bt_ctf_clock_value_create(): freeze clock class

This is how other classes in the library work: when you instantiate a
class as a value (here a clock class as a clock value), the class is
frozen.

This patch does not seem to break the tests or change anything to the
CLI and plugins, which means all clock classes are already configured
before clock values are created out of them.

Graph: pass remove listeners when adding listeners

With this patch, when you call bt_graph_add_*_listener(), you can also
provide a "remove listener" which is called when the added listener is
removed when the graph object is destroyed. This is useful when you
dynamically allocate data only for the listener to add and you are not
the only owner of the graph object: the remove listener is where to
free/release this data.

Existing CLIs and tests are modified to match this change.

Fix: ctf: notif-iter: error on empty events (0 bits of data)

Do not create an event which consumed 0 bits of data stream: log an
error and return without creating it. We keep the buffer position at the
beginning of the last decoded event header, and we compare to the
current buffer position: if they are the same, then we consumed 0 bits
of data. It is possible, when we compare, that notit->buf.last_eh_at is
-1ULL (reset when requesting bytes from medium): in this case, we know
we requested bytes anyway, which means we consumed something to get to
this starvation point, thus the event is not empty.

ctf: notif-iter.c: check state on BT_CTF_NOTIF_ITER_MEDIUM_STATUS_EOF

When the notif iter's request_bytes() medium operation returns
BT_CTF_NOTIF_ITER_MEDIUM_STATUS_EOF, make sure that the notif iter
instance is in an expected state. Which states are valid depend on the
metadata (is there a packet size or not, etc.). Return an error from
request_medium_bytes() when the state is incorrect.

This solves streams which should fail but pass, for example when the
data ends within the middle of a packet header field, a packet context
field, or an event.

Cleanup: bison and flex detection

The previous detection code was quite convoluted and required to have
two variables set to the same value to work. For example, the lexer in
autotools is configured through the LEX variable, even if we require a
specific implementation we have to use it and base our detection code on
it.

The situation is now :

  - the FLEX and BISON variables are ignored.
  - the LEX and YACC variables need to be set if required like before.
