sys: Drop redundant NULL check before m_freem(9)

m_freem(9) safely has accepted NULL argument at least since 4.2BSD:
https://www.tuhs.org/cgi-bin/utree.pl?file=4.2BSD/usr/src/sys/sys/uipc_mbuf.c

Introduce m_set_rcvif and m_reset_rcvif

The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.

change nfs_boot_sendrecv to take sockaddr_in * instead of mbuf *

fixes m_serv (single mbuf leak) leak in kern/subr_tftproot.c

when calling nfs_boot_sendrecv pass NULL for pointers instead of 0

	sys/nfs/krpc_subr.c: revision 1.39
	sys/nfs/nfs_bootdhcp.c: revision 1.53
m_pullup() is called in rcvproc callback functions,
so nfs_boot_sendrecv() should keep track of the head of mbuf chain.

Update haad-dm branch to haad-dm-base2.

Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

change nfs boot behaviour to automatically try next boot method if boot information are incomplete to succeed.
That way, it is possible combine static and dhcp boot:
  For example, to boot diskless you can specify the nfs-server and the rootpath statically. All other information will be taken via dhcp.

Patch has been presented on port-xen, tech-kern and tech-net:

Eliminate several uses of `curproc' from the socket-layer code and from NFS.

Add a new explicit `struct proc *p' argument to socreate(), sosend().
Use that argument instead of curproc. Follow-on changes to pass that
argument to socreate(), sosend(), and (*so->so_send)() calls.
These changes reviewed and independently recoded  by Matt Thomas.

Changes to soreceive() and (*dom->dom_exernalize() from Matt Thomas:
pass soreceive()'s struct uio* uio->uio_procp to unp_externalize().
Eliminate curproc from unp_externalize.   Also, now soreceive() uses
its uio->uio_procp value, pass that same value downward to
((pr->pru_usrreq)() calls for consistency, instead of (struct proc * )0.

Similar changes in sys/nfs to eliminate (most) uses of curproc,
either via the req-> r_procp field of a struct nfsreq *req argument,
or by passing down new explicit struct proc * arguments.

Reviewed by: Matt Thomas, posted to tech-kern.
NB: The (*pr->pru_usrreq)() change should be tested on more (all!) protocols.

remove duplicated snprintf(vci, ...)

kill sprintf, use snprintf

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it.  This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

Bump the kernel rev up to 1.6V

Add MBUFTRACE kernel option.
Do a little mbuf rework while here.  Change all uses of MGET*(*, M_WAIT, *)
to m_get*(M_WAIT, *).  These are not performance critical and making them
call m_get saves considerable space.  Add m_clget analogue of MCLGET and
make corresponding change for M_WAIT uses.
Modify netinet, gem, fxp, tulip, nfs to support MBUFTRACE.
Begin to change netstat to use sysctl.

It is misleading that the kernel outputs "DHCP server:" followed by
the value of "next-server" from the DHCP (or BOOTP) reply.  This is
not the DHCP server's IP address (except by chance), so instead of
"server" make it print "next-server".

print diskless boot related IP addresses in dot notation

restructure the diskless NFS boot code to keep track of the used
interface and the address allocated, to roll everything back if the
mount fails:
-put an interface pointer into "struct nfs_diskless" to have it
 available for cleanup, don't pass it around anymore where the
 "struct nfs_diskless" is already passed
-add a "cleanup" function which shuts the interface down
-in the protocol-specific parts, either return with "everything
 ready" or "completely shut down"
-use common functions for interface initialization and shutdown
-add a function to delete all routes associate to an interface
 (why is this necessary and not done by ~IFF_UP?)
