a new
error message like so:
$ lttng enable-event event1 --loglevel-only TRACE-CRIT -u
$ lttng enable-event event1 --loglevel-only TRACE-WARNING -u
[...] Event already enabled with different loglevel
This commit makes the session daemon verify if _both_ the name and
loglevel are the same when enabling an event or else an error is
returned.
Also, the session daemon will continue enabling events and not return an
error is the loglevel does not match event for ust app on the tracer
which returns an EPERM at that stage. This is to address the case where
two applications have the same event name but with different loglevel.

Fix: work-around glibc __nptl_setxid vs clone hang
hash table resize threads exit end up setting a "locked" state within
libc pthread, which deadlocks with seteuid/setegid called from the
cloned process in runas.c when runas() is called exactly when a resize
thread exits.
Temporarily fix this issue by adding a mutex cross this resize
operation, which holds mutual exclusion with runas() usage.
We should investigate whether we want to properly call exec() from the
runas.c clone child before touching any non-async-signal-safe libc call.
However, given that this change is more intrusive, let's first use this

Fix consumer lttng_consumer_poll_socket poll revents check bug
Was causing the sessiond to fail to receive streams under heavy load,
because this test needs to be done with a mask rather than equality.
Testing equality was failing as soon as POLLPRI (or any other flag) was
set.

Fix: make lttng expand path for trace output opt
lttng create --output was passing the path string to the session daemon
and thus, for relative path like './mytraces', it was created in the
current directory of the session daemon.
Now lttng command line uses the realpath(3) of the --output string and
denies creation if multiple level of directory does not exist (Ex:
/tmp/foo/bar/chap, if foo/ does not exist, it is refused).
Directory creation still occurs on the session daemon side.

Improve tests and change tests/ directory layout
Add run-report.py and test_list.py files which are an extended test framework
providing memory and CPU sampling of the session daemon during the tests.
Tests are now divided on a per package basis. The kernel/ directory contains
integration tests for lttng-modules (kernel tracer). ust/ directory contains
tests for lttng-ust and tools/ directory has the unit tests of lttng-tools
itself which does not test tracer integration.
First patch aimed at improving test coverage of the lttng 2.0 toolchain and
provide the python framework for more detailled analysis.
Use make check to run them all or use run-report.py and select which tests to
run in test_list.py.
