Arguably a bug in talloc_realloc_array, which uses an unsigned for 
size, resulting in silent truncation and a memcpy into a too-small
buffer.

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).

A number of functions in bitmap.h take parameters which they don't modify

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.

This turns out to be the right sequence for pettycoin, which
wants to reap the child in the finish routine.  From that sample
size of 1, this is clearly the Right Thing!

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 was suggested by Luke, though his version insisted on using tab.
This one is a bit more complex, but allows either tab or space.
