Left behind by commit a109de9 and commit dc73207, v4.3.33.
While there, drop a declaration of nonexistent function xedit() that
crept into commit afa65c8, v4.2.20.

Some callers have to second-guess shp_check_nav() to figure out
whether CN_LANDLOCKED means "too big to fit into the canal" or "can't
go there at all".
Fix that by returning d_navigation. CN_LANDLOCKED becomes either
NAV_CANAL or NAV_NONE, CN_CONSTRUCTION becomes either NAV_02 or
NAV_60, and CN_NAVIGABLE becomes NAVOK.
The CN_NAVIGABLE, ... codes are now unused. Drop them.

Print a message, send bulletin to owner. Affects ship key 'W', land
unit key 'W', and plane key 'f'. The message is necessary to give the
deity a chance to catch unexpected changes, e.g. a player modifying
retreat conditions right before the deity edits them. Watching out
for such changes is especially important with non-interactive edit.

Redundant information, but incredibly useful when you want to figure
out what happened without a (still nonexistent) journal replay tool.
The redundancy could help making a journal replay tool more robust.
To enable, set econfig key keep_journal to at least 2. Output events
are *not* flushed to disk immediately.
Why upgrade? I'm not a lawyer, but here's my take on the differences
to version 2:
* Software patents: better protection against abuse of patents to
prevent users from exercising the rights under the GPL. I doubt
we'll get hit with a patent suit, but it's a good move just on
general principles.
* License compatibility: compatible with more free licenses, i.e. can
"steal" more free software for use in Empire. I don't expect to steal
much, but it's nice to have the option.
* Definition of "source code": modernization of some details for today's
networked world, to make it easier to distribute the software. Not
really relevant to us now, as we normally distribute full source code.
* Tivoization: this is about putting GPL-licensed software in hardware,
then make the hardware refuse to run modified software. "Neat" trick
to effectively deny its users their rights under the GPL. Abuse was
"pioneered" by TiVo (popular digital video recorders). GPLv3 forbids
it. Unlikely to become a problem for us.
* Internationalization: more careful wording, to harden the license
outside the US. The lawyers tell us it better be done that way.
* License violations: friendlier way to deal with license violations.
This has come out of past experience enforcing the GPL.
* Additional permissions: Probably not relevant to us.

help avoid inclusion cycles. Sort include directives. Remove some
superflous includes.
