r254224:
  Update the wrapper script to 'release.sh', as used by the
  FreeBSD Release Engineering Team as of 9.2-RELEASE.

  Document that a cross-build release is possible by setting
  the TARGET and TARGET_ARCH variables.

  Include an example of using release.sh with and without the
  optional configuration file.

  Document the supported release.sh configuration file variables.

  Update the 'cdrom' target output file to disc1.iso.

  Update the 'memstick' target output file to memstick.img.

  Add attributions for the last major updates to this manual page.

  Fix some mdoc(7) style nits.

r254294:
  Remove the defaults for TARGET/TARGET_ARCH.

  Note that WORLD_FLAGS and KERNEL_FLAGS set the number of
  make(1) jobs only on SMP-capable systems.

r254328:
  Remove the {SRC,DOC,PORT}REVISION variables from release(7), and
  update the default {SRC,DOC,PORT}BRANCH defaults.

r258307:
  Add a script and configuration files to fetch pre-built packages
  from pkg.FreeBSD.org for inclusion on release medium (dvd1.iso).

  The script sources ${.CURDIR}/${TARGET}/pkg-stage.conf, which sets
  several environment variables, such as the pkg(8) ABI, PACKAGESITE,
  PKG_DBDIR, and PKG_CACHEDIR.  PKG_CACHEDIR is set to the directory
  on the release medium used by bsdconfig(8) (/packages/${ABI}).  ABI
  is determined by output of 'make -C /usr/src/release -V REVISION'.
  See pkg.conf(5) for descripton on other variables set here.

  The list of packages to include are set within the configuration
  file.

  The script and configuration files are intended to be run by the
  'make dvd' target within the release directory, and assume the
  release is built within a chroot environment (such as by using
  release.sh).

r258309:
  Set the PKG_CACHEDIR directory to 'dvd/' instead of 'release/'
  in preparation of adding a 'dvd1.iso' target.

r258310:
  Add the 'dvd1.iso' target.  This mimics the 'release.iso' target,
  with the additional step of fetching packages for inclusion on the
  dvd image.

  The 'pkg-stage' target is used to run 'scripts/pkg-stage.sh' if
  the '${TARGET}/pkg-stage.conf' configuration file exists (currently
  only amd64 and i386).

  Allow dvd1.iso to be skipped if NODVD=1.

r258314:
  Fix how ABI is evaluated so it matches more than a dot-zero
  case.

r258317:
  Document the 'dvdrom' target.

r258319:
  Remove WITHOUT_PROFILE=1 for the dvd1.iso medium.

r258320:
  Simplify PKG_ABI for pkg-stage.sh.

r258669:
  Document the dvdrom target and NODVD variable.

r258786:
  Move OPTIONS_UNSET outside of the PBUILD_FLAGS variable, otherwise
  the textproc/docproj port build fails.

r258853:
  Turn off the dvdrom target by default.  dvd1.iso is now built by
  specifying 'WITH_DVD=1' during 'make release'.

r258949:
  Ensure WITH_DVD is not empty to prevent 'WITH_DVD= ' from evaluating
  to true.

r259079:
  Add WITH_DVD to RELEASE_RMAKEFLAGS, otherwise it is not actually
  passed to 'make release'.

r259246:
  Prevent release build errors found during snapshot builds where if
  NOPORTS=1, pkg-stage.sh cannot build the ports-mgmt/pkg port if
  WITH_DVD=1.

MFC r255194 and prerequisites r229494,229496:

  Introduce internal macros for __U/INT64_C to define the U/INT64_MAX/MIN
  values properly. The previous definition only worked if __STDC_LIMIT_MACROS
  and __STDC_CONSTANT_MACROS were defined at the same time.

  Newer versions of gcc define __INT64_C and __UINT64_C, so avoid
  redefining them if gcc provides them.

Applying r255194 fixes stable/9 host to allow source upgrading to the newer
versions with usr.bin/dtc included in bootstrap tools.

Approved by:	imp (MFC to stable/9)
Improve compatibility with earlier parts of the 9 branch by defaulting
to MK_CLANG_IS_CC is no when it isn't otherwise defined. Also,
bsd.compiler.mk wasn't present in 9.0, so don't require it. With these
changes, you can compile a tip of 9.x kernel and modules old-school on
a 9.0 system.

MFC r259108:
When comparing device IDs, make sure that they have the same type
(like NAA assigned) and identify the same entity (like device or port).
Otherwise there can be false positives since at least some models of
Seagate disks use same IDs for the whole device and one of its ports.
Direct Commit of mountroot> prompt fix r259748 (since there's no sane
branching relationship between that branch and this one and since the
more general fix in head may be too risky for a stbale branch this
mature):

 Fix mountroot> prompt eating most of the characters by not enabling
 RXRDY interrupts in the attach routine. Instead, defer this until the
 first interrupt we see after the device is opened. Given the console
 use case, we're guaranteed to get a TXRDY interrupt before any reads
 are posted due to boot messages, which makes this work.

 The real fix is to use cngrab/cnungrab function pointers to disable
 RXRDY interrupts while grabbed. However, that touches the MI uart
 code, so was disallowed for 10.0 due to the lateness of the hour this
 fix was proposed. It works for mountroot, the most common atmel kernel
 prompt use cases, but wouldn't work for GELI since it prompts later in
 the boot process.
MFC r256060,r256650: kldxref: Do not depend on the directory order.

Sort the filenames to get a consistent result between machines of the same
architecture.

Also, sort FTS_D entries after other entries so kldxref -R works properly in
the uncommon case that a directory contains both subdirectories and modules.
Previously, this may have happened to work, depending on the order of files
in the directory.
