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
git-controlled. Fails when the build tree is separate. Fix it to
read $srcdir/.tarball-version.
The occurence in Make.mk isn't wrong, because VPATH applies there.
Change it anyway, for consistency and a bit of extra robustness.

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 made src/scripts/tarball generate .tarball-version and
.dirty-stamp. Hardcoding it like that there is a bit ugly.
Move it into a separate tweak script that is run right before tar.
We'll tweak some more in the next commits.

Version information is in output of commands version, xdump version,
and in program output for option -v. Looks like this:
Wolfpack Empire 4.3.33
The version number is defined in configure.ac, and incremented
manually. It identifies only the base release (here: 4.3.33). Fine
when this is an unmodified released version. Pretty much useless
during development.
Add a suffix to the version number that describes it further:
V Unmodified release V (same as before)
V.N-H Modified release built from a clean git tree
N is the number of additional commits, and
H is the abbreviated commit hash
V.N-H-dirty Same, but the working tree is dirty
V-dirty Modified release built from a tarball
A git tree is clean when the contents of its files are unchanged.
Changing only the their timestamps doesn't count. It does count when
building from a tarball, because tracking contents isn't implemented
there.
Also use this suffixed version for tarball names.
The version reported by configure is fixed at configure generation
time, i.e. it is usually out of date during development. Ensuring a
release tarball contains one with a current version is manual for now.
Running autoconf -f should do the trick.
Elsewhere, the version is determined at build time, so it is always
current.
Dirty tracking isn't implemented in the standalone client build. If
you start with a clean tarball, the version will not change from V to
V-dirty when you build with modifications.
Steal build-aux/git-version-gen from autoconf 2.69 to help with
computing the version string.

AX_LIB_READLINE tries to cope with systems where readline lacks
history support, or lacks headers, or needs headers included in
unorthodox ways. It puts six HAVE_ macros into config.h, and its
usage example takes 24 lines of code just to include two headers.
Way too complicated for my taste. Replace with new MY_LIB_READLINE,
which succeeds only when you have a sane readline, and then defines
*one* macro: HAVE_LIBREADLINE.

Readline provides fancy command line editing such as <Arrow Up> for
previous commands and CTRL+A to jump to the beginning of the line.
This patch does not add any completion on <tab> key, a TODO, if you
will.
A new command line flag, -H, turns on saving the history to disk.
This may have security implications on shared computers, as all
commands are saved as-is. Thus "change re 1234" would be logged
directly to the file.

Rebase on top of preparatory work, fix a few bugs, and tidy up:
* Update the standalone client build, too.
* Fix the Windows build.
* Keep command line options sorted case-insensitively.
* Error out when $HOME is unset and getpwuid() fails, just like we do
for $LOGNAME.
* Give @input_from_rl, @has_rl_input static linkage.
* @has_rl_input is a flag, not a counter, set and test it accordingly.
* Save all input in history, not just commands. Martin's attempt to
recognize commands works only as long as the server sends prompts
faster than the user sends input. Drop that part, and update commit
message accordingly.
* Fix recv_input() not to truncate value of strlen() to int, and to
use memmove() for updating @input_from_rl in place.
* Clean up whitespace in a few places.
* Tweak commit message.

When AC_PROG_CC detects GCC, Make.mk adds a bunch of flags to CFLAGS.
Works only for flags that any version of gcc in use accepts.
Instead, make configure add the flags that actually work to CFLAGS.
This will let us add flags that work only for some compilers.
The new autoconf macros are from autoconf-archive v2015.02.24.
Unfortunately, AX_APPEND_COMPILE_FLAGS doesn't work reliably for
-Wno-*: gcc complains about unknown -Wno-foo only when other
diagnostics are being produced. Test -Wfoo instead of -Wno-foo, and
rename to MY_APPEND_COMPILE_FLAGS.

Here's why removing override is a good idea. The variable assignment
should already override anything Make may find in its environment.
All "override" does is protect against unwise make arguments.
"info make" says:
The `override' directive was not invented for escalation in the war
between makefiles and command arguments. It was invented so you can
alter and add to values that the user specifies with command
arguments.
Thus, override is ill-advised here.

Since subjects were added in Empire 2, we've always picked them up
from .SA requests. If you mistype a subject there, you get a "is a
NEW subject" warning, and incorrect subject pages. When building a
pristine tree, you get bogus "is a NEW subject" warnings for all
subjects. If you somehow delete the generated subjects.mk, but not
the generated subject files, the build breaks.
Declare subjects in Make variable subjects. Drop generated makefile
subject.mk.
Treat unknown topics in .SA arguments as errors. This replaces the
"$subj is a NEW subject" warning.
Treat subjects without member pages as errors. This replaces the "The
subject $subj has been removed" warning.
Safer and simpler.
We used to do all the info indexing work in info.pl: find subjects,
create subjects.mk (to tell make the list of subjects), the subject
pages, and TOP.t. Worked, but touching an info page triggered a full
rebuild of all subject pages and TOP.t.
Commit 2f14064 (v4.3.0) tried to avoid that by splitting info.pl into
findsubj.pl, mksubj.pl, mktop.pl. findsubj.pl puts not just the
subjects into subjects.mk, but also make rules for the subject pages,
to guide their remaking. mksubj.pl creates a single subject page.
mktop.pl creates TOP.t.
Unfortunately, this doesn't work so well. Since subjects.mk doesn't
exist in a virgin tree, we use -include. Unwanted consequence:
findsubj.pl failure doesn't stop make. Moreover, the complex make
machinery breaks down when info sources get removed or subjects get
dropped.
Go back to the old method, except keep mktop.pl separate, as that part
works just fine, and use simpler make rules. mksubj.pl now creates
subjects.mk and all subject pages, like info.pl did.
This effectively reverts most of commit 2f14064. I'll address the
excessive rebuilding of subject pages in a different way shortly.
Remaking config.h and config.h.in updates the target only when its
contents actually changes. This is important, because after updating
config.h we need to recompile everything.
The make rules to do that are straight from the Autoconf manual. But
they don't work: the rules that connect config.h and config.h.in to
stamp-h and stamp-h.in don't have recipes. Since make doesn't have an
implicit rule either, it concludes that the target remains unchanged.
It still updates the prerequisites. The recipe for updating the stamp
files then change the the targetes behind make's back. Make misses
the change of config.h and/or config.h.in, and we get an incomplete
rebuild.
The rules need empty recipes instead. This Autoconf manual was fixed
accordingly in autoconf.git commit 6b42b38.
Just a smoke test so far, extracted from src/scripts/nightly/. This
makes the existing smoke test more easily accessible. Noteworthy
differences:
* Instead of patching the code to make output more stable, postprocess
the output to normalize it.
* Compare actual results to expected results instead of the previous
test run's results.
* Much faster. The old test harness used sleep liberally to "ensure"
things always happen in the same order.
Known shortcomings:
* The smoke test hangs when the server fails to complete startup, or
fails to terminate.
* Normalization of xdump hardcodes columns instead of getting them
from xdump meta.
* Normalization of time values in xdump is an ugly hack.
* xdump meta column type isn't normalized. Actual values can vary
between systems, because the width of enumeration types is
implementation-defined. The smoke test works only when they're
represented as int, which is the case on common systems.
* Currently expected to work only with thread package LWP and a
random() that behaves exactly like the one on my development system,
because:
- Thread scheduling is reliably deterministic only with LWP
- The PRN sequence produced by random() isn't portable
- Shell builtin kill appears not to do the job in MinGW
- The Windows server tries to run as service when -d isn't
specified
Further work is needed to address these shortcomings.
Getting C programs behave exactly the same on all systems is hard.
We'll likely run into system-dependent differences that upset the
smoke test. Floating-point computation seems particularly vulnerable.
Instead of updating src/scripts/nightly/ to use "make check", retire
it. It hasn't been used in quite a while. Investing more into our
homegrown auto-builder doesn't make sense, as canned auto-builders
such as Travis CI and Jenkins are readily available.
The shell scripts src/scripts/nightly/tests/?? become Empire batch
files tests/smoke/. The shell scripts are actually shell boilerplate
around Empire batch files. To make sure git recognizes the move, this
commit moves them unchanged. tests/smoke-test strips the boilerplate
before it feeds the batch files to the client. The next commit will
get rid fo that.
