The main change was v1.57 by djm@:
Randomise the rekey interval a little. Previously, the chacha20
instance would be rekeyed every 1.6MB. This makes it happen at a
random point somewhere in the 1-2MB range.

Here, the provider is responsible for updating the trapframe to redirect
control flow and for computing the return address. Once software-saved
registers are restored, the emulation shifts the remaining context down
on the stack to make space for the return address, then copies the
address provided by the invop handler. dtrace_invop() is modified to
allocate temporary storage space on the stack for use by the provider to
return the return address.
This is to support a new provider for amd64 which can instrument
arbitrary instructions, not just function entry and exit instructions as
FBT does.

This is in preparation for including an etcupdate tree when performing a
-DNO_ROOT release image build. Although -DNO_ROOT can be passed via -M,
to be useful we need to mangle the resulting METALOG to mirror the
various cleanups to the tree that are done after the build (removing
generated files, empty files and empty directories), so etcupdate needs
its own flag.

This is in preparation for building an etcupdate tree on non-FreeBSD
when building release images. The -d option is documented as a
BSD-specific equivalent to the POSIX -depth primary. Whilst GNU find
sort of accepts it in an attempt to be compatible, it still doesn't
permit it coming before the paths, unlike BSD find, and prints a
deprecation warning either way. Thus, use the equivalent POSIX -depth to
ensure it works correctly and without warning everywhere.

This is in preparation for non-FreeBSD and -DNO_ROOT builds. On
non-FreeBSD there is no host etcupdate to use, and -DNO_ROOT will
require additional flags that may not be supported by the host's
etcupdate when building on FreeBSD. Moreover, there's no guarantee
anyway that the host's etcupdate is quite right for the current tree;
upgrading from source only requires that the host's is good enough for
-p which just manually copies master.passwd and group, the rest of the
upgrade is done post-installworld. For example, should a new set of
autogenerated files be added that etcupdate is taught about, the host
won't know about them and so the bootstrapped current tree will
incorrectly contain them, leading to spurious diffs on the installed
system.

As in vm_fault_cow(), it's possible, albeit rare, for multiple vm_maps
to share a shadow object. When copying a page from a backing object
into the shadow, all mappings of the source page must therefore be
removed. Otherwise, future operations on the object tree may detect
that the source page is fully shadowed and thus can be freed.

Resulting sbuf_len() from proc_getargv() might return 0 if user mangled
ps_strings enough. Also, sbuf_len() API contract is to return -1 if the
buffer overflowed. The later should not occur because get_ps_strings()
checks for catenated length, but check for this subtle detail explicitly
as well to be more resilent.
The end result is that p_comm is used in this situations.

Recover application ability to supply fabricated PID
embedded into ident that was lost when libc switched
to generation of RFC 5424 log messages, for example:
logger -t "ident[$$]" -p user.notice "test"
It is essential for long running scripts.
Also, this change unbreaks matching resulted entries
by ident in syslog.conf:
!ident
*.* /var/log/ident.log
Without the fix, the log (and matching) was broken:
Aug 1 07:36:58 hostname ident[123][86483]: test
Now it works as expected and worked before breakage:
Aug 1 07:39:40 hostname ident[123]: test

Fix two bugs in __cxa_end_cleanup()
Per the EHABI32 specification, __cxa_end_cleanup must take care to
preserve registers before calling _Unwind_Resume(). So, libcxxrt uses
an assembly stub which preserves caller-saved registers around the call
to __cxa_get_cleanup(). But:
- it failed to restore them properly,
- it did not preserve the link register.
Fix both of these problems. This is needed to fix exception unwinding
on FreeBSD with LLVM 14. Note that r4 is callee-saved but is pushed
onto the stack to preserve stack pointer alignment.
