Implement most of timer_{create,settime,gettime,getoverrun,delete}
for amd64/linux32. Fix the entirely bogus (untested) version from
r161310 for i386/linux using the same shared code in compat/linux.
It is unclear to me if we could support more clock mappings but
the current set allows me to successfully run commercial
32bit linux software under linuxolator on amd64.

vt(4): Rewrite history scrolling
It's now possible to scroll up the 500 hard-coded lines of history, not
just a fraction of them. For instance, one can reach the top of the boot
process.
Sometimes, when scrolling or when changing the screen size (by changing
the font or loading a KMS driver for instance), one could see the
history cycling (old content appeared below latest lines). This is
fixed.
Now, when the resolution changes are more lines can be shown, the
displayed area is adjusted so that, if the screen was filled with
content before, it's filled with content after as well: more history
is visible, instead of having blank lines below the previously visible
content.

Workaround for receiving Voice Calls using the E1750 dongle from
Huawei. It might appear as if the firmware is allocating memory blocks
according to the USB transfer size and if there is initially a lot of
data, like at the answering machine prompt, it simply dies without any
apparent reason. The simple workaround for this is to force a zero
length packet at hardware level after every 512 bytes of data. This
will force the other side to use smaller memory blocks aswell.

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.

Keep tty_makedev as a function to preserve the KBI on 10-stable
(it is a macro in CURRENT). The changes for this are direct
commits to 10-stable.
r259549 (glebius):
- Rename tty_makedev() into tty_makedevf() and make it capable
to fail and return error.
- 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.
A race in tty_watermarks() still exist, since the latter drops
lock for M_WAITOK allocation. This will be addressed in separate
commit.
r259663 (glebius):
Move list of ttys handling from the allocating procedures, to the
device creation stage. A device creation can fail, and in that case
an entry already on the list will be freed.

Detailed commit list:
r269779:
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.

original window is another terminal or an X session. However, cnungrab()
doesn't vt-switch back to the original window currently.

r271250:
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.

r264978 (nwhitehorn):
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.
r265016 (nwhitehorn):
Finish connecting up installer UEFI support. If the kernel was
booted using EFI, set up the disks for an EFI system. If booted from
BIOS/CSM, set up for BIOS.
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.
