There were various races with the way metadata was handled for UST. Fix
this by:
- Ensuring that metadata cache is destroyed only when the metadata
channel is destroyed (it is already protected by refcounting).
- Ensuring that close_metadata() command (issued by sessiond) just
closes the stream wakeup_fd, and let the metadata management thread
(which has ownership of the metadata stream) perform the teardown.
- Ensure that switch timer, for metadata, is always stopped before any
of the metadata stream or channel teardown is done.

Fix: consumer metadata switch timer error handling
The thread handling the metadata switch cannot call
consumer_timer_switch_stop(), because it would become stucked waiting
for itself to execute the teardown signal handler.
Moreover, only one thread is allowed to call start/stop timer (by
design). Therefore, it's a race to have the thread handling the timer
handler calling "stop".
Fix this by adding a "switch_timer_error" flag, which just inhibits the
timer if an error is encountered, but does not modify its state
otherwise.

On-disk multiple tracefiles circular buffer
This patch introduces the tracefile_size and tracefile_count parameters
to the enable-channel command and the API.
This allows to split a stream into multiple tracefiles and limit the
amount of trace data to keep on disk. The tracefiles are readable
independently or with the others as long as the metadata file is
present.
For now only local traces are handled, relayd modifications coming soon.

UST periodical metadata flush
Add a socket between the sessiond and the ust-consumer to allow
periodical flush of the metadata channel.
If enabled (by specifying the --switch-timer option on the metadata
channel), a new timer thread in the consumer asks the session daemon for
new metadata for a specific session.
All the metadata collected is written into a metadata cache in the
consumer, this mechanism is useful for synchronisation (to avoid race
conditions between two metadata updates) and will also be useful when we
implement the snapshots.

Tests: Fix nprocesses applications shutdown
The nprocesses test is using the SIGPIPE signal to shutdown the spawned
child applications. This is done in order to silence the shell message
such as this one:
"nprocesses/test_nprocesses: line 79: 26458 Terminated"
This mechanism is broken on systems where the SIGPIPE default handler is
overriden (thus no application shutdown occurs) in the executing
environment. This could lead to stale applications polluting the system
and causing heratic behavior in subsequent tests.
This commit add a loop and check that all the spawned applications have
been successfully killed.
