Upgrade the bundled V8 and update code in src/ and lib/ to the new API.
Notable backwards incompatible changes are the removal of the smalloc
module and dropped support for CESU-8 decoding. CESU-8 support can be
brought back if necessary by doing UTF-8 decoding ourselves.
This commit includes https://codereview.chromium.org/1192973004 to fix
a build error on python 2.6 systems. The original commit log follows:
Use optparse in js2c.py for python compatibility
Without this change, V8 won't build on RHEL/CentOS 6 because the
distro python is too old to know about the argparse module.

With V8 4.4 removing the external array data API currently used by
Buffer, the new implementation uses the Uint8Array to back Buffer.
Buffers now have a maximum size of Smi::kMaxLength, as defined by V8.
Which is ~2 GB on 64 bit and ~1 GB on 32 bit.
The flag --use-old-buffer allows using the old Buffer implementation.
This flag will be removed once V8 4.4 has landed.
The two JS Buffer implementations have been split into two files for
simplicity.
Use getter to return expected .parent/.offset values for backwards
compatibility.

These two lines exist because of a screw up on my part while combining
MakeCallback() and MakeDomainCallback().
The reason it never broke core tests is because any paths it would have
broken were rerouted to AsyncWrap::MakeCallback(). The only case that
node::MakeCallback() handles anymore is setImmediate().

Re-add the wrapper class id to AsyncWrap instances so they can be
tracked directly in a heapdump.
Previously the class id was given without setting the heap dump wrapper
class info provider. Causing a segfault when a heapdump was taken. This
has been added, and the label_ set to the given provider name so each
instance can be identified.
The id will not be set of the passed object has no internal field count.
As the class pointer cannot be retrieved from the object.
In order to properly report the allocated size of each class, the new
pure virtual method self_size() has been introduces.

Use the --trace-sync-io flag to print a stack trace whenever a sync
method is used after the first tick, excluding during the process exit
event. (e.g. fs.readFileSync()) It does not track if the warning has
occurred at a specific location in the past and so will print the
warning every time.
Reason for not printing during the first tick of the appication is so
all necessary resources can be required. Also by excluding synchronous
calls during exit is necessary in case any data needs to be logged out
by the application before it shuts down.

Drop the homegrown thread pool that was introduced in commit 50839a0
("v8_platform: provide default v8::Platform impl") and use one from
V8's libplatform library. Performance is comparable and it removes
a few hundred lines of code.
The calls to v8::platform::PumpMessageLoop() are currently no-ops
because V8 does not (yet?) use v8::Platform::CallOnForegroundThread().
Packagers that link against a shared libv8 now also need to make
libv8_platform available.

This patch adds a command line option (-r/--require) that allows one

-r/--require can be used to preload modules on node startup. The option

This patch allows 'vendors' (such a cloud host) to inject functionality

require from the user's application. This can be useful to load vendor

If run with --abort-on-uncaught-exception, V8 will abort the process
whenever it does not see a JS-installed CatchClause in the stack. C++
TryCatch clauses are ignored. Domains work by setting a FatalException
handler which is ignored when running in abort mode.
This patch modifies MakeCallback to call its target function through a
JS function that installs a CatchClause and manually calls _fatalException
on error, if the process is both using domains and is in abort mode.

The benefits are quite substantial on systems where it is expensive to

common to see over 20% of wall clock time being spent on clock_gettime()
system calls.
