Support loading builtin features written in Ruby, which implement with C builtin functions. [Feature #16254] Several features: (1) Load .rb file at boottime with native binary. Now, prelude.rb is loaded at boottime. However, this file is contained into the interpreter as a text format and we need to compile it. This patch contains a feature to load from binary format. (2) __builtin_func() in Ruby call func() written in C. In Ruby file, we can write `__builtin_func()` like method call. However this is not a method call, but special syntax to call a function `func()` written in C. C functions should be defined in a file (same compile unit) which load this .rb file. Functions (`func` in above example) should be defined with (a) 1st parameter: rb_execution_context_t *ec (b) rest parameters (0 to 15). (c) VALUE return type. This is very similar requirements for functions used by rb_define_method(), however `rb_execution_context_t *ec` is new requirement. (3) automatic C code generation from .rb files. tool/mk_builtin_loader.rb creates a C code to load .rb files needed by miniruby and ruby command. This script is run by BASERUBY, so *.rb should be written in BASERUBY compatbile syntax. This script load a .rb file and find all of __builtin_ prefix method calls, and generate a part of C code to export functions. tool/mk_builtin_binary.rb creates a C code which contains binary compiled Ruby files needed by ruby command.
