The internal functions blocking threads
for implementing call_sync were not releasing
the event loop, leading to deafness of the
binder.
Include a tuto-4 that reproduce the issue
on a binder with the bug and that also shows
interesting usages of the binder.

Foreign threads, that are not started by jobs,
are allowed to use synchronous jobs_call/job_leave
(directly or indirectly).
This commit ensure that those foreign thread will
neither acquire the eventloop nor execute jobs.
Includes a tiny cleanup of remain usage.

This improves the arbitration of the single event
loop across threads.
Before introduction of using 'evenfd' there was
several event loop. At the current time, there
is only one. At the end, there will probably
remain only one.

The C++ compiler is too much strict. It doesn't accept
valid C because fields are in the wrong order or missing.
- afb_verb_t generated structure invert vcbdata and session
- missing provide_class, require_class, require_api in the
afb_binding_v3 generated struct
The signature of the declared function was wrong.
- wrong verb's callback signature void fun(afb_req) instead of
void fun(afb_req_t)
This add the declaration of the (pre)initialization and onevent functions.
- missing init function signation generation, or probably preinit and
onevent (not tested those ones)

The introduction of API v3 changed the API of
monitoring/tracing. This introduced a regression
of the monitoring: it wass not more possible to
filter api by name. This fix that issue.

For bindings v3, it is possible to have no
explicit default root API.
In that case, the binder creates a fake API
that references the binding itself. That api
isn't callable be it allows to emit messages,
to catch events and to call services (other
apis).
It must be kept to ensure that there is no
further error in the hypothetical case where
it is used.

The use of the generator given by the lib uuid
implies the use of the system call 'getrandom'
without the flag GRND_NONBLOCK. It has a weird
effect on boot because many binders require
the generation of uuid at the same time but
getrandom is subject to starving.
This introduced a tiny pseudo-random generation
of UUID that does not implies the use of 'getrandom'.

doesn't handle .html files I had to change it.

The binder traps faults by default to recover as much as
possible from unexpected errors.
Developers may need to remove that behaviour to get core file.
This introduces 2 ways to set or remove the trapping of faults:
- the environment variable AFB_TRAP_FAULTS
- the command line option --trap-faults
Both take a boolean value set using on of the following words:
1 yes true on -- enable trapping of faults (the default)
0 no false off -- disable trapping of faults

It may be difficult to retrieve the root directory from bindings
and from process spawn by option --exec.
In the same way, well identifying the workdir might interest
programs or bindings.
So, from now, the environment variables below are set:
- AFB_ROOTDIR: identify the rootdir as set by --rootdir
and in the context of AGL it will be the widget directory
- AFB_WORKDIR: identify the workdir as set by --workdir
To avoid any confusion, the function realpath is used to export
absolute path names.

When sd_event_prepare returns an error there is currently
no way to restore the event loop working.
It happens when a callback of an sd_event is faulty
(ex: SIGSEGV). In that case the monitoring of signals
(sig-monitor) interfer badly with systemd. But at the
the application firstly has error.
To avoid flooding the journal with messages, aborting
is the best solution.

The verb mutebug returns without answering
but increment the reference count of the request.
This has 2 weird effects:
- on the service, it creates a memory leak
- on the client, it creates a starve of answer
Both effects are intended to test further improvements
of the binder.

This change allows a binding to know its
installation path. This path is retrieved using
the api function 'afb_api_settings'.
The path is returned --if known-- as a string
