OTP-8449 Documentation improvements.

          The most important "readme" files now use Markdown notation. HTML
          versions of these files are now also automatically generated and
          included in the HTML documentation.

          - Building and Installing Erlang/OTP - $ERL_TOP/INSTALL.md
          (previously known as $ERL_TOP/README).

          - Cross Compiling Erlang/OTP - $ERL_TOP/INSTALL-CROSS.md.

          - How to Build Erlang/OTP on Windows - $ERL_TOP/INSTALL-WIN32.md
          (previously known as $ERL_TOP/README.win32).
