Add src.text.dmesg component class
The new src.text.dmesg component class reads the standard input or a
specific file and converts each line to a CTF IR event, building the
appropriate metadata objects when needed.
This component does what babeltrace-log(1) used to do. The
babeltrace-log(1) application can be replicated as such:
dmesg | babeltrace -c src.text.dmesg -p read-from-stdin=yes \
--no-debug-info -o ctf -w /path/to/output
The component class's initialization parameters are:
`read-from-stdin`:
True to read the lines from the standard input stream (excludes
`path`).
`path`:
Path to the regular file from which to read lines (excludes
`read-from-stdin`).

ctf: notif-iter: pass current stream ID to get_stream() medop
Make the notif iter's get_stream() medop receive the current stream

appropriate stream ID which is only known dynamically after decoding the

Notifications of which the type is not known (if this component is used

notification.
You can use the `hide-zero` parameter (boolean) to hide the counts which

Automatically generate discarded packets/events notifications
This patch adds discarded packets and events notifications. Those
notifications are automatically generated by each notification iterator
by looking at packet header (PH) field's `packet_seq_num` and packet
context (PC) field's `events_discarded` fields to keep track of the
current state. Automatically generating those notifications, and
forbidding the user to create them, allows them to always be
synchronized with the values of the PH and PC special fields, and
guarantees to the user that they are generated whenever there is a
change in those values.
Each notification contains a count, an optional beginning clock value,
and an optional ending clock value, as well as a stream in which the
elements are discarded by the tracer.
As of this patch, flt.utils.trimmer does not reset the value of its
copied `packet_seq_num` and `events_discarded` fields to 0, and this is
probably a bug because a notification iterator on an flt.utils.trimmer
component can see discarded packets or events notifications before the
first packet beginning notification (which should not be the case if we
consider that a trimmed stream should act like a stream which originally
had those time bounds).
The sink.text.pretty component does not do anything specific with those
new notifications yet, but they are expected to be used to replicate
Babeltrace 1's behaviour (printing warnings).

ctf: remove strict metadata mode, update automatic CC mapping behaviour
Update the automatic mapping of specific fields to clock classes when
no explicit mapping is found in the integer field type to follow this:
| 0 CCs | 1 CC | 2+ CCs
--------------------------------------------------------------------
FT is mapped | Unreachable | OK as is | OK as is
FT is not mapped | Map to auto 1 GHz | Map to single CC | Error
The (FT is not mapped, 0 CC) cell follows Babeltrace 1's behaviour: when
a special timestamp field is found in the packet context
(`timestamp_begin` or `timestamp_end`) or event header (`timestamp`)
scope, when this timestamp field is not explicitly mapped to a clock
class, and when there's no clock class at this point in the trace, then
create an automatic, 1 GHz clock class and, in this case, name it
`default`. Map the field to this implicit 1 GHz clock class. See
section 8 ("Clocks") of CTF v1.8.2.
Cell (FT is not mapped, 0 CC) is a fix for old versions of LTTng, and
cell (FT is not mapped, 1 CC) is a fix for old versions of CTF writer.
Cell (FT is not mapped, 2+ CCs) is an error because we wouldn't know

Remove the concept of event class attributes
The concept of event class attributes could be confusing with the
eventual concept of user attributes to be introduced in CTF 2. This is
not strictly required for Babeltrace 2.0: we can create dedicated
accessors for CTF 1.8 attributes (ID, name, log level, EMF URI). This is
what this patch does, removing the attributes API and adding:
* bt_ctf_event_class_get_log_level()
* bt_ctf_event_class_set_log_level()
* bt_ctf_event_class_get_emf_uri()
* bt_ctf_event_class_set_emf_uri()
There are already accessors for the name and ID attributes. As to the
stream class ID (`stream_id`) attribute, it should never have existed in
the first place because you can always use the parent stream class's ID.
Thus this patch also fixes a bug where there was a synchronization
problem between a stream class's ID and the `stream_id` attribute of its
contained event classes.
The bt_ctf_event_class_get_log_level() and
bt_ctf_event_class_set_log_level() functions use the new
`enum bt_ctf_event_class_log_level` enumeration which contains all the
log levels of LTTng-UST, which happen to be CTF 1.8's log levels too
because Babeltrace 1 prints those names for those values whatever the
trace's producer. A translation is performed from the numeric values to
this enumeration in plugins/ctf/common/metadata/visitor-generate-ir.c,
and the reverse is done in plugins/text/pretty/print.c. Knowing this,
the `loglevel_string` attribute that visitor-generate-ir.c used to add
to event classes (and which plugins/text/pretty/print.c used to
pretty-print the names) is removed. This was also an issue because
Babeltrace 1 does not know `loglevel_string` and sink.ctf.fs, through
the CTF writer implementation, was serializing this attribute in the
generated metadata.
tests/lib/test_ctf_writer.c is updated to test the individual accessors
instead of the generic attribute API.
plugins/libctfcopytrace/ctfcopytrace.c is updated to copy the known
attributes intead of using the generic attribute API.

ctf: add metadata decoder config. and `strict-metadata` param in src.ctf.fs
The common metadata decoder now accepts an optional configuration
structure. The offset (seconds and nanoseconds) to apply to all the
clock classes is found in there, as well as a new option which makes the
decoder strict. In strict mode, the decoder does not allow the decoded
metadata stream to be off semantically. For example, in strict mode,
clock classes named `monotonic` are not forced to be absolute when it is
detected that the stream was produced by an LTTng tracer.
It's not expected that the strict mode be something that any user would
want under normal conditions because the non-strict mode fixes errors
made by known tracers to make things work for the other components of
the graph. As such, there's no quick --strict option in the CLI's
`convert` command: the user can instantiate its own source.ctf.fs
component with --component for this and pass the options with --params:
babeltrace -c src.ctf.fs --path ~/my-traces/trace -p strict-metadata=yes
I'm also fixing the parameter names and types for the clock class
offsets, both in the CLI and in source.ctf.fs, so that all the project's
modules are in sync regarding this. The parameters are now
`clock-class-offset-s` and `clock-class-offset-ns`, and with the
`convert` command, they are set with resp. --clock-offset and
--clock-offset-ns. They used to be passed to the `run` command as string
values (using --key and --value), but now they are part of the
component's --params option so that they are recognized as constant
integer values (even if negative).

cli: add global --log-level option
This new global option (applies before the command name) sets the
default log level of all the known (project's) loggers. This default
log level can still be overridden by a specific environment variable,
for example:
BABELTRACE_PLUGIN_CTF_METADATA_LOG_LEVEL=D babeltrace --log-level=I ...
In this example, all the log levels are set to INFO, but
BABELTRACE_PLUGIN_CTF_METADATA_LOG_LEVEL overrides the `ctf` plugin's
metadata module's log level to DEBUG.
When you don't specify --log-level, it defaults to W (WARN), the current
behaviour.
--verbose is now the equivalent of --log-level=I, and --debug is the
equivalent of --log-level=V. --verbose and --debug do the same thing,
for the `convert` command, whether they are global or specific to the
command. --verbose and --debug can still be specified together, and
whatever the order, the lowest log level always wins: VERBOSE.
The --log-level option can override previous --verbose, --debug, or
--log-level options because it didn't exist in Babeltrace 1 anyway so
there's no way to break backward compatibility:
babeltrace --log-level=W --verbose --log-level=E ...
In this case, the final log level is ERROR.
Other example with implicit `convert` command:
babeltrace --log-level=E /path/to/trace -v
In this case, the command's --verbose option sets the log level to
INFO because it's lower than ERROR (set by --log-level=E).
One of the main use cases of the new --log-level option is to completely
disable logging:
