archive_version: Returns a text string, e.g., "libarchive 1.00.000"
archive_api_version: Returns the SHLIB major version
archive_api_feature: Returns a feature number useful for answering
questions such as "Is this recent enough to do XXX?"
The last two also have macros defined in archive.h, so you can compare
the compile-time and run-time environments. (In particular, you can
compare ARCHIVE_API_VERSION to archive_api_version() to detect library
version mismatches.)
With these in hand, it will soon be time to turn on the
shared-library version of libarchive... stay tuned.
Properly wait for not busy and introduce a timeout for devices not
setting busy (as they should).
Leave a printf in there that states how long the wait was, as I'd like
to get an idea of the variations here. The time needed seems also to be
affected by whether a medium is present or not.
FOREACH_SAFE. Remove bad cast of retp and instead use an additional
arg to pass back the number of valid outputs. Use the package convenience
functions for parsing packages.
Thanks to: David O'Brien for pointing this out.
Also, add in a few additional portability tweaks and make a few
more things conditional on features (HAVE_XXXX macros) rather
than platform.
In particular, this means we can now correctly read gtar archives that
contain timestamps prior to the start of the Epoch.
Also, make the code in this area more portable. ANSI C99 headers are
not yet ubiquitous (for example, FreeBSD 4 still lacks them), so be
prepared for systems that don't have the INT64_MAX, INT64_MIN, and
UINT64_MAX macros. This version still requires int64_t and uint64_t be
defined (which can be done in archive_platform.h if necessary), but
doesn't require them to be exactly 64 bits.
o Separate out local (ports) scripts that use rc.d, and the old style
startup/shutdown scripts and execute them separately. On startup the
rc.d style scripts are executed first and then the old-style scripts.
On shutdown, exactly the reverse happens.
o The rc.d ports scripts should now behave more like base system scripts.
Scripts ending in .sh will be sourced into the current shell, while the
rest will be executed in a subshell. Previously, all ports scripts,
regardless of the .sh suffix, were executed in a subshell.
o The parent script, /etc/rc.d/localpkg, passes its command line arguments
straight to the rc.d ports scripts. This means they should now honor
faststop and faststart commands as well. Old style scripts, should not see
any differences. They will still get either a start or stop command.
o The initial phrase shown during shutdown has been changed to use
"local packages" instead of "daemon processes" to be more inline with the
phrase used during local package startup. The phrases are also used only for
old-style ports script startup/shutdown, whereas previously they were being
used for both rc.d and old-style scripts. This should make startup/shutdown
output a bit less ugly.

Has Reservations: eik
(in particular, bge(4) hasn't supported rxcsum since if_bge.c#1.5)
Clean up some aspects of capabilities usage, i.e. stop using
if_hwassist to see whether we are doing offload now because if_hwassist
is for TCP/IP layer and it is subordinate to if_capenable.
Thanks to: Aled Morris for donating a nice bge(4) NIC to me

vmspace to the new vmspace in vmspace_exec() is mostly wasted effort. With
one exception, vm_swrss, the copied fields are immediately overwritten.
Instead, initialize these fields to zero in vmspace_alloc(), eliminating a
bcopy() from vmspace_exec() and a bzero() from vmspace_fork().
can't yet be referenced by other threads.
In microbenchmarks, this appears to reduce the cost of
pipe();close();close() on UP by 10%, and SMP by 7%. The vast majority
of the cost of allocating a pipe remains VM magic.

calls further down the stack. If we find the cksum to be okay we pretend
that the hardware did all the work and hence keep the upper layers from
checking again.

addend of 0. This isn't correct, and was quite easy to break by
referring to the address of an element within a structure.
However, fixing this exposed the fact that symbol lookups for
local variables were returning the base of the section they
were contained in. This case is detected by comparing the return
value from elf_lookup() to the relocbase+addend value: if it is
lesser, but greater than relocbase, then relocbase+addend is
taken to be the authoritative value.

happens because the sio device was never opened and com->tp is
therefore NULL. ttygone can't swallow a NULL, so guard against that
possibility. Other places in this function make similar checks, so I
believe this is correct.
