Moved from string.h to deprecated.h. * deprecated.c, deprecated.h (SCM_CHARS, SCM_LENGTH): Removed. * strings.h, strings.c (SCM_MAKE_STRING_TAG): Rename dto SCM_I_MAKE_STRING_TAG, changed all uses. (SCM_STRING_CHARS, SCM_STRING_UCHARS, SCM_STRING_LENGTH): Renamed to SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_LENGTH respectively. For a short time, the old names are still there as aliases. Not all uses have been changed yet, but the ones in strings.c have. (SCM_STRING_MAX_LEN): Do not hardcode to 24 bits, compute from SCM_T_BITS_MAX. (scm_is_string, scm_from_locale_string, scm_from_locale_stringn, scm_take_locale_string, scm_take_locale_stringn, scm_to_locale_string, scm_to_locale_stringn, scm_to_locale_stringbuf): New. (scm_c_string2str, scm_c_substring2str): Deprecated by moving to deprecated.[hc]. Implemented in terms of the new functions above. (scm_take_str, scm_take0str, scm_mem2string, scm_str2string, scm_makfrom0str): Reimplemented in terms of the new functions from above. They will be discouraged shortly. (scm_substring): Do not use scm_mem2string. (scm_i_allocate_string_pointers, scm_i_free_string_pointers): New, to replace similar code from posix.c, simpos.c, and dynl.c. (scm_string_append): Use memcpy instead of explicit loop. Do not use register keyword. Use plain 'char' instead of 'unsigned char'.
