deps: add gyp, header and Makefile for openssl110

This commit has a new binding scheme in builing OpenSSL-1.1.0 library
with Node. OpenSSL-1.1.0 uses a new build system with perl for various
supported platforms. See `Configurations/README` and
`Configurations/README.design` in the OpenSSL source for details.

In order to build OpenSSL library without perl in the build of Node
for various supported platforms, platform dependent files (e.g. asm
and header files ) are pre-generated and stored into the `config/arch`
directory.

- Makefile and generate_gypi.pl
Makefile has supported platform list and generates and copies platform
dependent files (e.g. asm files) into arch directory with
generate_gypi.pl. Platform dependent gypi files also created obtaining
build information from `configdata.pm` that is generated with
`Configure` in the OpenSSL build system.

For Windows, `Configure` generates makefile that is only available to
nmake command.  Since nmake is not supported in Linux,
`Makefile_VC-WIN32` and `Makefile_VC-WIN64A` are made created by hand
for the use of GNU make. If make rules or targets are changed in the
version up of OpenSSL, they should be also updated.

The following files are used in upgrading openssl-1.1.0.

- gyp and gypi files
openssl.gyp has two targets of openssl and openssl-cli referred from
node.gyp. They includes asm and no_asm gypi files with arch dependent
gypi according to its build options and platforms . The gyp data which
is common with asm and no_asm are stored in openssl_common.gypi.

- header files
bn_conf.h, dso_conf.h and opensslconf.h are platform dependent in the
OpenSSL sources. They are replaced with *.h.tmpl files to include the
file in the `../../../config/` and referred to each arch files that
depends on asm and no-asm option.
