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.

use register keyword. Use plain 'char' instead of 'unsigned
char'.
trying to throw an exception -- call scm_misc_error with correct
arguments. The previous arguments needed a format escape that
wasn't in any of the format strings.
