buffer: proper API export for Windows

So that Windows users can properly include smalloc and node_buffer,
NODE_EXTERN was added to the headers that export this functionality.
crypto: change assertion to condition in bio

Read head can be the same as write head, even if there's some data to
read.
buffer: write strings directly from call

Buffer(<String>) used to pass the string to js where it would then be
passed back to cpp for processing. Now only the buffer object
instantiation is done in js and the string is processed in cpp.

Also added a Buffer api that also accepts the encoding.
punycode: update to v1.2.3
buffer: fix gcc 4.2 build breakage

gcc 4.2 on OS X gets confused about the call to node::Buffer::Data().
Fully qualify the function name to help it along.

Fixes the following build error:

    ../../deps/v8/include/v8.h: In function ‘char*
    node::Buffer::Data(v8::Handle<v8::Value>)’:
    ../../deps/v8/include/v8.h:900: error: ‘class v8::Data’
    is not a function,
    ../../src/node_buffer.h:38: error:
    conflict with ‘char* node::Buffer::Data(v8::Handle<v8::Object>)’
    ../../src/node_buffer.cc:94: error:
    in call to ‘Data’

child_process: emit 'disconnect' asynchronously

Deferring I/O-triggered events to the next event loop tick is not just
a good idea, IT'S THE LAW!

crypto: do not move half-filled write head

Might cause write head running over read head, when there were no
allocation and `Commit()` was called. Source of at least one test
failure on windows (`simple/test-https-drain.js`).
uv: Upgrade to v0.11.5
src: break on uncaught exception

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.

zlib: allow zero values for level and strategy
zlib: level can be negative
zlib: remove unused parameter
zlib: allow custom flush type for flush()
zlib: allow changing of level and strategy
test: fix tls-hello-parser-failure on smartos

Assert that when the client closes it has seen an error, this prevents
the test from timing out.

Also queue a second write in the case that we were able to send the
buffer before the other side closed the connection.
