This feature supports the Intel Vtune profiling support for JITted
JavaScript on IA32 / X64 / X32 platform. The advantage of this profiling
is that the user / developer of NodeJS application can get the detailed
profiling information for every line of the JavaScript source code.
This information will be very useful for the owner to optimize their
applications.
This feature is a compile-time option. For windows platform, the user
needs to pass the following parameter to vcbuild.bat: "enable-vtune"
For other OS, the user needs to pass the following parameter to
./configure command: "--enable-vtune-profiling"

The tick processor is used to provide readable profiling information
from isolate tick logs (produced by a call to node -prof).
This patch installs the file at $PREFIX/share/doc/node/tick-processor.

Versions of Node.js after v0.12 have relocated byte-swapping away from
the StringBytes::Encode function, thereby causing a nan test (which
accesses this function directly) to fail on big-endian machines.
This change re-introduces byte swapping in StringBytes::Encode,
done via a call to a function in util-inl. Another change in
NodeBuffer::StringSlice was necessary to avoid double byte swapping
in big-endian function calls to StringSlice.

Because Node modules are wrapped, errors on the first line
of a file leak the wrapper to the user and report the wrong
column number. This commit adds a line break to the module
wrapper so that the first line is treated the same as all
other lines. To compensate for the additional line, a line
offset of -1 is also applied to errors.

The original test was only testing some of the headers that shouldn't be
concatenated as per lib/_http_incoming.js, so now the full list is
there.
'content-length` gives a parse error if you set it to a string, so the
test for that header uses numbers.

In debugger, the usage of `repl` very ugly. I'd like there is a `p`
like gdb. So the `exec` is coming.
Usage:
```
$ ./iojs debug ~/git/node_research/server.js
< Debugger listening on port 5858
connecting to 127.0.0.1:5858 ... ok
break in /Users/jacksontian/git/node_research/server.js:1
> 1 var http = require('http');
2
3 http.createServer(function (req, res) {
debug> exec process.title
/Users/jacksontian/git/io.js/out/Release/iojs
debug>
```
And the `repl`:
```
debug> repl
Press Ctrl + C to leave debug repl
> process.title
'/Users/jacksontian/git/io.js/out/Release/iojs'
debug>
(^C again to quit)
```
The enter and leave debug repl is superfluous.

deps/openssl/openssl
deps: copy all openssl header files to include dir
All symlink files in `deps/openssl/openssl/include/openssl/`
are removed and replaced with real header files to avoid
issues on Windows. Two files of opensslconf.h in crypto and
include dir are replaced to refer config/opensslconf.h.
deps: fix openssl assembly error on ia32 win32
`x86masm.pl` was mistakenly using .486 instruction set, why `cpuid` (and
perhaps others) are requiring .686 .
deps: fix asm build error of openssl in x86_win32

deps: add -no_rand_screen to openssl s_client
In openssl s_client on Windows, RAND_screen() is invoked to initialize
random state but it takes several seconds in each connection.
This added -no_rand_screen to openssl s_client on Windows to skip
RAND_screen() and gets a better performance in the unit test of
test-tls-server-verify.
Do not enable this except to use in the unit test.
deps: update openssl config files

deps: update openssl asm and asm_obsolete files
