   Be precise in checking for errors. pclose(3) returns -1 and fclose(3)
   EOF in case of errors, not any negative number.

   fix NULL deference (bzero) on error path added in last commit;
   spotted by Reynir Björnsson

   ok deraadt@ markus@ tb@

   If we don't receive a reply packet the res_send subquery will already have
   set subq_h_errno and ar_count. Remove the ar_datalen == -1 check, so we
   set ar_h_errno and don't have to (wrongly) guess that
   ar_h_errno = HOST_NOT_FOUND.

   This makes sure that if no nameserver responds the h_errno value is set to
   TRY_AGAIN instead of HOST_NOT_FOUND.

   Allow filters to log information through stderr. This simplifies and
   unifies the way filters need to get their logging to the right location.

   Log-messages are read line by line and are logged at LOG_ERR level via
   the lookup process.

   Remove unneeded unlink of xauthfile on error path.  From Erik Sjölund via

   The POSIX-compatible way of checking for {v,}{f,s,sn,d}printf(3)
   failure is with < 0, not the more specific -1 from C

   Use timeout_add_msec(9)

   To initiate LED blinking, simply kick of the timer after the blinking
   rate's period rather than one tick to get red of the last hardclock(9)
   based timeout in this driver.  The now increased delay is compensated by
   also turning on the LED immediately.

   Fix a typo in window_pane_find_down (w not wp) and a missing PANE_STATUS_TOP.

   Pass keys that aren't 0-9 on to normal key processing when display-panes
   is active (restores previous behaviour).

   allow more video(4) ioctls for the video pledge (required by chromium)

   Add some key and map logging.

   This diff uses the existing filename as the new filename if none is
   specified while copying in dired mode.

   This diff makes blink-and-insert do as the man page says it should do.
   If you do 'M-x blink-and-insert', you are asked for a character. mg
   will then insert it at the current cursor position and then search
   backwards for a corresponding match.

   In LLVM 8 somebody had the glorious idea to enable the integrated assembler
   for OpenBSD sparc64. The problem is that the integrated assembler is not
   even able to compile the .S files in lib/csu or lib/libc so revert this
   and use gas again. Fixes build issues with clang on sparc64.

   Return EINVAL, not EBADF for fcntl(fd, F_GETLK) of a non-vnode.
   Matches the recent F_SETLK change, POSIX and the man page.

   Log window and pane resizes.

   Fix some comments (top/bottom not left/right).

   Add #define for the pane status line option position numbers.

   Add support for OCSP stapling

   Many thanks to Bruno Flueckiger who independently sent a very similar
   patch.  He also tested the one I'm committing that it works as
   expected.

   Create IF_WWAN_DEFAULT_PRIORITY which is lower than
   IF_WIRELESS_DEFAULT_PRIORITY and use it in umb(4) as default prio.

   reject DATA containing <CR> that's not part of <CRLF> line terminators
   as they are not allowed by RFC, have never been generated by a regular
   MUA/MTA and can cause issues with some filters if we let them through.

   ok jung@ on an earlier version of the diff, eric@ suggested the new diff

   The MPLS edge devices get the packets from the MPLS stack which never
   passed though pf_test(). So there is no need to try to call
   pf_pkt_addr_changed() instead just check that the PF statekey is NULL.

   add support for bypassing iommu translation

   managing the translation table entries (TTEs) on an iommu is not
   free, and is in fact extremely expensive on some platforms. the
   flip side of this is that forcing dma through TTEs does provide
   some safety and can help during the development of drivers. however,
   this has been less true in recent years than it used to be and is
   less of a concern now, especially considering the performance
   differences on some platforms.

   devices have to create dmamaps with BUS_DMA_64BIT to bypass the
   iommu because the memory window presented to hardware with direct
   access to memory is at an extremely high address. there's no 32bit
   bypass access to memory, it has to go through TTEs otherwise.

   on an m4000 there are several orders of magnitude performance
   difference between a driver with BUS_DMA_64BIT set and one without
   it.

   hilariously, sun used a pci bridge on a whole generation of machines
   that had broken support for dma addresses over 40 bits (or around
   there), so devices behind those pci bridges need to have their
   dmamap_creates intercepted and any potential BUS_DMA_64BIT flags
   cleared on the way to the iommu drivers. this affects at least v215,
   v245, and v445, and probably u25s and u45s. it probably explains

   POSIX.1-2008 TC3 is going to clarify how newlocale(3) uses oldloc.
   Explicitly state that our implementation now complies with the
   stricter requirements of TC3 because the newlocale(3) in old OpenBSD
   releases only complied with the weaker requirements of the old text
   of the standard.  The complaints from our users resulted in both
   our implementation and the standard being improved.

   Turn off the code which waits for AHCI_PREG_CMD_CR to be set by the
   HBA after ahci_default_port_start() sets AHCI_PREG_CMD_ST. The AHCI
   spec. rev. 1.3 only requires the inverse to be true, i. e. that a
   HBA clears AHCI_PREG_CMD_CR when AHCI_PREG_CMD_ST gets cleared by
   software/driver. In fact, some HBAs will not raise AHCI_PREG_CMD_CR
   as an immediate consequence of AHCI_PREG_CMD_ST being set. Actually
   neither the FreeBSD, Linux nor NetBSD counterpart of ahci(4) has an
   analogous check. Disabling that wait fixes "failed to start command
   DMA on port N, disabling" bails during attach.

   Add 'dired-revert' to the dired funmap, the 'g' command already works

   Initialize the peer id of peerself to PEER_ID_SELF before adding it to
   peer table. Fixes an endless loop of peer_down errors on shutdown.

   Remove irrfilter from bgpctl. The current code is not very useful.
   Trying to parse RPSL has shown to be impossible. For now tools like
   bgpq3 (in ports) can be used to generate AS and prefix sets based on

   Since the recent recursion fix in rtable_walk(), deleting an interface
   address could trigger the "rt->rt_ifidx == ifp->if_index" assertion.
   In rtflushclone() the ifp that is passed to rtdeletemsg() has been
   changed from the route interface to the ifa interface.  Restore the
   old behavior and get the route ifp.

   Use timeout_add_sec(9)

   Re-challenge timeouts are made up of single scalar factors which are
   multiplied with the time unit lcp.timeout to compute the timeout period.

   Simply reduce that unit of 1 * hz [ticks] to 1 [s] and use the appropiate
   API.

   switch-to-buffer (C-x b) doesn't cancel properly if C-g is pressed.
   It doesn't show 'Quit'. By returning ABORT, it behaves as expected
   when C-g is pressed (like all other functions that use the
