Fix sanei_tcp_read(). Revert some getopt logic.

* 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.
