lttng-live input plugin
This new input format allows Babeltrace to connect a lttng-relayd and
attach to a running live session.
In order to use it, you need to create a live session (refer to LTTng
documentation for that) and then :
babeltrace -i lttng-live net://hostname
Where hostname is the hostname or IP address of the lttng-relayd
receiving the live trace.
When you do this command, it will list the active sessions on the relay.
To attach to a particular session, redo the same command, but add after
the hostname the session ID of the session you want to read.
For example, to attach to the session 42 :
babeltrace -i lttng-live net://hostname/42
If you want to know what is going on in the background, you can add the

Live: let read API detect inactive streams, allow streams without fd
In live streaming, there are cases where a stream will be inactive from
beginning to end and so will never call bt_iter_next. For those cases,
we have to detect when we are reading an inactive stream which happens
when all other active streams have been closed.
We don't want to have the same checks in two places, so this fix removes

The "no-as-needed" is only needed for plugins, not for libraries we

Fixes in babeltrace core to support non-CTF traces
Since we will have an effort soon to cleanup the Babeltrace plugin
mechanism, this patch adds just the bits required in Babeltrace to not
crash if a non-ctf is opened. We also add the support of net:// URIs.
That way, an input plugin can just implement the open_trace callback
and process its own input trace without requiring a CTF iterator.

Fix: reversed logic in packet vs content size
As described in CTF section 5.2
"If the packet size field is missing, the whole stream only contains a
single packet. If the content size field is missing, the packet is
filled (no padding). The content and packet sizes include all headers."
Here is the correct semantic:
* Content size and packet size are available:
Packet is filled with data up to content size, and then with padding
up to packet size.
* Content size available, no packet size field:
The stream has a single packet. It is filled up to content size, and
the rest is padding.
* Packet size available, no content size field:
Packet filled completely, no padding.

in the "index" folder), we open it and use it instead of generating
the index at open.
