gcc 4.9 added support for new alignment attribute alloc_align:
The alloc_align attribute is used to tell the compiler that the function
return value points to memory, where the returned pointer minimum
alignment is given by one of the functions parameters. GCC uses this
information to improve pointer alignment analysis.
This attribute is not (yet) available on clang.
vt_is_cursor_in_area needs to return true if any part of the mouse
cursor is visible in the rectangle area. Replace the existing test with
a simpler version of a test for overlapping rectangles.

Fix a missing .h and change the recommended include for the POSIX2008 functions from xlocale.h to locale.h. Including xlocale.h is for legacy / Darwin compatibility so should not be encouraged.
It would previously call into some unfinished Solaris compatibility code and
return without actually calling panic(9). The compatibility code is
unneeded, however, so just remove it and have dtrace_panic() call vpanic(9)
directly.

On RPI(2) the DTB is loaded and modified by firmware and then handed to
kernel via U-Boot and ubldr.
The RPI firmware adds (or modify) a few valuable data to the in memory
DTB, like:
- System memory;
- Ethernet MAC address;
- framebuffer settings;
- Board serial and revision;
- clock-frequency for most of devices.
The 'pwr' LED is connected to GPIO pin 35 (active high) and the 'act' LED

Remove the GPIO pin 47 from reserved pins list, previously it was used to

GPT scheme. UEFI needs to know the unique partition GUID
with GPT, which changes each time. Specifically, the QEMU
EFI BIOS file has this hard-coded.[1]
Since the GPT labels are now unavailable, unconditionally
label the root filesystem as 'rootfs' with newfs(8), since
it does not hurt anything anywhere else. For the arm64 case,
'/' is mounted from /dev/ufs/rootfs; for all other VM images,
'/' is mounted from /dev/gpt/rootfs.
Unfortunately, since the /dev/gpt/swapfs label is also lost,
set NOSWAP=1 for the arm64/aarch64 images. This is temporary,
until I figure out a scalable solution to this. But, a certain
piece of softare was written "very fast", and ended up living
for 15 years. We can deal with this for a week or so.

(type 1 and type 2) as well as leaf devices (type 0). In particular,
this allows the existing PCI bus logic to save and restore capability
registers such as MSI and PCI-express work for bridge devices rather than
requiring that code to be duplicated in bridge drivers. It also means
that bridge drivers no longer need to save and restore basic registers
such as the PCI command register or BARs nor manage powerstates for the
bridge device.
While here, pci_setup_secbus() has been changed to initialize the 'sec'
and 'sub' fields in the 'secbus' structure instead of requiring the pcib
and pccbb drivers to do this in the NEW_PCIB + PCI_RES_BUS case.
