scm_fdes_to_port, but take mode bits directly instead of as a C string. (scm_i_fdes_to_port): Implement using above. (scm_open_file): Use scm_i_fdes_to_port together with scm_i_mode_bits to avoid accessing internals of SCM string from C. * vports.c (scm_make_soft_port): Use scm_i_fdes_to_port together with scm_i_mode_bits to avoid accessing internals of SCM string from C. * ports.h (scm_i_mode_bits): New, same as scm_mode_bits but with a SCM string as argument. * ports.c (scm_i_void_port): New, like scm_void_port but take mode bits directly instead of C string. (scm_void_port): Implement using above. (scm_sys_make_void_port): Use scm_i_void_port together with scm_i_mode_bits to avoid accessing internals of SCM string. * convert.i.c, backtrace.c, strop.c, strorder.c, strports.c, struct.c, unif.c, ports.c: Use SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_STRING_LENGTH instead of SCM_STRING_CHARS, SCM_STRING_UCHARS, and SCM_STRING_LENGTH, respectively. Also, replaced scm_return_first with more explicit scm_remember_upto_here_1, etc, or introduced them in the first place.
