diagnose too-large numbers better
Following on from commit v8.23-82-gaddae94, consistently diagnose numbers that are too large, so as to distinguish from other errors, and make the limits obvious. * gl/modules/xdectoint: A new module implementing xdecto[iu]max(), which handles the common case of parsing a bounded integer and exiting with a diagnostic on error. * gl/lib/xdectoimax.c: The signed variant. * gl/lib/xdectoint.c: The parameterized implementation. * gl/lib/xdectoint.h: The interface. * gl/lib/xdectoumax.c: The unsigned variant. * bootstrap.conf: Reference the new module. * cfg.mk (exclude_file_name_regexp--sc_require_config_h_first): Exclude the parameterized templates. * src/csplit.c: Output EOVERFLOW or ERANGE errors if appropriate. * src/fmt.c: Likewise. * src/fold.c: Likewise. * src/head.c: Likewise. * src/ls.c: Likewise. * src/nl.c: Likewise. * src/nproc.c: Likewise. * src/shred.c: Likewise. * src/shuf.c: Likewise. * src/stdbuf.c: Likewise. * src/stty.c: Likewise. * src/tail.c: Likewise. * src/truncate.c: Likewise. * src/split.c: Likewise. * src/pr.c: Likewise. * tests/pr/pr-tests.pl: Adjust to avoid matching errno diagnostic. * tests/fmt/base.pl: Likewise. * tests/split/l-chunk.sh: Likewise. * tests/misc/shred-negative.sh: Likewise. * tests/misc/tail.pl: Likewise. Also remove the redundant existing ERR_SUBST from test err-6. * tests/ls/hex-option.sh: Check HEX/OCT options. * tests/misc/shred-size.sh: Likewise. * tests/misc/stty-row-col.sh: Likewise.
