Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Approved by: re (implicit)

Bump shared libraries version numbers in preparation for 9.0.
This time, only libraries which ABI has been changed compared to
stable/8, are bumped.

Unbreak the build by temprorarily not using include directives in
bsnmpd(1)' def files, until bsd.snmpmod.mk & Makefiles are fixed to
pass proper include path flags to gensnmptree.

Catch up with the import of bsnmp-1.11. Add a couple of new

Finish repo-copy of lib/libbsnmp/modules to usr.sbin/bsnmpd/modules.
These modules are modules for the daemon, not for the library so
they should be where the daemon is.

For variables that are only checked with defined(), don't provide

Link to the build again. The problem was that we need a new
gensnmptree for the .def file to parse. This was fixed in
Makefile.inc1.

Again something bad is happening so comment out the ATM module.

Now, after the import of NgATM-1.1, re-enable the atm module.

Disable the snmp_atm module until the source gets fixed. This will unbreak
this portion of the build.

Link the snmp_atm module to the build unless NOATM is defined.

Now that gensnmptree can read and merge more than one tree make

trees.

A module for bsnmpd(1) that exports a MIB that contains information about
the local ATM interfaces and allows to change some parameters via SNMP.

Add the right CFLAGS to show that we have err.h, getaddrinfo and strlcpy.
Add support.c to the list of source files.

Move libbsnmp.so to /lib so that it is available to atmconfig.
At the moment the only dependency on this library is bsnmpd.

Bump the shared library version number for the bsnmp v1.6 import
because of incompatible interface changes.

Put the name of the module first in the list of all .Nm calls with
argument. This makes the output of calling .Nm without an argument
more senseful later on.

Compare with 0 if comparing an integer, not with NULL.

Move the SNMP MIBs and tree definitions from /usr/share/bsnmp to
/usr/share/snmp. This mirrors the use of /usr/local/share/snmp and
makes also more sense when non-bsnmp-specific MIBs go in.

Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror)
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).

There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.

Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

Rename the MIBS makefile variable to BMIBS so that it does not conflict
with the environment variable MIBS that is used by net-snmp.

Create the OID and tree files while building the modules and the daemon
instead of creating them by hand and storing them in the CVS tree. Add
gensnmptree to the bootstrap tools (it is used to generated these files).
This simplifies the update procedure.

Fixed the fatal bug: CFLAGS should be added to, not overridden.
This prevented CPU and optimization flags to be added here.

Replace all uses of the old netgraph constants NG_*LEN by the new
constants NG_*SIZ that include the trailing NUL byte. This change
is mostly mechanical except for the replacement of a couple of snprintf()

Add an empty definition of the MIBS variable so that the makefile does
not try to use a MIBS definition from the environment.

Fix the build by adjusting the include directives. The problem was
