More mingw portability updates. Add check for winsock2.h for socket.h replancement. Also, use this check to add ws2_32 library. Also, switch all winsock.h references to winsock2.h. Add check for getuid and getpass; which are not on mingw. Add a syslog() replacement that is basically a print(). This is also used by vsyslog() replacement. Comment out parts of replacement sigprocmask.c on mingw. To support these configure.in changes, I need to rebuild all related files with autoconf 2.68 and libtool 2.4. Hand ported our sane-backend specific changes to newer ltmain.sh.

mingw32 compile fixes The following updates were made to all directories but backends. That still needs work. There are also still some pthread issues and syslog is missing. Windows doesn't support SIGHUP or SIGPIPE so make that optional. Only include socket header files when sys/socket.h is detected. Use winsock.h on windows. Only include syslog.h when vsyslog() was detect by configure. Skip FD_CLOEXEC when not supported by OS (not defined). Only include sys/ioctl.h on platforms that define it.
