Int cleanup and minor reorganization to be more like src/expand.c.

Include quote.h, xstrndup.h.
(TAB_STOP_SENTINEL): Increase from INT_MAX to INTMAX_MAX.
(convert_entire_line, have_read_stdin, parse_tabstops, next_file,
unexpand, main):
Use bool for booleans.
(tab_size, tab_list, add_tabstop, validate_tabstops, unexpand):
Use uintmax_t for column counts.
(first_free_tab, validate_tabstops, unexpand): Use size_t for sizes.
(add_tabstop, parse_tabstops, main): Don't reserve UINTMAX_MAX
as a tab stop.
(parse_tabstops): Don't use ISBLANK on possibly-signed char.
Detect overflow in tab stop string.
(next_file, main): Use EXIT_FAILURE/EXIT_SUCCESS instead of 1/0.
(unexpand): Concatenate input files the same way expand does.
