* include/ruby/ruby.h (struct RRegexp): new field usecnt. replace
str and len by src.
* gc.c (gc_mark_children): mark src field of regexp.
(obj_free): don't free str field.
* re.c (REG_BUSY): removed.
(rb_reg_initialize): prohibit re-initialize regexp.
(rb_reg_search): use usecnt to prevent freeing regexp currently
using. this prevents SEGV by:
r = /\A((a.)*(a.)*)*b/
r =~ "ab" + "\xc2\xa1".force_encoding("euc-jp")
t = Thread.new { r =~ "ab"*8 + "\xc2\xa1".force_encoding("utf-8")}
sleep 0.2
r =~ "ab"*8 + "\xc2\xa1".force_encoding("euc-jp")
