6034024dad Add -z "TOS" option to ping6, to test DSCP/ECN values
ping has the option to add the (deprecated) TOS byte
using the -z option. Adding the same option, with the
same (deprecated) Traffic Class Byte (nowadays actually
DSCP and ECN fields) to ping6 to validate proper QoS
processing in network switches.

af14123601 Make ping6(1) return code consistent with the man page.
When every sendto() call originated by ping6(1) fails, current code always
 returns 2 ("transmission was successful but no responses were received")
 which is incorrect. Return EX_OSERR instead as in many cases it indicates
 some kernel-level problems.

5ab1c5846f Add Makefile.depend.options
Leaf directories that have dependencies impacted
by options need a Makefile.depend.options file
to avoid churn in Makefile.depend

DIRDEPS for cases such as OPENSSL, TCP_WRAPPERS etc
can be set in local.dirdeps-options.mk
which can add to those set in Makefile.depend.options

See share/mk/dirdeps-options.mk

62da1eef7f ping6: Fix dnsdecode() bug introduced by r350859
Revision 350859 removed level of indirection that was needed for setting the
caller's `cp' pointer. dnsdecode() uses return value to indicate error or
success. It returns pointer to a buffer holding a decompressed DNS name or
NULL. The caller uses that value only to find out the result, not for accessing
the buffer.

We use the return value to propagate the new value of `cp' pointer to
the caller instead of using an output argument.

8a16b7a18f General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
