assert: fix deepEqual regression

Change of Object.keys in ES6 breaks assert.deepEqual about primitive
values.

V8: https://code.google.com/p/v8/issues/detail?id=3443

Previously deepEqual depends on Object.key that throws an error for
a primitive value, but now Object.key does not throw.

doc: fix v8 doc headings so 'make doc' passes

Previously the code that builds the Table of Contents threw
an exception because of jump from an H1 heading directly to an H3
heading.

By changing the H3 heading to an H2, 'make doc' works again. This is
also consistent with other docs like console.markdown which use
H2 for method call documentation.

doc: document time() and timeEnd() relationship

`console.time()` and `console.timeEnd()` are very closely related. It's
useful to reference them both from each other.

Previously, console.time() did not mention that it needed to be paired
with a call to console.timeEnd() to be useful, and timeEnd() also failed
to mention that console.time() needed to be called first.

References in both directions have been added.

configure: remove compiler detection

The GCC version is no longer relevant since only 4.8 and newer are
supported. It's probably safe to assume clang on mac since V8 does
so too.

they are bound to a port / IP, return themselves. This

This commit adds a return statement to the dgram.Socket.close()
