Improve tprof(4)

- Multiple events can now be handled simultaneously.
- Counters should be configured with TPROF_IOC_CONFIGURE_EVENT in advance,
  instead of being configured at TPROF_IOC_START.
- The configured counters can be started and stopped repeatedly by
  PROF_IOC_START/TPROF_IOC_STOP.
- The value of the performance counter can be obtained at any timing as a 64bit
  value with TPROF_IOC_GETCOUNTS.
- Backend common parts are handled in tprof.c as much as possible, and functions
  on the tprof_backend side have been reimplemented to be more primitive.
- The reset value of counter overflows for profiling can now be adjusted.
  It is calculated by default from the CPU clock (speed of cycle counter) and
  TPROF_HZ, but for some events the value may be too large to be sufficient for
  profiling. The event counter can be specified as a ratio to the default or as
  an absolute value when configuring the event counter.
- Due to overall changes, API and ABI have been changed. TPROF_VERSION and
  TPROF_BACKEND_VERSION were updated.

PMCR.E should not be disabled from tprof.

PMCR.E controls not only performance event counters but also the cycle
counter operation, and the cycle counter may be used for cpu_counter.
Similarly, the 31st bit in PMINTENCLR and PMCNTENCLR controls the cycle
counter, not performance event counters, and should not be modified.

Add support for Privileged Access Never (ARMv8.1-PAN).

PAN provides the same functionality as SMAP on x86: it forbids kernel
access to userland pages when PSTATE.PAN=1, and allows such accesses when
PSTATE.PAN=0.

We clear SCTLR_SPAN, to guarantee that PAN=1 each time the kernel is
entered. We catch PAN faults and panic right away without further
processing. In copyin, copyout, etc, we temporarily authorize access to
userland pages.

PAN is a very useful exploit mitigation. Reviewed by ryo@, thanks. Tested
on Qemu. Enabled by default.

- On some systems with a different cache line size (and DIC,IDC) per CPU, trap "mrs Xt,ctr_el0" instruction
  to return the minimum cache line size of the system to userland.
- add CLIDR_EL1 and CTR_EL0 to struct aarch64_sysctl_cpu_id.

On most systems, cache line size is the same for all CPUs, so this mechanism won't be required.
Rather, this is primarily for errata support, which will be committed later.

Add support for Pointer Authentication (PAC).

We use the "pac-ret" option, to sign the return instruction pointer on
function entry, and authenticate it on function exit. This acts as a
mitigation against ROP.

The authentication uses a per-lwp (secret) I-A key stored in the 128bit
APIAKey register and part of the lwp context. During lwp creation, the
kernel generates a random key, and during context switches, it installs
the key of the target lwp on the CPU.

Userland cannot read the APIAKey register directly. However, it can sign
its pointers with it, because the register is architecturally shared
between userland and the kernel. Although part of the CPU design, it is
a bit of an undesired behavior, because it allows to forge valid kernel
pointers from userland. To avoid that, we don't share the key with
userland, and rather switch it in EL0<->EL1 transitions. This means that
when userland executes, a different key is loaded in APIAKey than the one
the kernel uses. For now the userland key is a fixed 128bit zero value.

The DDB stack unwinder is changed to strip the authentication code from
the pointers in lr.

Two problems are known:

 * Currently the idlelwps' keys are not really secret. This is because
   the RNG is not yet available when we spawn these lwps. Not overly
   important, but would be nice to fix with UEFI RNG.
 * The key switching in EL0<->EL1 transitions is not the most optimized
   code on the planet. Instead of checking aarch64_pac_enabled, it would
   be better to hot-patch the code at boot time, but there currently is
   no hot-patch support on aarch64.

Tested on Qemu.

rewrite the CPU identification on arm64:

- publish per-cpu data
- publish a whole bunch of info in struct aarch64_sysctl_cpu_id
  instead of various individual nodes (there are 16 total.)
- add MIDR extractor bits
- define ARMv8.2-A id_aa64mmfr2_el1 and id_aa64zfr0_el1 regs,
  but avoid using them until we make sure they exist.  (these
  members are added to aarch64_sysctl_cpu_id to avoid future
  compat issues.)

the arm32 and aarch32 version of these need to be adjusted as
well (and aarch32 data published at all.)  still trying to
work out how to make the same userland binary running on a
real arm32 or an aarch32 system can work sanely here.

ok ryo@.

When hardware subnormal support is available, disable flush-to-zero.

Similarly, when hardware NaN propagation is available, disable
default-NaN substitution.

This enables IEEE 754 semantics on any hardware that supports it by
default.  Programs that want flush-to-zero or default-NaN substitution
can enable them explicitly.

Workaround A-008585 errata in GTMR.

Register reads and writes may provide unstable results if the counter
hardware is active at the same time. This results in non-monotonic
counters seen by both the gtmr interrupt and time counter.

The loops are currently applied unconditionally, restricting them to
appropiate FDT markers can be applied later.
