Looks like an attempt was made to have .SA point to info pages for
significantly changed things. It wasn't done consistently, though,
and it's impractical for Empire 4. Drop these references, and keep
only "Server".

The .NA show up in "info Server", like this:
Chainsaw ! Changes from KSU Empire to Chainsaw code
Empire2 ! Changes from the Chainsaw server to the Empire2 Server
Empire3 Changes from the Empire2 server to the Empire3 Server
Empire4 ! Changes from the Empire3 server to the Empire4 Server
[...]
Merc Changes from KSU code to Merc code
Old-empire ! Differences from 1.2 to UCB Empire
Tweak them to look like this:
Chainsaw ! Changes from KSU Empire to Chainsaw (1992-93)
Empire2 ! Changes from Chainsaw to Empire 2 (1995)
Empire3 Changes in Empire 3 (1995-96)
Empire4 ! Changes in Empire 4 (1996-present)
[...]
Merc Changes from KSU code to Merc code (1992)
Old-empire ! Differences from 1.2 to UCB Empire
The first paragraph of Empire2.t refers to "the new Empire 2" server.
Drop "new", because it clearly ain't anymore. Same for Empire3.t.
The first paragraph of Empire4.t claims "several changes/fixes" have
been made. Umm, that's only tenuously connected to reality by now.
Rewrite the paragraph.

Ken Stevens stopped maintaining Empire many years ago, but "info
Empire2" and "info Empire3" still direct users to him. Drop that.

(all): Depend on info.
Flatten info directory. This undoes the move to one subdirectory per
chapter, which was done during Empire 2. The structure doesn't buy us
much, as the info name space is flat, and it complicates makefiles.
Overhaul info.pl:
- It now wants to run in the root of the build tree.
- Information on source files and subjects is now stored in makefiles,
thus info.pl no longer picks up random junk from the file system.
- Clean up Perl anachronisms, in particular use subroutine arguments and
results rather than global variables where convenient.
- Change format of diagnostics to the common format used by GNU tools,
so that Emacs and the like can parse it.
- Catch missing .SA.
- When creating a new subject file, cowardly refuse to overwrite an
existing file.
- Subject files contain topics sorted by chapter, then by name. The
order of chapters used to depend on how Perl sorts hash keys. Fix
it.
