    Reader option to parse strings and chars using R6RS rules
    
    Add the capability to use some of R6RS's string and character syntax,

      strings according to R6RS
    
    * libguile/chars.c (scm_r6rs_charnames, scm_r6rs_charnums, 
SCM_N_R6RS_CHARNAMES):
      new constants of character names
      (scm_i_charname): output R6RS charnames
      (scm_i_charname_to_char): check for R6RS charnames
    
    * libguile/private-options.h (SCM_R6RS_OPTIONS_P): new define
    
    * libguile/read.c (scm_read_opts): add new option 'strict-r6rs-strings'
      (SCM_READ_HEX_ESCAPE): new codeblock to parse character hex escapes
      (SCM_READ_SPACE_LINE_SPACE): new codeblock to parse string backslashes
      (scm_read_string): read R6RS string escapes
