The session lock is broken in that it does not handle teardown correctly
(use after free). Surround each usage by the session list lock for now
to fix this issue, and don't unlock the session lock after free. Since
each session lock usage is surrounded by session list lock, no other
thread will be left waiting on this lock when the session destroy is

Fix: make ust consumer posix compliant for poll flags
poll flags can have both POLLHUP and POLLIN set, which is not expected
by the consumer. Do not depend on this implementation-specific behavior.

Fix security permission on lttng run directory
Add execute flag for other (r+x) on the lttng run directory at
/var/run/lttng so instrumented application *not* in the tracing group

Fix documentation in lttng.h
Some functions in lttng.h are not aimed to be used only for kernel but
also for UST. This patch changes only the references made to 'kernel' to
make the documentation generic in the comments.

Fix: lttng UST and kernel consumer: fix ret vs errno mixup
- errno should be set to -ret (not the opposite!)
The main effect is that the perror errors were meaningless.
- errno should always be compared with positive values.
This was also causing consumerd error handling mistakes.
