Make `HTTPParser` an instance of `AsyncWrap` and make it use
`MakeCallback`. This means that async wrap hooks will be called on
consumed TCP sockets as well as on non-consumed ones.

Additional uses of `AsyncCallbackScope` are necessary to prevent
improper state from progressing that triggers failure in the
test-http-pipeline-flood.js test. Optimally this wouldn't be necessary,
but for the time being it's the most sure way to allow operations to
proceed as they have.

In AsyncWrap::MakeCallback always return empty handle if there is an
error. In the future this should change to return a v8::MaybeLocal, but
that major change will have to wait for v6.x, and these changes are
meant to be backported to v4.x.

The HTTParser call to AsyncWrap::MakeCallback failed because it expected
a thrown call to return an empty handle.

In node::MakeCallback return an empty handle if the call is
in_makecallback(), otherwise return v8::Undefined() as usual to preserve
backwards compatibility.

Now that HTTPParser uses MakeCallback it is unnecessary to manually
process the nextTickQueue.

The KickNextTick function is now no longer needed so code has moved back
to node::MakeCallback to simplify implementation.

Include minor cleanup moving Environment::tick_info() call below the
early return to save an operation.

Rather than abort if the init/pre/post/final/destroy callbacks throw,
force the exception to propagate and not be made catchable. This way
the application is still not allowed to proceed but also allowed the
location of the failure to print before exiting. Though the stack itself
may not be of much use since all callbacks except init are called from
the bottom of the call stack.

On UNIX platforms, the debugger doesn't reliably kill the inferior when

This is a hack to get the continuous integration back to green, it
doesn't address the underlying issue, which is that the debugger
shouldn't leave stray processes behind.

Changes to Node core in order to allow compilation for linuxOne.

The ../archs/linux32-s390x/opensslconf.h and
../archs/linux64-s390x/opensslconf.h were automatically
generated by running make linux-ppc linux-ppc64 in the
deps/openssl/config directory as per our standard
practice

After these changes we still need a version of v8
which supports linuxOne but that will be coming soon
in the 5.1 version of v8.  Until then with these changes
we'll be able to create a hybrid build which pulls in
v8 from the http://github/andrewlow repo.

Ported by exinfinitum from a PR by jasnell:
see nodejs/node-v0.x-archive#14185

Allows the running of v8 tests on node's packaged v8 source code.

Note that the limited win32 support added by jasnell has NOT been ported,
and so these tests are currently UNIX ONLY.

Note that gclient depot tools
(see https://commondatastorage.googleapis.com/
chrome-infra-docs/flat/depot_tools/docs/html/
depot_tools_tutorial.html#_setting_up) and subversion are required
to run tests.

To perform tests, run the following commands:

make v8 DESTCPU=(ARCH)
make test-v8 DESTCPU=(ARCH)

where (ARCH) is your CPU architecture, e.g. x64, ia32.
DESTCPU MUST be specified for this to work properly.

Can also do tests on debug build by using "make test-v8 DESTCPU=(ARCH)
BUILDTYPE=Debug", or perform intl or benchmark tests via make
test-v8-intl or test-v8-benchmarks respectively.

Note that by default, quickcheck and TAP output are disabled, and i18n
is enabled. To activate these options, use options"QUICKCHECK=True" and
"ENABLE_V8_TAP=True" respectively.

Use "DISABLE_V8_I18N" to disable i18n.

Use V8_BUILD_OPTIONS to allow custom user-defined flags to be
appended onto "make v8".

Any tests performed after changes to the packaged v8 file will require
recompiling of v8, which can be done using "make v8 DESTCPU=(ARCH)".

Finally, two additional files necessary for one of the v8 tests have
been added to the v8 folder.

Don't cache the exported values of fully uninitialized builtins.
This works by adding an additional `loading` flag that is only
active during initial loading of an internal module and checking
that either the module is fully loaded or is in that state before
using its cached value.

This has the effect that builtins modules which could not be loaded
(e.g. because compilation failed due to missing stack space) can be
loaded at a later point.

This is part 2/2 of the fixes needed for v8:4871. This fix never landed
upstream because the bug is not present in active V8 version. The patch
is available from the upstream v8 bug however.

The segfault occurs at the intersection of the following three
conditions that are dependent on the allocation pattern of an
application: A pretenured (1) allocation site has to be optimized into
a merged allocation by the allocation folding optimization (2) and
there needs to be overflow of the store buffer (3).

This patch disables the allocation folding optimization for pretenured
allocations. This may have some, hopefully negligible, performance
impact on real world applications.
