Add a 'minmax' module with typesafe macros to compute minimum, maximum and
clamping.  Inspired by the versions used in the Linux kernel, but using
a different implementation based on __builtin_types_compatible_p() and the
build_assert module.

If one connect failed, we'd return the other one without
waiting for the connect to complete.  This resulted in
read() returning 0, which was really weird.

The downside: the poll doesn't seem to time out when the
connect times out (Linux 3.13 x86-64).

Bitmap words (e.g. resulting from BITMAP_{N,HEAD}WORDS) are of
unsigned type.

Use "unsigned int" to iterate over bitmap words to avoid comparisons
between signed and unsigned expressions. GCC otherwise warns about
these when -Wsign-compare is enabled.

Simpler reimplementation of SS's patch; just plumb file and line through
inline functions in header.  We add a new check, which actually tests
these, and fix _info which missed ccan/check_type as a dependency.

This one is a bit more complex, but allows either tab or space.
