It might be non-blocking, but it also might be blocking.
Cannot take the chance, as Accept might block indefinitely
and make it impossible to acquire ForkLock exclusively
(during fork+exec).

This is necessary for systems that use select as the pollster,
such as Solaris (supported by gccgo).  It corresponds to the
bool returned by AddFD.  In general it's not clearly defined
what happens when a descriptor used in a select is closed, and
different systems behave differently.  Waking up the select
will cause the right thing to happen: the closed descriptor
will be dropped from the next iteration.

This CL is the first of a handful of CLs which will provide
the implementation of cookiejar. It contains several helper
functions and the skeleton of Cookies and SetCookies.

Proper host name handling requires the ToASCII transformation
from package idna which currently lives in the go.net
subrepo. This CL thus contains just a TODO for this issue.

Closing the inotify file descriptor can take over a second
when running on Ubuntu Precise in an NFS directory, leading to
the test error in issue 3132.  Closing the event channel first
lets a client that does not care about the error channel move
on.

Fixes #3132.

Plan 9 compilers insist this but as we don't have Plan 9
builders, we'd better let gcc check the prototypes.

The dashboard is currently failing to store results of new builds for some keys, notable the go.codereview sub repository. This is causing the builders to mark the entire triggering commit as failed.

If a Handle's Write to a ResponseWriter fails (e.g. via a
net.Conn WriteDeadline via WriteTimeout on the Server), the
Server was blocking forever waiting for reads on that
net.Conn, even after a Write failed.

Instead, once we see a Write fail, close the connection,
since it's then dead to us anyway.

Fixes #4741
