And fix last failing tests

This reverts commit 53716eb0.

socket.authorizationError should always be string. Also make sni test
pass.

It's useful for passing some additional options of request object to the
underlying API

When there is an error that is thrown in a nextTick function, which is
then handled by a domain or other process.on('uncaughtException')
handler, if the error handler *also* adds a nextTick and triggers
multiple MakeCallback events (ie, by doing some I/O), then it would
skip over the tickDepth check, resulting in an infinite spin.

Solution: Check the tickDepth at the start of the tick processing, and
preserve it when we are cleaning up in the error case or exiting early
in the re-entry case.

In order to make sure that tick callbacks are *eventually* handled, any
callback triggered by the underlying spinner in libuv will be processed
as if starting from a tick depth of 0.

I disabled the -ffunction-sections and -fdata-sections switches in 202df30a
because they're horribly buggy with some gcc/binutils combos.

However, it turns out that the dtrace/ustack post-processing tool requires
that V8 is compiled with said switches and was broken because of it.

This commit turns them on again on SunOS systems. Let's hope for the best.

The system linker on SunOS doesn't understand --export-dynamic.

Unconditionally compile V8 with -fno-strict-aliasing on all platforms.

gcc 4.5.2 on sunos generates bad code when -fstrict-aliasing is enabled, which
undoubtedly means that there are more buggy versions of gcc out there.

-fstrict-aliasing does not give a significant performance boost so let's just
disable it.

Fixes #3736.

Explicitly cast double to int64_t, it was making add-ons that compile with
`-Wall -Wextra -Werror` fail to build.

Don't use fully variadic macros, gcc in uber-strict mode rejects them.

genv8constants was much slower than necessary due to lack of pipe buffering.

This is rewrite of #3701 and #3603 before.

This patch introduce `util.inspect.styles`
and `util.inspect.colors` objects, which enables customization
of color sequences.
