versions of GNU libc, which can lead to nasty heap smashes (observed
with 2.2.93). Don't define RESOLVE_IPADDRESS for now, until we
readjust thread stack sizes.
(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_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.

lstats() to lsta() to uphold the convention that functions
implementing commands are named like the command or its four character
prefix. Closes#804587.
effect. Replace calls by struct assignment where possible. Replace
clear buffer, copy string to buffer by strncpy(). Use assignment to
clear when that's clearer. Replace overlapping copy through bounce
buffer by memmove(). Replace rest by standard memset() and memcpy().
Also use sizeof() instead of literal array sizes for robustness, and
instead of symbolic array sizes for clarity.
windows. For obvious reasons, such warnings ought to be fixed.
Making compilation abort is the sledgehammer method to force that.
It's a stupid method for us, as we develop on various platforms, and
don't test every single commit under Windows. It gratuitously breaks
programs that work fine. Leave them as warnings, and fix them on
sight.
