For increased compatibility with GNU units: support a -v option which
produces more verbose output when spitting out the answer.
GNU -v does additional work in the version, information, and check output which
we do not (yet?) replicate.
was stacked on top of network interfaces that set if_hw_tsomax,
tcp_output() would see the default value instead of the value
set by the network interface(s). This patch modifies lagg so that
it sets if_hw_tsomax to the minimum of the value(s) for the
underlying network interfaces.

sfxge: RXQ index (not label) comes from FW in flush done/failed events
Change the second argument name of the efx_rxq_flush_done_ev_t and
efx_rxq_flush_failed_ev_t prototypes to highlight that RXQ index (not label)
comes from FW in flush done and failed events.
sfxge: TXQ index (not label) comes from FW in flush done event
Change the second argument name of the efx_txq_flush_done_ev_t prototype to
highlight that TXQ index (not label) comes from FW in flush done event.
sfxge: use TXQ type as label to support more than 32 TXQs
There are 3 TXQs in event queue 0 and 1 TXQ (with TCP/UDP checksum offload)
in all other event queues.

sites and installing a hook at the kernel's trap handler. The fasttrap code
will emulate the overwritten instruction in some common cases, but otherwise
copies it out into some scratch space in the traced process' address space
and ensures that it's executed after returning from the trap.
In Solaris and illumos, this (per-thread) scratch space comes from some
reserved space in TLS, accessible via the fs segment register. This
approach is somewhat unappealing on FreeBSD since it would require some
modifications to rtld and jemalloc (for static TLS) to ensure that TLS is
executable, and would thus introduce dependencies on their implementation
details. I think it would also be impossible to safely trace static binaries
compiled without these modifications.
This change implements the functionality in a different way, by having
fasttrap map pages into the target process' address space on demand. Each
page is divided into 64-byte chunks for use by individual threads, and
fasttrap's process descriptor struct has been extended to keep track of
any scratch space allocated for the corresponding process.
With this change it's possible to trace all libc functions in a program,
e.g. with
pid$target:libc.so.*::entry {@[probefunc] = count();}
Previously this would generally cause the victim process to crash, as
tracing memcpy on amd64 requires the functionality described above.

If realpath() is called on pathnames like "/dev/null/." or "/dev/null/..",
it should fail with [ENOTDIR]. Pathnames like "/dev/null/" already failed as
they should.
Also, put the check for non-directories after lstatting the previous
component instead of when the empty component (consecutive or trailing
slashes) is detected, saving an lstat() call and some lines of code.

Leave them in place for the normal, non-posix enviornment since
they are quite useful there.
issues with vendors that needed 7.x support have been resolved. Many
vendors are still using 8.x build platforms, however, so bumping this
up to 9.0 will have to wait until that is resolved. Actual support for
building from 8.x still relies on those vendors fixing bugs that are
present as most developers have moved onto 9.x or newer platforms.

way. This allows a clang bootstrap to happen, even when WITHOUT_CLANG
is defined. This is a minimal version of a more extensive change which
can be MFC'd more easily. However, we have to also test to see if
we're building clang as not cc, since the bootstrap for that needs
these cross tools and it is easier to build them in just one place.
