  Log:
    * regparse.c (PINC): use optimized enclen() instead of
      ONIGENC_MBC_ENC_LEN().
    
    * regparse.c (PFETCH): ditto.
    
    * regparse.c (PFETCH): small optimization.
    
    * regexec.c (slow_search): single byte encoding optimization.
    
    * regenc.h (enclen): avoid calling function when encoding's
      min_len == max_len.
    
    * re.c (rb_reg_regsub): rb_enc_ascget() optimization for single
      byte encoding.
    
    * re.c (rb_reg_search): avoid allocating new re_registers if we
      already have MatchData.
    
    * re.c (match_init_copy): avoid unnecessary onig_region_free()
      before onig_region_copy. 
    
    * encoding.c (rb_enc_get_index): remove implicit enc_capable check
      each time.
    
    * encoding.c (rb_enc_set_index): ditto.
    
    * encoding.c (enc_compatible_p): small refactoring.
    
    * include/ruby/encoding.h (rb_enc_dummy_p): inline
      rb_enc_dummy_p() and export related code.
