util.h doesn't use REF, serialize.h does, creating a dependency of
serialize.h on util.h, but util.h already depends on serialize.h. To
resolve this circular dependency the function 'REF' has now been moved
closer to one of its two points of use.

In the assert()s take advantage of the fact that string constants
("string") are effectively of type 'const char []', which when used in
an expression yield a non-NULL pointer.
An assertion that should always fail can thus be formulated as:
assert(!"fail);
An assertion where a text message should be added to the expression can
be written as such:
assert("message" && expression);

Use non-blocking connects, and a select() call to wait a predefined
time (5s by default, but configurable with -timeout) for either
success or failure. This allows much more connections to be tried
per time unit.
Based on a patch by phantomcircuit.
