Add Autotools based build system
 * Also support various `ANCIENT_API`_foo macros in `<ancient/ancient.hpp>` in order to avoid having to define macros containing all kinds of escaping-requiring characters from the build system. The supported common cases are `ANCIENT_API_VISIBILITY_DEFAULT` (any modern Unix-like system), `ANCIENT_API_VISIBILITY_DEFAULT_USED` (some Emscripten targets), and `ANCIENT_API_DECLSPEC_DLLEXPORT`/`ANCIENT_API_DECLSPEC_IMPORT` (Windows). * Rename old `Makefile` to `Makefile.unix`. This avoids the name conflict with the automake `Makefile` generated by `configure`. * Add autoconf/automake/libtool/pkg-config build system. The old build system stays functional (albeit with a non-standard `Makefile.unix` name). A simple work-around to just continue with the old build system is to use `ln -s Makefile.unix Makefile` while developing. * Introduce package versioning (using SemVer) and soname versioning via libtool. Details are documented at the top of `configure.ac`. * Release tarballs can now be generated either as before via a direct repository snapshot, or via `make distcheck`.
