smokey/posix-mutex: Fix test case by destroying barriers correctly
At least on x86-64-compat, the missing destruction of the smokey
barriers, specifically their embedded mutexes, cause crashes of the
test. The reason is likely a mismatch between the kernel's and
userland's view on which object is still active, combined with the fact
that userland kept them on the volatile stack.

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/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.

cobalt/arm64: fix build for mismatched printf type (%lx,u64) on arm64.
pc and orig_r0 are u64 on arm64 and 'unsigned long' or arm and other
platforms. printf referencing these are using %lx. On arm64, long and long long
(and u64) are 64 bits. Rather than changing printf format, chnage arm64 macros
to cast to unsigned long.

Depending on the uClibc-specific, internal __STDIO_PUTC_MACRO for
detecting macro-ized *putc* services is non-portable, unlikely to work

Use a more robust approach by directly detecting the definition of
macros for those services. This change also enables non-wrapped access
to such calls, which was not available until then (__STD() calls were
routed to the wrapper regardless).

boilerplate/setup: postpone detection of late setup calls
Since #d6d8047, setup descriptors may be registered after the base
inits have been performed, if DSO bootstrap modules were activated.
Postpone the detection of late setup calls after the main bootstrap
module has run instead.
This fixes an issue with --enable-assert in presence of DSO bootstrap
code.

boilerplate/setup: allow DSO bootstrap modules to coexist with main one
Gluing a PIC bootstrap module to a DSO is a common way to start the
Xenomai services before constructors of static C++ objects
instantiated by the DSO and which depend on such services, are
invoked.
With such module present in the DSO, a Cobalt-based application
process would attach itself to the Cobalt core via the bootstrapping
sequence, enabling the real-time services for the whole process,
including the static C++ constructors which may be invoked when
attaching the shared object.
e.g. in libfoo.so:
class FOO {
protected:
sem_t sem;
public:
static FOO bar;
};
...
FOO FOO::bar;
FOO::FOO()
{
// Initialize a Cobalt semaphore
sem_init(&sem, 0, 0);
}
However, adding a bootstrap module to a DSO currently prevents from
merging a second bootstrap module aimed at kickstarting the main
program's setup code and early inits, due to conflicting symbols and
the restriction on invoking xenomai_init() only once for any given
process.
The changes introduce a DSO-specific initialization service
(xenomai_init_dso()), which may be called from the context of the
dynamic linker attaching a shared object to the current
executable. The DSO-specific bootstrap module - if present - will call
xenomai_init_dso(), there is no restriction on the number of DSOs
calling this service.
The non-DSO bootstrap module invokes xenomai_init() as previously, for
kickstarting the main program's early inits.

lib/cobalt: modechk: switch to shared object, drop cxa wrappers
Dynamically linked code from shared libraries which may reference mode
checking wrappers cannot depend on symbols which are only visible from
the static link phase, such as those defined by the libmodechk.a
library. Otherwise, unresolved references to symbols from libmodechk.a
may exist in shared objects such as libcopperplate.so.
Unfortunately, we can't interpose on the cxa* API from a dynamic
library, since the latter would create references to "real"
__cxa_acquire/release/abort() routines, which are not available from
plain C builds since only libstdc++ defines them.
Providing placeholders for the cxa* API calls in a dynamic object is
not an option either, since that would create a dependency on the link
order between libmodechk and libstdc++ for pulling the actual symbols
instead of the dummy ones, which is not acceptable. Besides, relying
on LD_DYNAMIC_WEAK is fragile, unpractical, and won't work in secured
execution mode.
To work around this chicken-and-egg issue, make libmodechk a shared
object, and drop mode checking for the cxa* API for now. We'll revisit
the issue of enabling back the cxa* API later.

lib/cobalt: wrap CXXABI One-time Constructor functions
The implementation of these functions uses locks and has the potential
to trigger a SIGXCPU when contended. Wrap them with assert_nrt so they
reliably cause a switch when used in the rt context.

lib/cobalt: move mode checking wrappers to static archive
The mode checking wrappers must reside in a static archive, so that
the linker will pull them on demand, dropping the requirement for
providing potentially conflicting placeholders for wrapped symbols
which may not be present in both C and C++ support libraries
(e.g. __cxa_guard_acquire/release/abort from the one-time C++
constructor API).

drivers/ipc: reduce stack footprint of I/O vectors
Resort to dynamic allocation of the I/O vector when more than 16
entries are needed, otherwise stick to a stack-based fast vector as
previously.
As a by-product of this change, we can now align on the regular
UIO_MAXIOV limit for all RTIPC protocols.
