Removing the third-party runtime dependencies

Removing zlib1g, libssl-dev, cryptopp, and expat.

Cryptography now uses public domain code in the source tree (source/detail/cryptography), zlib was replaced with miniz and added to the source tree (source/detail/serialization/miniz.*), and since it's already a part of libstudxml (i.e. a grandchild dependency), xlnt is now using libstudxml's expat (third-party/libstudxml/xml/details/expat).

The following steps will install the latest GCC compiler from source (you will notice that we installed GCC 6 using apt-get, this was a building block to the next step of getting GCC 6.3.0 - the latest compiler available at present).
Download gcc 6.3.0 from https://gcc.gnu.org/mirrors.html I used the Japanese mirror as this is the closest location to me http://ftp.tsukuba.wide.ad.jp/software/gcc/releases/gcc-6.3.0/gcc-6.3.0.tar.gz

If the above make command fails please use "make clean pristine" and then remove and remake the build directory. This will clean up and prepare the environment for another attempt. A common reason for failure on virtual machines is lack of RAM (if you don't have enough RAM you may get an error like this "recipe for target 's-attrtab' failed"). Otherwise, if all goes well in about 30 to 60 minutes the compiler will be ready and we will move on to the next steps.
