This is a better pattern to follow when creating the bootloaders and doing
the relevant space checks to make sure that the sizes aren't exceeded (and
thus, copy-pasting is a bit less error prone).

bde enabled -fno-guess-branch-probability in 2003, well before our
current compiler was imported. At the time it produced weirdly orded
code. It no longer does that. It also saves 0-4 bytes depending on
other options.
kan disabled unit-at-a-time in 2004 because it badly mangled boot2 so
it wouldn't work. That too was before the 4.2.1 compiler, where it no
longer does that. This saves 44 bytes.
I had planned to document why they were needed, but when I discovered
their antiquity, I removed them and boot2 still works and is
smaller. In qemu, the old and new boot2's behaved identically.
These are gcc specific hacks, and won't affect clang-built boot2
at all.
- kvm_close: add a testcase to verify support for errno = EINVAL / -1
(see D10065) when kd == NULL is provided to the libcall.
- kvm_geterr:
-- Add a negative testcase for kd == NULL returning "" (see D10022).
-- Add two positive testcases:
--- test the error case using kvm_write on a O_RDONLY descriptor.
--- test the "no error" case using kvm_read(3) and kvm_nlist(3) as
helper routines and by injecting a bogus error message via
_kvm_err (an internal API) _kvm_err was used as there isn't a
formalized way to clear the error output, and because
kvm_nlist always returns ENOENT with the NULL terminator today.
- kvm_open, kvm_open2:
-- Add some basic negative tests for kvm_open(3) and kvm_open2(3).
Testing positive cases with a specific
`corefile`/`execfile`/`resolver` requires more work and would require
user intervention today in order to reliably test this out.

tcp_output.c was using a route on the stack for IPv6, which does not
allow route caching or LLE/ndp caching. Switch to using the route
(v6 flavor) in the in_pcb, which was already present, which caches

clang is now inserting .file directives with the entire path in
them. This is fine, except that our sed peephole optimizer removes
them if ${SRCTOP} or ${OBJTOP} contains 'align' or 'nop', leading to
build failures. The sed peephole optimizer removes useful things for
boot2 when used with clang, so restrict its use to gcc. Also, gcc no
longer generates nops to pad things, so there's no point in removing
it. Specialize the optimization to just removing the .align 4 lines to
preclude inadvertant path matching.

- Don't execute any of g_mirror_shutdown_post_sync() when panicking. We
cannot safely idle the mirror or stop synchronization in that state, and
the current attempts to do so complicate debugging of gmirror itself.
- Check for a non-NULL panicstr instead of using SCHEDULER_STOPPED(). The
latter was added for use in the locking primitives.

GNU libtool checks the output from invoking the linker with --version
and --help, in order to determine the linker "flavour" and the command-
ine arguments to use for various link operations (e.g. generating shared
libraries). To detect GNU ld it looks for the strings "GNU" and
"supported targets:.*elf". Since LLD is compatible with GNU ld we
include those same strings to fool libtool.
Quoting from a comment in the change:
This is somewhat ugly hack, but in reality, we had no choice other
than doing this. Considering the very long release cycle of Libtool,
it is not easy to improve it to recognize LLD as a GNU compatible
linker in a timely manner. Even if we can make it, there are still a
lot of "configure" scripts out there that are generated by old
version of Libtool. We cannot convince every software developer to
migrate to the latest version and re-generate scripts. So we have
this hack.
