cobalt/tracing: Primarily identify threads via pid
Except for the short phase between thread_init and shadow_map, a thread
is always identifiable via the pid of its Linux mate. Use this shorter
value, which also correlates with what ftrace records anyway, instead of
the pointer or the name. Report the full thread name only in prominent
cases: init, resume and switch.

cobalt/tracing: Convert cobalt_print_sched_params into proper function
The code of cobalt_print_sched_params is carried into the format string

can process simply statements, this code is too complex and will prevent
the parsing.
Convert it into a function. That still does not resolve the parsing
issue of trace-cmd, but that can be addressed by a custom plugin which
can then interpret this tracepoint. That wouldn't be possible with the
broken format string.

cobalt: Introduce xnftrace_printf
This allows to inject a user-defined string into the system's ftrace
without leaving RT mode (because of using a standard write on
/sys/kernel/debug/tracing/trace_marker).
As the signature of this function is different from the existing trace
syscall, create as dedicated one.
For simplicity reasons, the maximum string length that can be passed
down to the kernel is limited to 255 characters (+1 for termination).
We call directly into the internal __trace_puts to avoid both the
unneeded strlen call of the trace_puts wrapper and the false warning
that kernel code uses trace_printk.

cobalt/timer: fix, rework ptrace detection and timer forwarding
Ptracing may cause timer overruns, as the ptraced application cannot
go waiting for the current period in a timely manner when stopped on a
breakpoint or single-stepped. A mechanism was introduced a long time
ago for hiding those overruns from the application, while ptracing is
in effect.
The current implementation dealing with this case has two major flaws:
- it crashes the system when single-stepping (observed on ARM i.MX6q),
revealing a past regression which went unnoticed so far.
- it uses a big hammer to forward (most) timers without running their
respective timeout handler while ptracing, in order to hide this
timespan from the overrun accounting code. This introduces two
issues:
* the timer forwarding code sits in the tick announcement code,
which is a very hot path, despite ptracing an application is
definitely not a common operation.
* all timers are affected / blocked during ptracing, except those
which have been specifically marked (XNTIMER_NOBLCK) at creation,
which turns out to be impractical for the common case.
The new implementation only addresses what is at stake, i.e. hiding
overrun reports due to ptracing from applications. This can be done
simply by noting when a thread should disregard overruns after an exit
from the ptraced mode (XNHICCUP), then discard the pending overruns if
this flag is detected by the code reporting them
(xntimer_get_overrun()).

cobalt/syscalls: allow for handing over mode selection to syscall handlers
Specific system calls may benefit from dealing with the caller's
runtime mode by themselves, depending on internal information which
the generic syscall dispatcher does not have access to.
To this end, a new syscall mode called "handover" is
introduced. Syscalls bearing this mode bit are always entered from the
current calling domain. The syscall handler may return -ENOSYS to
trigger a switch to the converse domain until all domains have been
visited once, at which point the syscall fails with -ENOSYS
automatically.

lib/cobalt: use lazy schedparam propagation
Do not switch to secondary mode upon schedparam updates for
propagating changes to the regular kernel, if the caller runs in
primary mode when entering pthread_setschedparam*() or
sched_setscheduler(). In such a case, the update request to the
regular kernel is left pending until the target thread resumes
execution in relaxed mode, at which point it is committed.
CAUTION: This mechanism won't update the schedparams cached by the
glibc for the caller in user-space, but this is the deal: we don't
relax threads which issue pthread_setschedparam[_ex]() from primary
mode anymore, but then only the kernel side (Cobalt and the host
kernel) will be aware of the change, and glibc might cache obsolete
information.
If the caller already runs in relaxed mode on entry to these services,
the update request takes place immediately, via the regular (g)libc
calls.
In any case, the new scheduling parameters for the target thread are
immediately applied by Cobalt, regardless of the update path followed
for the regular kernel.

cobalt/thread: add schedparam lazy propagation
Provide a mechanism for carrying out a lazy propagation of schedparam
updates to the regular kernel, so that userland does not have to
switch to secondary mode for this.
When userland issues sc_cobalt_thread_setschedparam_ex for updating
the scheduling parameters of a Xenomai thread, a request for
propagating this change to the regular kernel is made pending. Such
request will be committed later, either when:
- the thread relaxes if it is running in primary mode when the update
request is received;
- next time the thread calls back into the Cobalt core as a result of
receiving a HOME action from a SIGSHADOW notification, which is sent
if such thread was relaxed at the time of the update request.
As a result, the target thread will have propagated the schedparams
update to the regular kernel as soon as it resumes (relaxed) execution
in user-space.

smokey/posix-mutex: Fix test case /wrt mutex object reuse
Mutex objects created on the stack must be properly destroyed after use.
Otherwise, succeeding tests that use the same stack layout will consider

cobalt/powerpc: drop support for unlocked context switch
This feature never actually brought any measurable gain on powerpc
platforms, compared to the complexity of its implementation in the
pipeline. It was primarily aimed at reducing latency for interrupt
handlers when costly cache and TLB flushes are required to switch
context, at the expense of increasing the scheduling latency. It
turned out to be counter-productive on common powerpc platforms, with
efficient MMUs.
This feature has been default off for a while now, and 4.1+ pipelines
won't provide support for it anymore. Time to drop support from
Xenomai too.

cobalt/arm64: restrict unlocked switch to SMP
Unlocked switching for Xenomai/ARM was specifically introduced for
improving the interrupt latency on low-end armv4/armv5 platforms with
VIVT caches.
The once massive overhead imposed on the MMU context switching code
for invalidating the cache is long gone with VIPT indexing, and
keeping IRQs off while switching the memory context on armv8 these
days is not an issue. Actually, the complexity of the code involved in
dealing with unlocked switching may overbalance the expected gain.
However, the mainline kernel implementation for ASID management in the
SMP case currently requires us to keep IRQs enabled when allocating a
new MM context over the Xenomai domain, just like it did for aarch32
during the 2.6.3x time frame until the IPI-based approach was
eventually dropped.
So, let's restrict unlocked switching to the SMP case, forcing it off
otherwise, in the hope we can drop it entirely in the future.
At this chance, CONFIG_IPIPE_WANT_PREEMPTIBLE_SWITCH moves to the
kernel area, where it actually belongs.
