MFC r350957:
Increase YPMAXRECORD to 16M to be compatible with Linux.

Sponsored by: Mellanox Technologies

Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

In usr.sbin/rpc.ypupdated/yp_dbupdate.c, since intmax_t is signed, just
like time_t, better use %jd instead of %ju. Strangely enough, neither
gcc, clang nor gcc 4.6 warn about this discrepancy...

MFC after: 1 week

In usr.sbin/rpc.ypupdated/yp_dbupdate.c, include stdint.h, so intmax_t
is known, otherwise it won't build.

In usr.sbin/rpc.ypupdated/yp_dbupdate.c, use the appropriate printf
length modifier for time_t (after casting it to intmax_t).

Remove definition of struct dom_binding, it's non-standard C code and
unnecessary since src/include/rpcsvc/ypclnt.h's revision 1.10.

Include <stdlib.h> for exit() and abort() prototypes.

Apply the following mechanical transformations in preparation for
ansification and constification:

s{\s+__P\((\(.*?\))\)}{$1}g;
s{\(\s+}{\(}g;
s{\s+\)}{\)}g;
s{\s+,}{,}g;
s{(\s+)(for|if|switch|while)\(}{$1$2 \(}g;
s{return ([^\(].*?);}{return ($1);}g;
s{([\w\)])([!=+/\*-]?=)([\w\(+-])}{$1 $2 $3}g;
s{\s+$}{\n};g

Also add $FreeBSD$ where needed.

Fix the type of the NULL arg to execl()

Idea from: Theo de Raadt <deraadt@openbsd.org>

$Id$ -> $FreeBSD$

Use err(3). Remove multiply defined Id string.

This commit was generated by cvs2svn to compensate for changes in r26236,

Import rpc.ypupdated.

This program still needs work but does compile and run. It also
needs a man page.
