Improve version information
Add version number and string as macros and symbols. Version numbers can be easily compared, for example in the C preprocessor: #include <cmark.h> #if CMARK_VERSION < 0x020200 #error Requires libcmark 2.2.0 or higher #endif Storing the version in a global variable allows to check the library version at runtime. For example: if (CMARK_VERSION != cmark_version) { warn("Compiled against libcmark %s, but using %s", CMARK_VERSION_STRING, cmark_version_string); } The version should be updated whenever the public API is changed.
