This commit improves parse() performance by ~20-200% with the various
querystring-parse benchmarks.
Some optimization strategies used in this commit include:
* Combining multiple searches (for '&', '=', and '+') on the same
string into a single loop
* Avoiding string.split()
* Minimizing creation of temporary strings
* Avoiding string decoding if no encoded bytes were found and the
default string decoder is being used

This change adds ESLint rules that meet two criteria:
* recommended by ESLint
* require no code changes
These rules are:
* `no-func-assign`: Disallow overwriting a function that was written
as a function declaration.
* `no-negated-in-lhs`: Disallow negated left operand of `in` operator.
It prevents `if(!a in b)` when `if(!(a in b))` is intended.
* `no-obj-calls`: Disallow global object function calls. It prevents
errors like `JSON()` and `Math()`.
to exercise the code in tests or whatever, it can sneak in.
* `use-isnan`: Prevents errors like `if (foo == NaN)`
* `no-octal`: Disallows confusing constructs like `var num = 071;`
* `no-delete-var`: Delete works on properties, not variables. Disallows
`delete foo`.

After attempting to use ReThrow() and Reset() there were cases where
firing the domain's error handlers was not happening. Or in some cases
reentering MakeCallback would still cause the domain enter callback to
abort (because the error had not been Reset yet).
In order for the script to properly stop execution when a subsequent
call to MakeCallback throws it must not be located within a TryCatch.

Add a scope that will allow MakeCallback to know whether or not it's

Implementations of error handling between node::MakeCallback() and
AsyncWrap::MakeCallback() do not return at the same point. Make both
executions work the same by moving the early return if there's a caught
exception just after the AsyncWrap post callback. Since the domain's
call stack is cleared on a caught exception there is no reason to call
its exit() callback.
Remove the SetVerbose() statement in the AsyncWrap pre/post callback
calls since it does not affect the callback call.

Prior to this change, the NodeBIO objects used to wrap fixed data had
`num` equal to -1. This caused them to return -1 and set the retry flags
when they ran out of data. Since the data is fixed, that's incorrect.
Instead they should return zero to signal EOF.
This change adds a new, static function, NodeBIO::NewFixed to create a
BIO that wraps fixed data and which returns zero when exhausted.
The practical impact of this is limited since most (all?) the parsing
functions that these BIOs get passed to consider any return value less
than one to be EOF and ignore the retry flags anyway.

Ported by exinfinitum from a PR by jasnell:
see https://github.com/nodejs/node-v0.x-archive/pull/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.

A multibyte strings will simply be copied into the Buffer until the
number of bytes run out. Meaning partial strings can be left behind:

The `--security-revert={cvenum}` command line flag is a special purpose
flag to be used only in stable or LTS branches when a breaking change
is required to address a security vulnerability. Whenever a vulnerability
requires a breaking change, and a CVE has been assigned, the flag can
be used to force Node to revert to the insecure behavior that was
implemented before the fix was applied.
Note that this flag is intended to be used only as a last resort in the
case a security update breaks existing code. When used, a security
warning will be printed to stderr when Node launches.
The `--security-revert={cvenum}` flag takes a single CVE number as an
argument. Multiple instances of the `--security-revert={cvenum}` flag
can be used on the command line to revert multiple changes.
Whenever a new `--security-revert={cvenum}` is enabled, it should be
documented in the release notes and in the API docs.
Master and the first release of a new major (e.g. v6.0) should not have
any reverts available.
Every time a new `--security-revert={cvenum}` is added, there should be
a semver-minor bump in the stable and LTS branch.
