[RFC 00/17] Merge event loop implementations

I rebased this series recently.

I wasn't sure what the status really was.  I thought this at the time:

Tom> So, my view is that the current patch series is probably roughly ok.

... meaning that gdb_fildes_t could be removed and replaced with plain
"int", and nothing else would have to change.

I can re-test the series on Windows.  The updates due to rebasing were
all mechanical, though, stuff like making sure the files were moved into
the now-correct directories.

I thought maybe we could use gdb_select in gdbsupport, but now I see it
reaches into the serial code, so maybe that isn't so easy after all.

Let me know what you think.
