cobalt/heap: rebase on HEAPMEM algorithm
Address the issue mentioned in [1] regarding the core (xnheap)
allocator, using a variant of the McKusick scheme significantly
improving the performance figures.
As a by-product of this overhaul, the core allocator can now manage
heaps up to (4GB - PAGE_SIZE).
The performance report log obtained by testing on imx6qp
is as follows:

boilerplate: add heapmem allocator
This is the umpteenth incarnation of the McKusick allocator, aimed at
replacing other allocators which have serious issues:
- TLSF is fast but not that good when it comes to memory overhead with
small sizes (i.e. < 512 bytes) on 64bit.
- heapobj-pshared has decent overhead figures but may be insanely slow
at deallocating blocks from large, hot heaps.
- the Cobalt core allocator is even worse than heapobj-pshared in
deallocating blocks, although the system heap should be generally
small enough not to trigger the most pathological cases in practice,
hopefully. Nevertheless, the performances are unacceptable.
The original McKusick algorithm implements a quick fit allocation
scheme, based on bucket management of ^2-sized chunks, which
automatically switches to a page-based allocation method for blocks
larger than twice the base page size.
This variant maintains the free page list in AVL trees for fast
lookups of multi-page memory ranges, and pages holding bucketed memory
have a quick allocation bitmap to manage their blocks internally.
The current implementation can replace TLSF for delivering
process-local memory with similar performances but lesser overhead
with small sizes. Most importantly, a kernel variant of HEAPMEM should
replace the Cobalt core allocator. Likewise, heapobj-pshared which is
beyond repair should be replaced with a process-shareable variant as
well, assuming the average size and allocation patterns of real-time
objects are similar in all contexts.

net: create sysfs nodes for net devices
Each rtnet device registered with the stack is represented by a node
into /sys/devices/virtual/rtnet/.
Setting the address of the real device probed by the kernel into the
rtnet_device.sysbind field before calling rt_register_rtnetdev(),
causes the "adapter" symlink to be installed in the newly created
attribute directory, pointing at that device.
e.g.
static int probe_handler(struct pci_dev *pdev, const struct pci_device_id
*ent)
{
...
rtdev->sysbind = &pdev->dev;
...
ret = rt_register_rtnetdev(rtdev);

Xenomai task switches in kernelshark (so far via out-of-tree patches,
upstream is planning for the necessary plugin concept).
Moreover, reporting the current priority on context switch helps
debugging unexpected or delayed context switches

cobalt/tracing: Convert cobalt_print_sched_params into proper function
The code of cobalt_print_sched_params is carried into the format string
in tracefs, and trace-cmd tries to make any sense out of it. While it
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()).

At least on x86-64-compat, the missing destruction of the smokey

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.

cobalt/arm64: drop obsolete config knob

cobalt/sched: detect preemptible switch support in pipeline
CONFIG_XENO_ARCH_UNLOCKED_SWITCH is merely an alias for
CONFIG_IPIPE_WANT_PREEMPTIBLE_SWITCH, which is only meaningful to the
ARM architecture, now that PowerPC dropped such support.
Use the pipeline symbol directly to make the dependency explicit.

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.

pc and orig_r0 are u64 on arm64 and 'unsigned long' or arm and other
