The uart virtual address changes as soon as we apply the kernel memory
map. gUART is used only after that, from serial_init() onwards. So it
should use the virtual address, and not the physical address it was
previously created with while parsing the FDT.

least one standalone function or static method uses CALLED, the macro

In BeOS, the tab label was synchronized with the view name. This means
BTab::SetLabel would change the view name. This behavior is unexpected,
and also annoying, for example it prevents using localized tab labels
but fixed view names for scripting.

Previously we ran DHCP negotiation on the looper thread. This meant
that we just blocked it for long periods of time, which stopped
configuration settings changes from working properly, and causing
the Network preferences panel to hang when net_server failed to
respond to its messages.
Now, we spawn a separate thread to do the real work on, and unlock
the looper around the recvfrom() with long timeouts. There's now a
kMsgAutoConfigureFailed that is sent when auto-configuration fails,
so that the AutoconfigLooper can fallback as before. Additionally,
the main NetServer class quits loopers for devices on any configuration
change, rather than deferring it unecessarily (and possibly wrongly, in
some cases.)
Fixes#18037. Probably fixes#17300 and may help with others.
* It's not really possible to distinguish between a first startup
and a restart inside app_server itself. Due to the new BServer
setup, the same port will still be used, too. So, change the
messages sent to just "AppServerStarted".
* Since the message is sent out much later than the port is created,
by the time applications see it, the app_server may have already
been started a while and applications may have connected to it.
So, check if we really need to reconnect in BApplication before
actually trying to do that.
* BWindow now starts with updates disabled, so they must be
enabled after reconnecting.
After this commit, basic app_server restart functionality works again;
it's restarted automatically by launch_daemon after dying or being killed
and applications automatically reconnect. However, some problems still
linger (e.g. Terminal doesn't always recreate its windows, colors
on the Desktop look wrong, missing desktop background image, etc.)
They're not needed anymore. The VMTranslationMap method was confusingly
named anyway, as the other Debug* methods are for use in KDL, while
this one required the regular locks and flush mechanisms.

These instructions are only available on more recent CPUs (MWAITX
on AMD since around 2015 or so, TPAUSE on Intel since around 2020.)
They allow idly waiting on the TSC even when interrupts are
disabled.
Most hypervisors do not have these available (KVM does provide
them, though not on all configurations), but on bare metal this
should make a nice difference to KDL power consumption: I tested
with a Ryzen 3700X, according to my UPS (so including monitor
and peripherals) the system used ~106 W at idle, 160 W in KDL
before this patch, and 125 W in KDL after it.

The idea is to add a facility that will use less CPU than
the loops we currently use. The default implementation just
calls spin(), which is rdtsc+pause. This already may save
some power compared to what we previously did, which was to
re-check serial ports, PS/2, etc. every single loop in
the debugger, broken up only by "pause".

"git status" in buildtools, cold disk cache in a 4-core VM, seems about
the same, maybe slightly slower (~0.5s seemed typical, out of 20-21s),
while with a hot disk cache it's much faster: ~9.8s -> ~2.4s. Compile

- CR2 register (fault address)

- Hardware error code
The hardware error code, interrupt number and fault address are not
modifiable by the signal handlers. The other registers can be modified.
This is used for example in dosemu to intercept errors from JIT generated
code and resume execution. Wine can also make use of it.
In order to not change the size of struct mcontext, these are inserted
in a region of the FXSAVE structure that is available for the OS to

The RTLD_GROUP flag to dlopen comes from Solaris. It makes the symbol
resolution for dlopen not use the global symbols from the current team
(anything that's already loaded). The loaded object must be explicitly
linked against any symbol it needs to use (or it can use dlsym to search
symbols in the global scope explicitly).
This is also how symbol resolution worked in BeOS, meaning we already
have the code to do this, and just need to enable it.
This can be used in dosemu, where DOS-like executable are linked against
their own C library and should not use symbols from libroot.
