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".

- CR2 register (fault address)

The hardware error code, interrupt number and fault address are not

This is used for example in dosemu to intercept errors from JIT generated
code and resume execution. Wine can also make use of it.

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.

To allow consumers to cause the "don't fragment" bit to be set in
all IPv4 packet headers.
There is no standard way of doing this, and different OSes expose
this option in different ways. Linux has "IP_MTU_DISCOVER", but it
takes an enum, not a boolean. NetBSD and OpenBSD appear to have
no socket option, instead they have "IP_MTUDISC", an option for
the "ip_output()" kernel-level network stack method.
"IP_DONTFRAG" sockopt originates on FreeBSD, and it seems macOS now
also supports it in version 11+. Windows has "IP_DONTFRAGMENT",
which, at a glance, appears to do the same thing. So this looks
like the one that makes the most sense to adopt.
This doesn't add any code to process MTU changes yet, though.
