This is not a functional change but a preperation for the upcoming
DTrace support. It is necessary to change the state in one
logical operation, even if it involves clearing the sub state
SHUTDOWN_PENDING.

The length of SCTP packets is always a multiple of 4. Therefore,
ensure that the MTUs used are also a multiple of 4.

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.
This patch allows the MTU stored in the hostcache to be used as an
initial value for SCTP paths. When an ICMP PTB message is received,
store the MTU in the hostcache.

However, I was not able to reproduce this when using the code in the kernel.
Thanks to Eugen-Andrei Gavriloaie for reporting the issue and proving detailed
information to find the root of the problem.
