jolavillette 0442e59411 GXS: add opt-in profiling of the message loading path
Loading a channel with a few thousand posts takes ten seconds or more, and
the cost is spread over four layers with no way to tell which one dominates:
SQL retrieval in RsDataService, deserialisation in RsGenExchange, conversion
to service structures in p3GxsChannels, then the model update in the GUI.

Add a small header-only helper (gxs/rsgxsprofiler.h) and instrument those
layers so each reports its own breakdown on one line. Profiling stays off
unless the RS_GXS_PROFILE environment variable is set; its value is a
reporting threshold in milliseconds so only the operations worth looking at
show up (RS_GXS_PROFILE=0 reports everything).

The reported counters are the ones that matter for the known bottlenecks:
number of SQL queries issued and blob volume read in retrieveNxsMsgs, number
of metas walked in retrieveGxsMsgMetaData, mGenMtx wait and deserialisation
time in getMsgData, and the token wait in getChannelAllContent.

No behaviour change: when profiling is disabled the added work is a couple of
steady_clock reads per call and one comparison against a cached threshold.

== RetroShare library

RetroShare is a decentralized, private, secure, cross-platform, communication
software.

RetroShare functionalities (file sharing, chat, messages, forums, channels...)
are implemented under the hood by libretroshare which offers a documented C++ and
JSON API.

While RetroShare is an application on its own, libretroshare is meant to be
used as part of other programs, some of them are
https://retroshare.cc[RetroShare-gui],
https://retroshare.cc[RetroShare-service],
https://gitlab.com/elRepo.io/elRepo.io-android[elRepo.io]
(let us know if there are more).


=== Continuous integration

=== Developer Documentation

All public API methods are documented with Doxygen comments, so the most updated
way to read documentation is reading those comments in `src/retroshare/`.

To use libretroshare as part of your Android application we suggest to add our
maven repository, and then specify the variant and version that fits your needs
as dependency. RetroShare is then exposed as an Android Service as you can see
at https://gitlab.com/RetroShare/libretroshare/-/blob/master/src/rs_android/org/retroshare/service/RetroShareServiceAndroid.java?ref_type=heads[RetroShareServiceAndroid.java] start it and then interact with it
via RetroShare JSON API.

.Example of adding libretroshare as dependency in Gradle
--------------------------------------------------------------------------------
repositories {
	maven {
		url "https://gitlab.com/api/v4/projects/32730908/packages/maven"
	}
}

dependencies {
	// Look at https://gitlab.com/RetroShare/libretroshare/-/packages for
	// available options.

	//                                            Build variant goes here ⬇
	//                                                          Version goes here ⬇
