Add _BIX (Battery Information Extended) object support.
ACPI Control Method Batteries have a _BIF and/or _BIX object which
provide static properties of the battery. FreeBSD acpi_cmbat module
supported _BIF object only, which was deprecated as of ACPI 4.0.
_BIX is an extended version of _BIF defined in ACPI 4.0 or later.
As of writing, _BIX has two revisions. One is in ACPI 4.0 (rev.0) and
another is in ACPI 6.0 (rev.1). It seems that hardware vendors still
stick to _BIF only or _BIX rev.0 + _BIF for the maximum compatibility.
Microsoft requires _BIX rev.0 for Windows machines, so there are some
laptop machines with _BIX rev.0 only. In this case, FreeBSD does not
recognize the battery information.
After this change, the acpi_cmbat module gets battery information from
_BIX or _BIF object and internally uses _BIX rev.1 data structure as
the primary information store in the kernel. ACPIIO_BATT_GET_BI[FX]
returns an acpi_bi[fx] structure built by using information obtained
from a _BIF or a _BIX object found on the system. The revision number
field can be used to check which field is available. The acpiconf(8)
utility will show additional information if _BIX is available.
Although ABIs of ACPIIO_BATT_* were changed, the existing APIs for
userland utilities are not changed and the backward-compatible ABIs
are provided. This means that older versions of acpiconf(8) can also
work with the new kernel. The (union acpi_battery_ioctl_arg) was
padded to 256 byte long to avoid another ABI change in the future.
A _BIX object with its revision number >1 will be treated as
compatible with the rev.1 _BIX format.

Like the Linux pam_access(8) our pam_login_access(8) is a service module
for pam(3) that allows a administrator to limit access from specified
remote hosts or terminals. Unlike the Linux pam_access, pam_login_access
is missing some features which are added by this commit:
Access file can now be specified. The default remains /etc/access.conf.
The syntax is consistent with Linux pam_access.
By default usernames are matched. If the username fails to match a match
against a group name is attempted. The new nodefgroup module option will
only match a username and no attempt to match a group name is made.
Group names must be specified in brackets, "()" when nodefgroup is
specified. Otherwise the old backward compatible behavior is used.
This is consistent with Linux pam_access.
A new field separator module option allows the replacement of the default
colon (:) with any other character. This facilitates potential future
specification of X displays. This is also consistent with Linux pam_access.
A new list separator module option to replace the default space/comma/tab
with another character. This too is consistent with Linux pam_access.

valid, the block can simply be discarded.
The existing implementation tries to minimize the number of I/Os used.
For each cluster of swap blocks, it finds maximal runs of valid swap
blocks not resident in memory, and valid resident pages. During this
processing, the object lock may be dropped in several places: when
calling getpages, or when blocking on a busy page in
vm_page_grab_pages(). While the lock is dropped, another thread may
free swap blocks, causing getpages to page in stale data.

While this behavior may be desirable on Linux, it is not so on

from the env var. The only related bit really is that we need to be more
specific with the delimiter in the IPv6 case.

Merge r357970 from the clang1000-import branch:
Fix the following -Werror warning from clang 10.0.0 in hptmv(4):
sys/dev/hptmv/ioctl.c:240:4: error: misleading indentation; statement is not part of the previous 'if' [-Werror,-Wmisleading-indentation]
_vbus_p=pArray->pVBus;
^
sys/dev/hptmv/ioctl.c:237:10: note: previous statement is here
if(!mIsArray(pArray))
^
This is because the return statement after the if statement was not
indented. (Note that this file has been idented assuming 4-space tabs.)
