Fix: Discard disable event command filter payload
liblttng-ctl sends both the filter expression and filter bytecode
whenever lttng_disable_event_ext() is used _or_ when it is used
implicitly by lttng_disable_event() on an Agent domain (Log4j,
JUL or Python).
As of now, the session daemon ignores this filter payload.
However, on some rare occasions (the frequency of which depends
on the system's configuration and load), the second call to
sendmsg() done by liblttng-ctl could block and return an error
when the session daemon closed the socket (EPIPE).
This fix ensures the payload is received and discarded by the
session daemon, which in turn allows the client to handle the
session daemon's reply to the command.

Fix: clean-up agent app hash table from the main sessiond thread
The agent application hash table, which is allocated by the session
daemon's main thread, is free'd from the agent application registration
thread.
This leads to a number of interesting scenarios under which the agent
app registration thread may encounter an error, thus tearing itself down
and freeing the agent_apps_ht_by_sock hash table. Of course, nothing then
prevents the client processing thread from accessing this invalidated hash
table to list, enable or disable agent events which leads to crashes or
assertions hitting in ht_match_reg_uid().
However, it is not necessary for the agent app registration thread to
encounter an error for this to prove problematic. As shown in bug #893,
the session daemon's teardown will assert on a NULL key in
ht_match_reg_uid() whenever it is performed while a JUL, Log4J or Python
event is still enabled in a session. This happens because the session
daemon's clean-up triggers the destruction of all sessions. The destruction
of those sessions would access the free'd agent_apps_ht_by_sock to disable
the registered agent events.

Fix: handle sys_futex() FUTEX_WAIT interrupted by signal
We need to handle EINTR returned by sys_futex() FUTEX_WAIT, otherwise a
signal interrupting this system call could make sys_futex return too
early, and therefore cause a synchronization issue.

Fix: metadata push -EPIPE should be recoverable
This return value can be caused by application terminating concurrently
(when using per-PID buffers), so it should not make the consumer
management thread exit.

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
get_session_name() function, it fails.
This patch will fix this by checking that the default config file gets
removed only when destroy session is called with the current session.
