Fix multi-session UST handling combined with shm fd teardown
shm fd is used as unique identifier for the channel when passing the
stream fds to the consumer. However, closing the fd reuses the same
identifier for the next round, thus getting the same consumer
channel/streams as the previous one. This causes multi-session tracing
to only work for the first session, not the following ones.
So instead of doing a channel lookup on add channel and a stream lookup
upon add stream, we "steal" the identifier. We still lookup the channel
identifier upon stream add though: this means the sessiond needs to keep
the channel shm fd open until it has finished sending all stream fds to
the consumer. For kernel consumer, the update operation still does a
stream id lookup.

ltt-sessiond: use short options for modprobe in order to support Busybox
Many embedded systems are based on Busybox, and therefore use the
Busybox implementation of modprobe. This implementation does not
support long options such as --remove and --quiet, only short options
such as -r and -q are supported.
This patches changes ltt-sessiond to use the short options, which are
more widely available, and allows lttng to work easily on a
Busybox-based system.

Preliminary work for full UST support
Add hashtable support for all UST data structure. At this point, enable
channel and event works with the global UST domain. The interaction with
the ust consumer has problems for now thus not working at this stage.
NOTICE: This commit does NOT work with the user space tracer yet. Please
refer to next commit for working version.
