On some hardware the EFI system table is not in memory mapped in the
DMAP section. Rather than panic the kernel check if it is mapped and
return a failure if not from efi_phys_to_kva.

Some UEFI implementations place the system table in a runtime code
memory region. Include it in the DMAP so we can read it later.

The "void *stuff" (also called fstuff and dstuff) argument
was used by the Mac OSX port. For FreeBSD, this argument
is always NULL, so remove it to clean up the code.
This commit gets rid of "stuff" for nfscl_postop_attr().
Future commits will do the same for other functions.
Add PS_MODE_NO_KINFO_PROC cmd modifier that indicates that neither
process list should be queried from the kernel, nor list of pids or `-a`
switch provided on the command line to filter the output.
This is intended for use by commands that query information not
neccessary attributed to specific process.

For now, only for sysctl target. This is not a new situation, for
instance kstacks also work for sysctl only.

reporting the shapshot of the active advisory locks.
A new VFS ops method vfs_report_lockf if provided in the mount point
op table. If it is NULL, as it is currently for all existing
filesystems, vfs_report_lockf() function is used, which gathers
information from the standard implementation inside kern/kern_lockf.c.
Filesystems implementing its own locking (NFSv4 as example) can provide
a custom implementation.

The UFS-specific struct inode cannot be used in generic advisory lock
code. It was probably used as a shortcut for the debugging, as the
remnants of the code around it indicates.
Use somewhat more verbose and less concentrated, but universal,
VOP_PRINT(), where needed.

Right now it is incidentally declared in sys/lockf.h, which will be
corrected shortly.

This fixes a performance problem where poudriere -j 104 keeps remounting
filesystems, which induce wanting to signal mountd, if running. The
current code tries to do it by creating the pidfile in /var/run and
unlinking it if the operation succeeds, inducing contention against
anything doing an exec as it tries to look up /var/run/ld-elf.so.hints
