Test for new metadata at each packet
After sending each data packet in live, we need to check if new metadata
is available before sending the index informing the viewer it can read
the trace.
Since the data and the metadata are handled by two different threads,
this patch introduces a rendez-vous point: if new metadata is available,
the data thread flushes the metadata stream and waits on a conditionnal
variable. When the metadata thread finishes to send its data, it wakes
up the data thread which can send its index.
That way, the viewer is informed new metadata is available before
attempting to read a packet that might require an update of the
metadata.

Buckets with many entries encountered in a hash table could cause it to
grow to a large size, beyond the scope for which this mechanism is

the hash table grows to larger size, split-counter node accounting is
expected to deal with resize/shrink rather than relying on an heuristic
based on the largest bucket size.
This is fixing an issue where we see hash tables sometimes reaching 65k

Introduce configure --with-lttng-system-rundir

It does _not_ allow multiple instances of system-wide sessiond to run in

one single system-wide sessiond at any given time.

This value is only used for the sync_file_range, but it has to be set
