Since commit 1ec9b94, we derive the version number from git tags with
build-aux/git-version-gen. When a shallow clone doesn't include a
suitable tag, this fails, and make refuses to build anything. Since
Travis uses git-clone --depth=50, it'll break as soon as we've got
more than 50 commits since the last release.
Support arbitrarily shallow clones for limited purposes like testing
by falling back from a proper V.N-H version number to UNKNOWN-H.
To guard against use of such builds for other purposes, log a warning
on server startup, and print one on player login.

configure reads .tarball-version when the source tree isn't

read $srcdir/.tarball-version.

The build fails on Travis since we require autoconf 2.69 (commit
db055a). Travis still defaults to Ubuntu Precise, and Precise's
autoconf is too old. We could revert commit db055a and rely on Travis
to keep things working with old autoconf. But Precise reached end of
life a couple of months ago, and I suspect it's only a matter of time
until Travis drops it, too.
Fix the build on Travis by requesting Trusty. Its end of life is
planned for April 2019.

As commit 1ec9b94 explains, the version reported by configure is fixed
at configure generation time. "make dist" happily distributes a stale
one. Not terrible, because all that's stale is the output of
configure --version, just embarrassing.
Make gen-tarball-version fail when the configure --version doesn't
match the tarball version.

Commit 1ec9b94 broke regeneration of configure for dist-client: it
uses .tarball-version, which exists only in the tarball, not in the
source tree.
Generating the client's autoconf stuff into the source tree is a
questionable idea anyway, as it won't run there. Generate it while
building the tarball instead.
Bonus: doesn't distribute a useless .dirty-stamp.

Commit 1ec9b94 normalized version numbers in test output to 4.3.34,

become 4.4.0 meanwhile. Update the normalization just to avoid

The .NA header promises information on "Clients which communicate well
with the Empire4 Server". The page doesn't really deliver. It talks
about client support for asynchronous notifications. It stopped
listing separate client projects in 4.0.7 (1997). Not mentioning such
clients isn't just outdated, it's actively misleading.
Perhaps an up-to-date info page on clients would be useful, but I
can't write one right now. Delete.
Loses a bit of information for client developers that was tacked on in
4.0.7: pointers to dump commands, and an explanation of timestamps. I
trust client writers can find "info xdump" without this.

contact: Move contact state from struct natstr to contactstr
Contact state is relatively bulky: it's a big chunk of struct natstr,
and adds almost 200 bytes per country to xdump nat for deities.
Contact changes rarely. Since we avoid unnecessary updates, it
doesn't change at all unless option HIDDEN is enabled. Rewriting it
to disk on every nation update and retransmitting it in every deity
xdump nat is wasteful.
To avoid this waste, move contact state to its own struct contactstr.
This is of course an xdump compatibility break. We're not maintaining
xdump compatibility in this release.

A country must always be in contact of itself when option HIDDEN is
enabled. The code ensures this by establishing contact whenever a
player logs in, in init_nats(). This is not the proper place. Game
state should be initialized in empfile's oninit() callback, in this
case nat_oninit(). Do that, and drop the putcontact() from
init_nats().
Note that option LOSE_CONTACT only affects contact to other countries:
agecontact() doesn't age the country's contact to itself.
Use the opportunity to initialize contact so that getcontact() works
even when HIDDEN is disabled. Just cleanup, it isn't actually called
then.

When option LOSE_CONTACT is enabled, contact is lost after a few
updates. The remaining number of updates is to be decremented by one
each update. However, it's actually decremented every time an active
nation is updated. This makes countries lose contact much too fast,
typically every update. Broken in commit ac25058, v4.3.0.

Interactive edit shows what can be edited, with edit keys and current

contact information like "Countries contacted: 1(6) 2(6) 4(5) ".
Lists the numbers of contacted countries and, in parenthesis, how many
updates contact is going to last if option LOSE_CONTACT is enabled.
The line was added along with option HIDDEN in Empire 2. As long as
editing contact isn't implemented, it doesn't belong here. Drop it.
If deities need contact information, we'll have to show it elsewhere.

Military in land units count. Even when the land unit is loaded on a
ship or land unit. Questionable, because unload need not be possible.
Checking whether unload would be possible is not worth the trouble
here, simply ignore embarked land units.

as the update's distribution and delivery.

Infrastructure requires lcms and hcms to build. The build materials
are exposed as infrastructure columns lcms, hcms (struct sctintrins
members in_lcms, in_hcms). They are per point of efficiency. In
contrast, sector and unit build materials are defined for 100%.
We want to define build materials for 100% now, for flexibility and
consistency, and we want to optionally support more build materials in
the future. Replace members in_lcms and in_hcms by array in_mat[],
and provide selectors l_build and h_build.
Additionally provide selectors for all other item types, with value
zero, to help clients prepare for future additional materials. Use

config: Define infra build cost and mobility use per 100%
Infrastructure build cost is defined by infra column dcost (struct
sctintrins member in_dcost). It's the cost per point of efficiency.
In contrast, sector and unit build cost is defined for 100%, by
sect-chr, ship-chr, plane-chr, land-chr, nuke-chr column cost.
Switch to build cost per 100%, for flexibility and consistency:
replace struct sctintrins member in_dcost by in_cost, and selector
dcost by cost.
With cost values that aren't multiple of 100, the build cost may have
to be rounded. Do this exactly like we round sector build cost: the
amount is limited to money * 100 / cost rounded down, but the money
charged is actual amount * money / 100 rounded randomly.
Do the same for mobility use: replace struct sctintrins member
in_mcost by in_bmobil, and selector mcost by bmobil, with similar
rounding.
