Move stuff to untangle the ugly cyclic dependencies between the
archives built for selected subdirectories of src/lib/:
* Move common/io.c to empthread/ because it requires empthread stuff
* Move parts of subs/nstr.c to common/nstreval.c to satisfy
common/ef_verify.o
* Move getstarg.c getstring.c onearg.c from gen/ to subs/ because they
require stuff from there
* Move bridgefall.c check.c damage.c empobj.c journal.c maps.c
sectdamage.c from common/ to subs/ because they require stuff from
there
* Move cnumb.c from subs/ to common/ to satisfy common/type.o
* Move log.c fsize.c from common/ to gen/ because they really belong
there
* Move emp_config.c mapdist.c from gen/ to common/ because they really
belong there, and require stuff from libglobal.a
Also package as/ as libas.a to satisfy common/path.o.

anyway.
other. Ensure headers in include/ can be included in any order
(except for econfig-spec.h, which is special). New header types.h to
help avoid inclusion cycles. Sort include directives. Remove some
superflous includes.
check both EAGAIN and EWOULDBLOCK. These are distinct on some
systems, e.g. HP-UX.
(io_output) [hpux]: Used to treat all errors as EWOULDBLOCK. This
looks like a inept attempt to `fix' the above. Remove.
in the VC7 version of winsock2.h. In version VC7, the #pragma
pack(push) and pack(pop) have an #ifdef !WIN32 add to them. However,
if WIN32 is not defined at the beginning, the push is done but by the
time the pop is reach something else has set WIN32 define so the pop
is not done, and it changes the default pack from /Zp2 to /Zp4, which
makes the data structures incompatible between objects with winsock2.h
and without winsock2.h. By adding the WIN32 both the push and pop are
not done.
thread entrypoints:
(lwpSelect, shutdown_sequence): Parameters didn't match thread entry
point prototype.
(lwpEntryPoint): Arguments didn't match thread entry point prototype.
Change linkage of functions without prototype declaration to static
where possible.
Remove some superflous declarations, replace others by suitable
includes.
(io_select, io_flush, io_iopfromfd): Unused, remove.
(io_open): Allow more than one open for the same file descriptor.
The check is the last remaining use of io_list[], and it's
unimportant.
(io_list, niop, io_init): io_list[] no longer serves any purpose,
remove. Sparse allocation of file descriptors (deplorable misfeature
of Winsock, at least some versions) is no longer a problem.
(getfdtablesize): Unused, remove. Was broken for Windows anyway.
io_list[] indexing.
(niop, io_init): Store length of io_list[] in new niop.
(player_accept): Checking the socket file descriptor here is now
redundant. Remove.
io_puts, iom_create, iom_getmask, iom_set, iom_clear, iom_zero):
Portability bug: io_select() passed bit_fdmask to select(). This
breaks the fd_set abstraction, and works only with the traditional
Unix implementation of fd_set. Use fd_set and its operations instead.
Remove unused source files. Note: the offending code is currently
unsued. But it's a time bomb, and fixing it also replaces a bunch of
code by standard library services.
