This patch adds the openpty() and forkpty() library calls to posixmodule.c,
when they are available on the target
system. (glibc-2.1-based Linux systems, FreeBSD and BSDI at least, probably
the other BSD-based systems as well.)

Lib/pty.py is also rewritten to use openpty when available, but falls
back to the old SGI method or the "manual" BSD open-a-pty
code. Openpty() is necessary to use the Unix98 ptys under Linux 2.2,
or when using non-standard tty names under (at least) BSDI, which is
why I needed it, myself ;-) forkpty() is included for symmetry.

MSVC project file for the new module ucnhash. This may have to
be added to pcbuild.dsw with an dependancy on python16.

New ucnhash module by Bill Tutt. This module contains the hash
table needed to map Unicode character names to Unicode ordinals
and is loaded on-the-fly by the standard unicode-escape codec.

Exports the C API of the new ucnhash module.

methods (but not 'link_executable()', hmmm).  Currently only used by
BCPPCompiler; it's a dummy parameter for UnixCCompiler and MSVCCompiler.

Also added 'bcpp' to compiler table used by 'new_compiler()'.

Two major points:
  * lots of overlap with MSVCCompiler; the common code really should be
    factored out into a base class, say WindowsCCompiler
  * it doesn't work: weird problem spawning the linker (see comment for
    details)

Various formatting tweaks, typo fixes in comments.

Define a STRICT_SYSV_CURSES macro on SGI, Sun, and Tru64, to mark systems
that don't support some features.

getmouse(), ungetmouse(), and window.enclose().  wmouse_trafo() seems
of marginal importance at the moment.

Ditched my old code that fixed relative paths in the Makefile -- didn't work,
  doomed to failure, etc.

the 'implib_dir' attribute is back (only on NT, of course).

Also supposedly made some change to where .lib files wind up under MSVC++,
  but I don't understand how to code is doing what Thomas says it's
  doing.

Added 'check_lib()', which provides a subset of the functionality of
  'check_func()' with a simpler interface and implementation.

and I lack the time to track down the cause.

parsing the sample data once with 8-bit strings and once with Unicode.

This version still includes #ifdef hackery to compile with 1.5.2.
