r259550 (glebius):
Make nmdm(4) destroy devices when both sides of a pair are disconnected.
This makes it possible to kldunload nmdm.ko when there are no users of it.
r271350:
Fix issue with nmdm and leading zeros in device name.
The nmdm code enforces a number between the 'nmdm' and 'A|B' portions
of the device name. This is then used as a unit number, and sprintf'd
back into the tty name. If leading zeros were used in the name,
the created device name is different than the string used for the
clone-open (e.g. /dev/nmdm0001A will result in /dev/nmdm1A).
Since unit numbers are no longer required with the updated tty
code, there seems to be no reason to force the string to be a
number. The fix is to allow an arbitrary string between
'nmdm' and 'A|B', within the constraints of devfs names. This allows
all existing user of numeric strings to continue to work, and also
allows more meaningful names to be used, such as bhyve VM names.

- Use make_dev_p() in tty_makedevf() instead of make_dev_cred().
- Always pass MAKEDEV_CHECKNAME flag.
- Optionally pass MAKEDEV_REF flag.
- Provide macro for compatibility with old API.
This fixes races with simultaneous creation and desctruction of
ttys, and makes it possible to call tty_makedevf() from device
cloners.

fbd: Fix a bug where vt_fb_attach() success would be considered a failure
vt_fb_attach() currently always returns 0, but it could return a code
defined in errno.h. However, it doesn't return a CN_* code. So checking
its return value against CN_DEAD (which is 0) is incorrect, and in this
case, a success becomes a failure.
The consequence was unimportant, because the caller (drm_fb_helper.c)
would only log an error message in this case. The console would still
work.

vt(4): Change the terminal and buffer sizes, even without a font
This fixes a bug where scroll lock would not work for tty #0 when using
vt_vga's textmode. The reason was that this window is created with a
static 256x100 buffer, larger than the real size of 80x25.
Now, in vt_change_font() and vt_compute_drawable_area(), we still
perform operations even of the window has no font loaded (this is the
case in textmode here vw->vw_font == NULL). One of these operation
resizes the buffer accordingly.
In vt_compute_drawable_area(), we take the terminal size as is (ie.
80x25) for the drawable area.
The font argument to vt_set_border() is removed (it was never used) and
the code now uses the computed drawable area instead of re-doing its own
calculation.

Add EFI support to the installer. This requires that the kernel
provide a sysctl to determine what firmware is in use. This sysctl
does not exist yet, so the following blocks are in front of the
wheels:
- I've provisionally called this "hw.platform" after the equivalent
thing on PPC
- The logic to check the sysctl is short-circuited to always choose
BIOS. There's a comment in the top of the file about how to turn
this off.
If IA64 acquired a boot1.efifat-like thing (probably with very few
modifications), the same code could be adapted there.

Finish connecting up installer UEFI support. If the kernel was

r268256 (nwhitehorn):
After EFI support was added to the installer, it needed to allow
boot partitions of types other than "freebsd-boot" (in particular,
"efi"). This allows the removal of some nasty hacks for supporting
PowerPC systems, in particular aliasing freebsd-boot to apple-boot
on APM and an IBM-specific code on MBR.
This changes the installer to use the correct names, which also
breaks a degeneracy in the meaning of "freebsd-boot" that allows the
addition of support for some newer IBM systems that can boot from
GPT in addition to MBR. Since I have no idea how to detect which
those systems are, leave the default on IBM PPC systems as MBR for
now.
Make it possible to disable NOP-In PDUs by the iSCSI initiator by setting

Add script to setup bootable CD ISOs for both BIOS and EFI systems.

kernel support EFI too. In particular, the following two things are
required:
1. vt(9) be the default console driver
2. vt_efifb and vt_vga be able to coexist usefully in the same kernel
One other note here is that this requires newfs_msdos and mdconfig,
which is really ugly. NetBSD's makefs at least seems to support FAT
now. If that actually works, it should be imported and we can get rid

This change does the same for the "atf-sh library" by moving the atf-sh
interpreter from its public location in /usr/bin/ to the private location
in /usr/libexec/. Our build system will ensure that our own test programs
use the right binary, but users won't be able to depend on atf-sh by
"mistake".

Fix atf-sh's integration_test
With the move of atf-sh into /usr/libexec in r267181, some of the
tests in the integration_test program broke because they could not
execute atf-sh from the path any longer.
This slipped through because I do have a local atf installation in
my home directory that appears in my path, hence the tests could
still execute my own version.
Fix this by forcing /usr/libexec to appear at the beginning of the
path when attempting to execute atf-sh.
To make upgrading easy (and to avoid an unnecessary entry in UPDATING),
make integration_test depend on the Makefile so that a rebuild of the
shell script is triggered. This requires a hack in the *.test.mk files
to ensure the Makefile is not treated as a source to the generated
program. Ugly, I know, but I don't have a better way of doing this at
the moment. Will think of one once I address the TODO in the *.test.mk
files that suggests generalizing the file generation functionality.
