On localized, non-English versions of windows, it is
common to have two active charsets -- for console applications
and for GUI applications, together with localized error messages
returned by windows. But two charsets are rarely compatible,
so sending the same byte sequence to console and to windows
event log makes one or another to be unreadable. So at least
include the error number, this way it will be possible to
lookup the actual error test using external ways.

This feature is not necessary anymore since we have tools like valgrind today
that can catch stack overflow errors before they make a backtrace in gdb
impossible.
- Update year numbers in copyright headers.
- Add copyright information for Michael Tokarev and Florian Forster to the
copyright headers of files to which they have contributed significantly.
- Mention Michael and Florian in AUTHORS.
- Mention that tinc is GPLv3 or later if compiled with the --enable-tunemu
flag.
This allows us to use getaddrinfo(), getnameinfo() and related functions, which
allow tinc to make connections over existing IPv6 networks. These functions are
not available on Windows 2000 however. By default, support is enabled, but when
compiling for Windows 2000 the configure switch --with-windows2000 should be
used.
Since getaddrinfo() et al. are not functions but macros on Windows, we have to
use AC_CHECK_DECLS() instead of AC_CHECK_FUNCS() in configure.in.
These functions wrap asprintf() and vasprintf(), and check the return value. If
the function failed, tinc will exit with an error message, similar to xmalloc()
and friends.
If we didn't read any number from a pid file, we'll return
an unitialized variable to the caller, and it will treat
that garbage as a pid of a process (possible to kill).
Fix that.
