* sanei/sanie_tcp.c, backend/epson2_net.c: Update
sanei_tcp_read() to better simulate old behavior of MSG_WAITALL.
recv() tends to return MTU sized chunks of data without that option. And at
least cygwin doesn't support MSG_WAITALL. Re-enable epson2 using that
function for big recieves.
* libgetopt.c, libgetopt1.c:
Revert some logic meant to be used only when we were always compiling
interal getopt() functions. Fix header filename.
sanei/sanei_tcp.c, sanie/sanei_udp.c: Improve portablity by
removing usage of MSG_WAITALL since not all platforms support
that (cygwin). Default is to be blocking anyways. Changed
usage of MSG_NOTWAIT to use fcntl() function as needed as well.
* configure.in, lib/Makefile.in, lib/strcasestr.c: Add internal
strcasestr() for platforms missing it (cygwin).
* pixma_common.c: My source match header prototype for picky
compilers (cygwin).
* backend/umax_pp_mid.c: Allow BACKEND_NAME to be filename
yet debug to be SANE_DEBUG_UMAX_PP to match man page.
in multiple files, added networking
support, added FS G extended handshaking mode,
make proper use of extended commands when possible
* sanei/sanei_tcp.c: read now wait until all
the requested data is available.
