Fix: don't abort metadata push on closed metadata
The failure/exit of any of the consumerd, relayd or applications
(in per-PID buffer mode) will cause the metadata closed flag to
be set.
While pushing new metadata updates to the consumerd (and relayd
in streaming/live scenarios) will fail, those conditions should
be handled in-place.
Applications are _expected_ to exit during the course of a per-PID
session. However, they will typically have pushed their metadata
to the metadata cache before doing so. The session daemon must
flush the unconsumed metadata to the consumerd in this case.
Failure to answer to the metadata request originating from the
consumerd can cause it to keep the stream lock held and, thus,
prevent the channel poll thread from cleaning up on channel
close.

Fix: consumerd: order of metadata cache vs stream lock
The locking order comment in consumer.h is incorrect. First, its
description of locking order is not in sync with the comment found in
consumer-metadata-cache.h. The comment in struct consumer_metadata_cache
only states that the metadata cache lock nests inside the consumer_data
lock, and does not mention the stream lock, which implies that the
metadata cache lock does NOT nest inside the stream lock. But let's
investigate further to confirm:
* lttng_consumer_read_subbuffer() acquires the stream lock, and then
calls lttng_ustconsumer_read_subbuffer() with stream lock held,
and then invokes commin_one_metadata_packet(), which acquires the
metadata cache lock.
* lttng_ustconsumer_sync_metadata() acquires the metadata stream lock,
and calls commit_one_metadata_packet(), which takes the metadata cache
lock.
Therefore, update the comment in consumer.h to state that the metadata
cache lock nests INSIDE the stream lock, and update
consumer_del_metadata_stream() accordingly.
This should take care of fixing the locking order reversal found by
Coverity.

generate a ctf index 1.0 index file layout.
If both relayd and consumerd versions are 2.8+, then we can send the ctf

doc/man: only require asciidoc-attrs.conf when building the man pages
Situations:
* If you want to and can build the man pages:
* If it's a tarball tree:
* Make the man page destinations depend on asciidoc-attrs.conf.
Since it's a generated file, its date is greater than the
date of the prebuilt man pages, therefore the man pages are
built again, which is a good thing because they include the
default values of this build.
* If it's a Git tree:
* Always build the man pages anyway (no prebuilt man pages here).
* If you want to, but cannot build the man pages:
* If it's a tarball tree:
* Make the man page destinations NOT depend on asciidoc-attrs.conf,
because its recent date would ask said destinations to be rebuilt
and this is not possible because we don't have the tools.
However, warn the user at configure time that the prebuilt man
pages will be installed, which means that they will contain the
project's default values, not this build's default values.
* If it's a Git tree:
* Not valid: error at configure time as usual.

Create a dedicated test suite for Perf
Introduce the perf_regression test suite that must be run manually to
check if the support for the Perf-related features are available on the
current machine. This test cannot be run automatically since there are
some platforms where it can fail (VMs, some SoCs, etc).
For now, the test only makes sure that we can trace events with perf
contexts enabled by raw ID in kernel and user-space. The test only works
if libpfm is installed on the system and fails if it is not installed.
