Overhaul versioning and naming of libraries This commit contains several changes to the naming and versioning of shared and static libraries. The details are documented at: https://github.com/mesonbuild/meson/pull/417 Here's a brief summary: * The results of binary and compiler detection via environment functions are now cached so that they can be called repeatedly without performance penalty. This is necessary because every build.SharedLibrary object has to know whether the compiler is MSVC or not (output filenames depend on that), and so the compiler detection has to be called for each object instantiation. * Linux shared libraries don't always have a library version. Sometimes only soversions are specified (and vice-versa), so support both. * Don't use versioned filenames when generating DLLs, DLLs are never versioned using the suffix in the way that .so libraries are. Hence, they don't use "aliases". Only Linux shared libraries use those. * OS X dylibs do not use filename aliases at all. They only use the soversion in the dylib name (libfoo.X.dylib), and that's it. If there's no soversion specified, the dylib is called libfoo.dylib. Further versioning in dylibs is supposed to be done with the -current_version argument to clang, but this is TBD. https://developer.apple.com/library/mac/documentation/DeveloperTools/Conceptual/DynamicLibraries/100-Articles/DynamicLibraryDesignGuidelines.html#//apple_ref/doc/uid/TP40002013-SW23 * Install DLLs into bindir and import libraries into libdir * Static libraries are now always called libfoo.a, even with MSVC * .lib import libraries are always generated when building with MSVC * .dll.a import libraries are always generated when building with MinGW/GCC or MinGW/clang * TODO: Use dlltool if available to generate .dll.a when .lib is generated and vice-versa. * Library and executable suffix/prefixes are now always correctly overriden by the values of the 'name_prefix' and 'name_suffix' keyword arguments.
