Subject: [PATCH 1/4] Fix code generated for Ruby global variables
This commit fixes swig#1653 by creating a Ruby virtual variable
for a C/c++ global variable when SWIG is invoked with the
-globalmodule option.

Subject: [PATCH 2/4] Add support for Ruby 2.7
This commit fixes the signatures of various callback methods
and cleans up the macro definitions used for casting callbacks.
Note that the transparent version of the macro RUBY_METHOD_FUNC
is currently masked behind RUBY_DEVEL, see commit
https://github.com/ruby/ruby/commit/1d91feaf13e0ffe04b2dabc6e77e4101b6d0bb07
In order to still support strict signature checking and prevent
nasty deprecation warnings, the use of RUBY_METHOD_FUNC had to
be replaced with VALUEFUNC.

Subject: [PATCH 4/4] Improve description of cast macros for Ruby
The macros for casting function pointers are now fully described and also
clarify why the macros act transparently for C even before Ruby 2.7.
In addition, an "if (CPlusPlus)" was removed in the code generator for
global variables in order to keep the distinction between C and C++ in
one place, which is at the definition of said macros.

- * Need to be very careful about how these macros are defined, especially
- * when compiling C++ code or C code with an ANSI C compiler.
+ * The following macros are used for providing the correct type of a
+ * function pointer to the Ruby C API.
+ * Starting with Ruby 2.7 (corresponding to RB_METHOD_DEFINITION_DECL being
+ * defined) these macros act transparently due to Ruby's moving away from
+ * ANYARGS and instead employing strict function signatures.
*
- * VALUEFUNC(f) is a macro used to typecast a C function that implements
- * a Ruby method so that it can be passed as an argument to API functions
- * like rb_define_method() and rb_define_singleton_method().
+ * Note: In case of C (not C++) the macros are transparent even before
+ * Ruby 2.7 due to the fact that the Ruby C API used function declarators
+ * with empty parentheses, which allows for an unspecified number of
+ * arguments.
*
- * VOIDFUNC(f) is a macro used to typecast a C function that implements
- * either the "mark" or "free" stuff for a Ruby Data object, so that it
