* runtime/string.c (compare0): Use gfc_charlen_type.
* runtime/error.c (gfc_itoa): Move to io/write.c
(xtoa): Rename to gfc_xtoa.
* runtime/backtrace.c (show_backtrace): Call gfc_xtoa.
* intrinsics/cshift0.c (cshift0): Use index_type for shift arg.
* intrinsics/date_and_time.c (date_and_time): Use index_type.
(itime_i4): Likewise.
(itime_i8): Likewise.
(idate_i4): Likewise.
(idate_i8): Likewise.
(gmtime_i4): Likewise.
(gmtime_i8): Likewise.
(ltime_i4): Likewise.
(ltime_i8): Likewise.
* libgfortran.h (gfc_itoa): Remove prototype.
(xtoa): Rename prototype to gfc_xtoa.
* io/list_read.c (nml_read_obj): Use size_t for string length.
* io/transfer.c (read_block_direct): Change nbytes arg from
pointer to value.
(unformatted_read): Minor cleanup, call read_block_directly properly.
(skip_record): Use ssize_t.
(next_record_w_unf): Avoid stell() call by calling sseek with SEEK_CUR.
(iolength_transfer): Make sure to multiply before cast.
* io/intrinsics.c (fgetc): Remove unnecessary variable.
* io/format.c (format_hash): Use gfc_charlen_type.
* io/write.c (itoa): Move from runtime/error.c:gfc_itoa, rename,
make static.
(write_i): Call with pointer to itoa.
(write_z): Call with pointer to gfc_xtoa.
(write_integer): Pointer to itoa.
(nml_write_obj): Type cleanup, don't call strlen in loop.
