James Tucker 9206e766ed net/packet: cleanup IPv4 fragment guards
The first packet fragment guard had an additional guard clause that was
incorrectly comparing a length in bytes to a length in octets, and was
also comparing what should have been an entire IPv4 through transport
header length to a subprotocol payload length. The subprotocol header
size guards were otherwise protecting against short transport headers,
as is the conservative non-first fragment minimum offset size. Add an
explicit disallowing of fragmentation for TSMP for the avoidance of
doubt.

Will Norris 71029cea2d all: update copyright and license headers
This updates all source files to use a new standard header for copyright
and license declaration.  Notably, copyright no longer includes a date,
and we now use the standard SPDX-License-Identifier header.

This commit was done almost entirely mechanically with perl, and then
some minimal manual fixes.

Updates #6865

Brad Fitzpatrick b560386c1a net/packet, wgengine, tstun: add inter-node TSMP protocol for connect errors
This adds a new IP Protocol type, TSMP on protocol number 99 for
sending inter-tailscale messages over WireGuard, currently just for
why a peer rejects TCP SYNs (ACL rejection, shields up, and in the
future: nothing listening, something listening on that port but wrong
interface, etc)
