Solaris sys/select.h switches select to select_large_fdset to support larger

But Ruby doesn't change FD_SETSIZE because fd_set is allocated dynamically.

* this commit is a result of refactoring. only renaming functions, moving definitions place, add/remove prototypes, deleting unused variables and removing yarv.h. This commit doesn't change any behavior of ruby/vm. * yarv.h, common.mk: remove yarv.h (contents are moved to yarvcore.h). * error.c, eval_intern.h: include yarvcore.h instead yarv.h * rename some functions: * debug.[ch]: debug_*() -> ruby_debug_*() * iseq.c: iseq_*() -> rb_iseq_*(), ruby_iseq_disasm() * iseq.c: node_name() -> ruby_node_name() * vm.c: yarv_check_redefinition_opt_method() -> rb_vm_check_redefinition_opt_method() * some refactoring with checking -Wall. * array.c: remove rb_ary_ptr() (unused) and remove unused local variables. * object.c: add a prototype of rb_mod_module_exec(). * eval_intern.h (ruby_cref): set it inline. * eval_load.c (rb_load), yarvcore.c: yarv_load() -> rb_load_internal(). * parse.y: add a prototype of rb_parse_in_eval() (in eval.c). * process.c: add a prototype of rb_thread_stop_timer_thread() (in thread.c). * thread.c: remove raw_gets() function (unused) and fix some format mismatch (format mismatchs have remained yet. this is todo). * thread.c (rb_thread_wait_fd_rw): fix typo on label name. * thread_pthread.ci: comment out codes with USE_THREAD_CACHE. * vm.c (rb_svar, rb_backref_get, rb_backref_get, rb_lastline_get, rb_lastline_set) : moved from yarvcore.c. * vm.c (yarv_init_redefined_flag): add a prototype and rename yarv_opt_method_table to vm_opt_method_table. * vm.c (rb_thread_eval): moved from yarvcore.c. * yarvcore.c: remove unused global variables and fix to use nsdr(). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@11652 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
