To support Performance Counters on Windows, a number of
global `COUNTER_` methods were added that are undocumented
and really only intended to be used internally by Node.js.
Unfortunately, the perfctr support apparently hasn't even
worked for quite a while and no one has even complained.
This removes the perfctr support and replaces the global
functions with deprecated non-ops for now, with the intent
of removing those outright in the next major release cycle.

Escaping the `>` seems to resolve it.

Parse source code using acorn; extracting exports. When producing
documentation, match exports to headers. When a match is found, add a [src]
link.
This first commit handles simple exported classes and functions, and does so
without requiring any changes to the source code or markdown. Subsequent
commits will attempt to match more headers, and some of these changes are
likely to require changes to the source code and/or markdown.

Currently V8 only checks that the length of the source code is the
same as the code used to generate the hash, so we add an additional
check here:
1. During compile time, when generating node_javascript.cc and
node_code_cache.cc, we compute and include the hash of the
(unwrapped) JavaScript source in both.
2. At runtime, we check that the hash of the code being compiled
and the hash of the code used to generate the cache
(inside the wrapper) is the same.
This is based on the assumptions:
1. `internalBinding('code_cache_hash')` must be in sync with
`internalBinding('code_cache')` (same C++ file)
2. `internalBinding('natives_hash')` must be in sync with
`process.binding('natives')` (same C++ file)
3. If `internalBinding('natives_hash')` is in sync with
`internalBinding('natives_hash')`, then the (unwrapped)
code used to generate `internalBinding('code_cache')`
should be in sync with the (unwrapped) code in
`process.binding('natives')`
There will be, however, false positives if the wrapper used
to generate the cache is different from the one used at run time,
and the length of the wrapper somehow stays the same.
But that should be rare and can be eased once we make the
two bootstrappers cached and checked as well.

Currently, node.js depends on inspector_protocol indirectly through the
dependency on v8.
This is a dependency violation that will make it hard to roll V8 into
Node if V8 gets a newer inspector protocol version with incompatible
API. In fact, this surfaced on one of our bots when we tried to roll new
inspector_protocol into V8.
This patch adds inspector protocol and its required dependencies to node
deps:
- jinja2
- markupsafe

This patch adds a `make format-cpp` shortcut to the Makefile
that runs clang-format on the C++ diffs, and a
`make format-cpp-build` to install clang-format from
npm.
To format staged changes:
```
$ make format-cpp
```
To format HEAD~1...HEAD (latest commit):
```
$ CLANG_FORMAT_START=`git rev-parse HEAD~1` make format-cpp
```
To format diff between master and current branch head (master...HEAD):
```
$ CLANG_FORMAT_START=master make format-cpp
```
Most of the .clang-format file comes from running
```
$ clang-format --dump-config --style=Google
```
with clang-format built with llvm/trunk 328768 (npm version 1.2.3)
The clang-format version is fixed because different version of
clang-format may format the files differently.

This makes compiling v8_base much faster on Windows.
Sharding is disabled because the header would have to be precompiled
for each shard but is only once. The library is much smaller, so
sharding is unnecessary.
This is enabled by default, but disabled for CI and releases.

This patch makes it possible to generate the code cache
for the builtins directly from the original script object
(instead of compiling a new one) and after the script has
been run (via `NativeModule.require`). Before this patch
only the top level functions (the wrapped ones)
are included in the cache, after this patch the inner
functions in those modules will be included as well.
Also blacklists modules from dependencies like V8 and
node-inspect since we cannot guarantee that they are suitable
to be executed directly.

The LICENSE file has a few entries for things that no longer ship with
the code base. They are installed via npm instead. Remove them from the
license file.
Running the license builder on a fresh checkout will
result in errors until this change lands, since the necessary
information is not in the source tree until the `npm install` happens.
