Fix: destroy session removes the default config file
Destroy session command by default removes the default config file
without checking the current session. As a result when we call any
other command which expects a default session by calling

This patch will fix this by checking that the default config file gets
removed only when destroy session is called with the current session.

man pages: use standard NAME format
As per man(7):
The only mandatory heading is NAME, which should
be the first section and be followed on the next
line by a one-line description of the program:
.SH NAME
item \- description
It is extremely important that this format is followed,
and that there is a backslash before the single dash
which follows the item name. This syntax is used by the
mandb(8) program to create a database of short
descriptions for the whatis(1) and apropos(1) commands.
Furthermore (lexgrog(1)):
When using the traditional man macro set, a correct NAME
section looks something like this:
.SH NAME
foo \- program to do something
Some manual pagers require the ‘\-’ to be exactly as shown;
mandb is more tolerant, but for compatibility with other
systems it is nevertheless a good idea to retain the
backslash.

Fix: deadlock between UST registry lock and consumer lock
Reorganize locking of ust registry and consumer socket communication.
commit
ce34fcd0 "Fix: per-uid flush and ust registry locking" attempted
to fix locking related to the UST registry, but doing so introduced a
deadlock. The actual solution is to reverse the order in which the UST
registry and the consumer lock nest: the UST registry will now to
responsible for serializing the registry content, and the consumer lock
will only protect communication with the consumer, as it should. This
deals with a TODO in the code.
The reason why this was not done from the beginning is that there was
originally an intent to make sure the ust registry lock is not held for
a long time, thus not while communicating with the consumer daemon.
However, when live has been implemented, it required communication with
the consumer daemon while the ust registry is held anyway. Therefore,
there is not much point anymore in trying to make sure this lock is not
held across the communication with consumerd in push_metadata. This
allows us to greatly simplify locking of the UST registry.

Fix: grab more than one packet for snapshots
There are a few issues with snapshot size: when taking a snapshot
without specifying any "max size" (should be unlimited), only a single
packet from each stream is saved. We expect all stream available content
to be saved. There is a similar issue when a max size is specified.
Also, trying to make all streams save as much data has unexpected
corner-cases: for instance, if we have this configuration:
- kernel channels: 2 subbuffers of 1MB x 8 CPUs
- per-PID UST channels: 16 subbuffers of 4kB x 8 CPUs x 100 apps
would require the user to have a very large max size, since it would try
to fit (8 + (100 * 8)) * 1MB = 808MB of sub-buffers, else it would fail.
This issue here is using the largest subbuffer size as the criterion
applied to all channels.
We fix those issues by simplifying the algorithm used to calculate how
much data to grab. Rather than calculating the size to grab from each
stream, we calculate a number of packets to grab. It fails if we cannot
grab at least one packet from each stream in the session. Then checks if
it can grab 2 packets from each stream, and so on, until there is no
more space available (based on max size). This is not a perfect
solution, but has the merit of being simple to understand, and has no
(or few) unexpected corner-cases.

Fix: per-uid flush and ust registry locking
Commit
c4b88406 "Fix: ust-app: per-PID app unregister vs tracing stop
races" introduces a regression for per-UID flush. It can be triggered by
the test_high_throughput_limits (root regression) test. For per-UID
tracing, we need to use the registry channel ID, not the per-application
channel ID, when asking the consumer daemon to flush.
When doing this fix, we notice that the locking rules of push_metadata()
are weird. A per-ust app session lock is protecting registry data, which
makes it impossible to call push_metadata from a ust session level (for
the entire session) in the case of per-UID tracing. Moreover, it's
unclear how holding a per-application lock can protect a registry shared
across applications in per-UID tracing. Therefore, we move all accesses
to the registry metadata_key and metadata_closed fields into the
registry lock critical section. We now only rely on RCU to ensure
existance of registry across push_metadata(), rather than relying on the
per-application session lock.
It also takes care of a documentation vs code mismatch: push_metadata()
documents that "The session lock MUST be acquired here before calling
this.", but in reality, it's the application session lock which is held
across those calls. Removing this requirement, and relying on RCU
instead, fixes this mismatch.
