The `__attribute__((deprecated("warning")))` macro didn't exist until
gcc 4.5 and clang 2.9.
While io.js does not build with compilers that old, add-ons do. Let's
make src/node.h compatible with such compilers, it's a public header.

The NODE_DEPRECATED macro was piggybacking on the V8_DEPRECATED macro
but that macro is silent unless V8_DEPRECATION_WARNINGS is defined,
something io.js doesn't do. Ergo, no deprecation notices were being

It's currently not really possible to compile native add-ons with
-fvisibility=hidden because that also hides the struct containing
the module definition.
The NODE_MODULE() and NODE_MODULE_DECL() macros are structured in
a way that makes it impossible to add a visibility attribute manually
so there is no escape hatch there.
That's why this commit adds an explicit visibility attribute to
the module definition. It doesn't help with node.js releases that
are already out there but at least it improves the situation going
forward.
The linker was optimizing the static variables that were supposed
to trigger module initialization.
I am making them non-static, and dllexport so that they don't get
optimized away.

fix#6920fix#1310
Make it possible to invoke MakeCallback() on a v8::Value but only for
the variant that takes a v8::Function as the thing to call.
The const char* and v8::String variants still require a v8::Object
because the function to call is looked up as a property on the receiver,
but that only works when the receiver is an object, not a primitive.
This matches how libuv handles the definition of ssize_t, by
typedef'ing intptr_t to ssize_t.
However, in the future we will use portable types from stddef.h
Built-in modules should be automatically registered, replacing the
static module list. Add-on modules should also be automatically
registered via DSO constructors. This improves flexibility in adding
built-in modules and is also a prerequisite to pure-C addon modules.
addon_register_func and its cousin addon_context_register_func are type
definitions, dllimport and dllexport are name mangling directives, i.e.
they're quite unrelated concepts. MinGW complains about mixing them
when cross-compiling native add-ons.

Fixes a 4 byte leak on handles closing. AKA The Walmart leak.
MakeCallback doesn't have a HandleScope. That means the callers scope
will retain ownership of created handles from MakeCallback and related.
There is by default a wrapping HandleScope before uv_run, if the caller
doesn't have a HandleScope on the stack the global will take ownership
which won't be reaped until the uv loop exits.
If a uv callback is fired, and there is no enclosing HandleScope in the
cb, you will appear to leak 4-bytes for every invocation. Take heed.

Turns out that we don't use node_object_wrap.h any more in core,
and, with v8 3.21, it's breaking our Windows build. Removing refs
to it everywhere (and adding node.h in one case where it was the
only way node.h was being included), we have restored the Windows
build.
This commit makes it possible to use multiple V8 execution contexts
within a single event loop. Put another way, handle and request wrap
objects now "remember" the context they belong to and switch back to
that context when the time comes to call into JS land.
This could have been done in a quick and hacky way by calling
v8::Object::GetCreationContext() on the wrap object right before
making a callback but that leaves a fairly wide margin for bugs.
Instead, we make the context explicit through a new Environment class
that encapsulates everything (or almost everything) that belongs to
the context. Variables that used to be a static or a global are now
members of the aforementioned class. An additional benefit is that
this approach should make it relatively straightforward to add full
isolate support in due course.
There is no JavaScript API yet but that will be added in the near
future.

* Exit with an error message when the option is not a node or V8 option.
* Remove the option_end_index global. Needs to happen anyway for
the multi-context work, might as well land it in master now.
* Add a smidgen of const-correctness.
* Pay off a few years of accrued technical debt.
* Change calls to String::New() and String::NewSymbol() to their
respective one-byte, two-byte and UTF-8 counterparts.
* Add a FIXED_ONE_BYTE_STRING macro that takes a string literal and
turns it into a v8::Local<v8::String>.
* Add helper functions that make v8::String::NewFromOneByte() easier to
work with. Said function expects a `const uint8_t*` but almost every
call site deals with `const char*` or `const unsigned char*`. Helps
us avoid doing reinterpret_casts all over the place.
* Code that handles file system paths keeps using UTF-8 for backwards
compatibility reasons. At least now the use of UTF-8 is explicit.
* Remove v8::String::NewSymbol() entirely. Almost all call sites were
effectively minor de-optimizations. If you create a string only once,
there is no point in making it a symbol. If you are create the same
string repeatedly, it should probably be cached in a persistent
handle.
Libuv now returns errors directly. Make everything in src/ and lib/
follow suit.
The changes to lib/ are not strictly necessary but they remove the need
for the abominations that are process._errno and node::SetErrno().
This is a big commit that touches just about every file in the src/
directory. The V8 API has changed in significant ways. The most
important changes are:
* Binding functions take a const v8::FunctionCallbackInfo<T>& argument
rather than a const v8::Arguments& argument.
* Binding functions return void rather than v8::Handle<v8::Value>. The
return value is returned with the args.GetReturnValue().Set() family
of functions.
* v8::Persistent<T> no longer derives from v8::Handle<T> and no longer
allows you to directly dereference the object that the persistent
handle points to. This means that the common pattern of caching
oft-used JS values in a persistent handle no longer quite works,
you first need to reconstruct a v8::Local<T> from the persistent
handle with the Local<T>::New(isolate, persistent) factory method.
A handful of (internal) convenience classes and functions have been
added to make dealing with the new API a little easier.
The most visible one is node::Cached<T>, which wraps a v8::Persistent<T>
with some template sugar. It can hold arbitrary types but so far it's
exclusively used for v8::Strings (which was by far the most commonly
cached handle type.)
Most TryCatch blocks have SetVerbose flag on, this tells V8 to report
uncaught exceptions to debugger.
FatalException handler is called from V8 Message listener instead from
the place where TryCatch was used. Otherwise uncaught exceptions are
logged twice.
See comment in `deps/v8/include/v8.h` for explanation of SetVerbose
flag:
> By default, exceptions that are caught by an external exception
> handler are not reported. Call SetVerbose with true on an
> external exception handler to have exceptions caught by the
> handler reported as if they were not caught.
The flag is used by `Isolate::ShouldReportException()`, which is called
by `Isolate::DoThrow()` to decide whether an exception is considered
uncaught.
Commit 0bba5902 accidentally (or maybe erroneously) added node_isolate
to src/node.h and src/node_object_wrap.h.
Undo that, said variable is not for public consumption. Add-on authors
should use v8::Isolate::GetCurrent() instead.
I missed that while reviewing. Mea culpa.
Fixes#5639.
