Re: [PATCH] compat: Add another rudimentary poll() emulation

Implement the subset of poll() semantics needed by git in terms of
select(), for use by the Interix port.  Inspired by commit 6ed807f
(Windows: A rudimentary poll() emulation, 2007-12-01).

A possible problem with this approach is that the maximum number of
file descriptors poll can handle limited by RLIMIT_NOFILE, whereas the
maximum number of file descriptors select can handle is limited by
FD_SETSIZE.

I don't think this is a big problem in reality, though - both values
seem to be pretty high in most implementations. And IIRC git-daemon is
the only one who needs more than 2, and it doesn't even check
RLIMIT_NOFILE.

If we decide to go this route, perhaps it'd make sense to change to
this code for Windows also? Our Windows-implementation of poll() has
some annoying limitations...
