There is one capability explicitly documented in gettytab(5) as stupid: he.
And it is indeed. It was meant to facilitate system hostname modification,
but is hardly usable in practice because it allows very limited editing
(e.g., it depends on a particular hostname length, making it non-generic).
Replace it with simple implementation that treats ``he'' as POSIX extended
regular expression which is matched against the hostname. If there are no
parenthesized subexpressions in the pattern, entire matched string is used
as the final hostname. Otherwise, use the first matched subexpression.
If the pattern does not match, the original hostname is not modified.
Using regex(3) gives more freedom, does not complicate the code very much,
and makes a lot more sense, in turn making ``he'' less stupid and actually
useful (e.g., it is now possible to obtain node or domain names from the
original hostname string, without knowing it in advance).

Some PCI-e bridges report that they support HotPlug in the slot
capabilities but do not report support for Data Layer Active events
in the link capabilities register. These bridges do not work correctly
when HotPlug is used. Further, while the description of HotPlug in
the spec does not mention that DL active events are required, the
description of the link capabilities register says that DL active is
required for HotPlug. Thanks to Dave Baukus for finding that language
in the spec.

As noted in r313008, the underlying issue was that geom_gate device
creation wasn't created at ggatel command completion, but some short
time after. ggatec(8) employs similar logic when creating geom_gate(4)
devices.
Switch from retry loops (after the ggatec/dd write calls) to
wait_for_ggate_device function calls after calling ggatec(8) instead
to detect the presence of the /dev/ggate* device, as this function is
sufficient for determining whether or not the character device is ready
for testing
While here, use atf_check consistently with all dd calls to ensure that
data output is as expected.

Historically AM335x LCDC driver used non-standard "hdmi" property to
refer to HDMI framer. There is no such thing in upstream DTS, so to
handle both cases fallback to bindings described in
bindings/media/video-interfaces.txt in Linux documentation.
We still make some assumptions that are not universally true: we
assume that if remote endpoint is available it's going to be HDMI
framer. Which is true for AM335x-based devices currently supported
but may be not true for some custom hardware.

Recommit: Stop intercepting some malloc-related functions on FreeBSD
and macOS
Summary:
In https://bugs.freebsd.org/215125 I was notified that some configure
scripts attempt to test for the Linux-specific `mallinfo` and
`mallopt` functions by compiling and linking small programs which
references the functions, and observing whether that results in
errors.
FreeBSD and macOS do not have the `mallinfo` and `mallopt` functions,
so normally these tests would fail, but when sanitizers are enabled,
they incorrectly succeed, because the sanitizers define interceptors
for these functions. This also applies to some other malloc-related
functions, such as `memalign`, `pvalloc` and `cfree`.
Fix this by not intercepting `mallinfo`, `mallopt`, `memalign`,
`pvalloc` and `cfree` for FreeBSD and macOS, in all sanitizers.
Also delete the non-functional `cfree` wrapper for Windows, to fix the
test cases on that platform.

The disk_* and part_* api is using 64bit values for media size and
offsets. However, the current api is using off_t type, which is signed
64-bit int.
In this context the signed media size does not make any sense, and
the offsets are used to mark absolute, not relative locations.
Also, the data from GPT partition table and some other sources is
already using uint64_t data type, so using signed off_t can cause sign
issues.

changes are done:
Simple cstyle changes in env.c
Moved efi variable related commands from loader/main.c to libefi/env.c
Did create function to set "efi-version" environment variable in env.c.
This function does serve two purposes: for first a small clean up of the
loader main(), and for second, it does replace the otherwise unused
efi_variable_support hack.
A bit of cleanup of ficl backend functions. The TEST_MAIN has no meaning,
and removed few memory leaks.
The forth code is updated to use "efi-version" variable, instead of ficl

Freescale added the E.D profile to e500mc and derivative cores. From
Freescale's EREF reference manual this is enabled by a bit in HID0 and should
otherwise default to traditional debug. However, none of the Freescale cores
support that bit, and instead always use E.D. This results in kernel panics
using the standard debug on e500mc+ cores.
Enhanced debug allows debugging of interrupts, including critical interrupts,
as it uses a different save/restore registers (srr*). At this time we don't use
this ability, so instead share the core of the debug handler code between both
handlers.
