2015-03-19 io.js v1.6.0 Release

Notable Changes:

* node: a new -r or --require command-line option can be used to
  pre-load modules at start-up (Ali Ijaz Sheikh)
* querystring: parse() and stringify() are now faster (Brian White)
* http: the http.ClientRequest#flush() method has been deprecated and
  replaced with http.ClientRequest#flushHeaders() to match the same
  change now in Node.js v0.12 as per
  https://github.com/joyent/node/pull/9048 (Yosuke Furukawa)
* net: allow server.listen() to accept a String option for port, e.g.
  { port: "1234" }, to match the same option being accepted in
  net.connect() as of https://github.com/joyent/node/pull/9268 (Ben
  Noordhuis)
* tls: further work on the reported memory leak although there appears
  to be a minor leak remaining for the use-case in question, track
  progress at https://github.com/iojs/io.js/issues/1075.
* v8: backport a fix for an integer overflow when --max_old_space_size
  values above 4096 are used (Ben Noordhuis)
* platforms: the io.js CI system now reports passes on FreeBSD and
  SmartOS (_Solaris_).
* npm: upgrade npm to 2.7.1. See the npm CHANGELOG.md for details.

deps: upgrade to openssl-1.0.1m

All sources are just extracted from tarball into deps/openssl/openssl.

change all openssl/include/openssl/*.h to include resolved symbolic
links and openssl/crypto/opensslconf.h to refer config/opensslconf.h

sha256-x86_64.pl does not exist in the origin openssl distribution. It
was copied from sha512-x86_64.pl and both sha256/sha512 scripts were
modified so as to generates only one asm file specified as its key
hash length.

`x86masm.pl` was mistakenly using .486 instruction set, why `cpuid`
(and perhaps others) are requiring .686.

removed vpaesni-x86_64.asm in x64-win32-masm - it is no longer used.

an int64_t.  It works by accident when sizeof(size_t) == sizeof(int64_t)

v8::Isolate::AdjustAmountOfExternalAllocatedMemory() is the function I'm
talking about.  The goal of that call is to tell V8 that some memory has
been freed but due to that underflow, we were actually reporting that we

src: fix ucs-2 buffer encoding regression

StringBytes::Write() did a plain memcpy() when is_extern is true but
that's wrong when the source is a two-byte string and the destination
a one-byte or UTF-8 string.

The impact is limited to strings > 1,031,913 bytes because those are
normally the only strings that are externalized, although the use of
the 'externalize strings' extension (--expose_externalize_string) can
also trigger it.

This commit also cleans up the bytes versus characters confusion in
StringBytes::Write() because that was closely intertwined with the
UCS-2 encoding regression.  One wasn't fixable without the other.
