If a Read or Write blocks for too long, time out the operation. Otherwise, some
kinds of test failures result in hangs, which prevent the test harness from
progressing. (Notably, OpenSSL currently has a lot of those failure modes and
upstream expressed interest in being able to run the tests to completion.)
Go's APIs want you to send an absolute timeout, to avoid problems when a Read
is split into lots of little Reads. But we actively want the timer to reset in
that case, so this needs a trivial adapter.
The default timeout is set at 15 seconds for now. If this becomes a problem, we
can extend it or build a more robust deadlock detector given an out-of-band
channel (shim tells runner when it's waiting on data, abort if we're also
waiting on data at the same time). But I don't think we'll need that
complexity. 15 seconds appears fine for both valgrind and running tests on a
Nexus 4.

On Windows, file descriptors are provided by the C runtime, while sockets must

Also add a TODO to resolve the SOCKET vs int thing. This code assumes that
Windows HANDLEs only use the bottom 32 bits of precision. (Which is currently
true and probably will continue to be true for the foreseeable future[*], but
it'd be nice to do this right.)

C is still kind of unsure about the whole two's complement thing and leaves
left-shifting of negative numbers undefined. Sadly, some sanitizers believe in
teaching the controversy and complain when code relies on the theory of two's
complement.
Shushing these sanitizers in this case is easier than fighting with build
configuration, so replace the shifts with masks. (This is equivalent as the
left-shift was of a value right-shifted by the same amount. Instead, we store
the unshifted value in carry0, etc., and mask off the bottom bits.) A few other
places get casts to unsigned types which, by some miracle, C compilers are
forbidden from miscompiling.
