core: Use better error code when using select with a too high fd. 
* src/posix-io.c (_gpgme_io_select): Return EMFILE instead of EBADF.
--

Also EBADF seem more correct, EMFILE (Too man open files) gives
a clearer message to the user that there are somehow too many files
open.  The problem can be exhibited by running lots of threads,

We should eventually move to poll but that would be a large change and
so we better fix it with the planned migration of the I/O subsystem to
libgpgrt (currently known as libgpg-error).

617d3be629 Make sure a spawned process has all standard fds connected. 
* src/posix-io.c (_gpgme_io_spawn): dup /dev/null also to unsued
stdout.
--

Better be sure that stdout of a spawned process is connected to stdout
so that the process does not run into a write error if it writes to
stdout.  AFAICS we always use a connected stdout; thus this is only
for correctness.

987993a38d First take on changes to allow building with MSC for W32CE. 
Fixed regression in plain W32 build.

01ad3b7562 Changed the close notify implementaion to allow for more than 256 fds. 
We should write a test case for it, though.
