This version adds a command to dc to query whether extended registers
are enabled or not.
(cherry picked from commit 61e1a12bb6c3bfdb0a4e499c88e8eaa2b548e427)
The routine is used as a general event-limiting routine in places which
have nothing to do with packets.
Provide a define to keep everything happy.

Fixes: 6a836ea741 ("config(8): Remove obsolete 'config' directive.")
For compatibility with glibc. The previous code would trigger a division
by zero in roundup() and terminate. Instead, just pass through to
malloc() for align == 0.

This file defines a small API to be used by other drivers. If any of
these functions are called before the bcm_dma device has attached we
should handle the error gracefully. Fix a formatting quirk while here.

The sdhci_bcm driver attach routine relies on bcm_dma already being
attached, in order to allocate a DMA channel. However, both drivers
attached at the default pass so this is not guaranteed. Newer RPI
firmware exposes this assumption, and the result is a NULL-dereference
in bcm_dma_allocate().
To fix this, use BUS_PASS_SUPPORTDEV for bcm_dma.

The Kasan tests show the nfsrvd_cleancache() results
in a modify after free. I think this occurs because the
nfsrv_cleanup() function gets executed after nfs_cleanup()
which free's the nfsstatsv1_p.
This patch makes them use the same subsystem and sets
SI_ORDER_FIRST for nfs_cleanup(), so that it will be called
after nfsrv_cleanup() via VNET_SYSUNINIT().
The patch also sets nfsstatsv1_p NULL after free'ng it,
so that a crash will result if it is used after free'ng.

ping -R (F_RROUTE) will loop at ping.c:1381 until it segfaults or
the unsigned int hlen happens to be less than the size of an IP header:

Segmentation fault
The reason for this is while looping through loose source routing (LSRR)
and strict source routing (SSRR), hlen will become smaller than the IP
header. It may even become negative. This should terminate the loop.
However, when hlen is unsigned, an integer underflow occurs becoming a
large number causing the loop to continue virtually forever until hlen
is either by chance smaller than the lenghth of an IP header or it
segfaults.

As the comment says it probably does not matter but use a local
variable to track state under lock so we can return the last known
good state of what we thought we were operating under after unlocking.
Likely no functional changes.

This drops function `getexecname()` redirection.
Historically `getexecname()` is a compatibility definition. Since
openzfs has its own implementation of function `getexecname()` in libspl
and has been merged into base, the compat header file stdlib.h is
no longer needed and should not be used.
Also without this fix libspl will end up an incompatible version of
`getprogname()` with libc. In particular, if zfs is enabled, programs
such as pgrep in /rescue can be wrongly statically linked with libspl
and will not function properly.
