grep: prefer signed to unsigned integers
This improves runtime checking for integer overflow when compiling
with gcc -fsanitize=undefined and the like. It also avoids
the need for some integer casts, which can be error-prone.
* bootstrap.conf (gnulib_modules): Add idx.
* src/dfasearch.c (struct dfa_comp, kwsmusts):
(possible_backrefs_in_pattern, regex_compile, GEAcompile)
(EGexecute):
* src/grep.c (struct patloc, patlocs_allocated, patlocs_used)
(n_patterns, update_patterns, pattern_file_name, poison_len)
(asan_poison, fwrite_errno, compile_fp_t, execute_fp_t)
(buf_has_encoding_errors, buf_has_nulls, file_must_have_nulls)
(bufalloc, pagesize, all_zeros, fillbuf, nlscan)
(print_line_head, print_line_middle, print_line_tail, grepbuf)
(grep, contains_encoding_error, fgrep_icase_available)
(fgrep_icase_charlen, fgrep_to_grep_pattern, try_fgrep_pattern)
(main):
* src/kwsearch.c (struct kwsearch, Fcompile, Fexecute):
* src/kwset.c (struct trie, struct kwset, kwsalloc, kwsincr)
(kwswords, treefails, memchr_kwset, acexec_trans, kwsexec)
(treedelta, kwsprep, bm_delta2_search, bmexec_trans, bmexec)
(acexec):
* src/kwset.h (struct kwsmatch):
* src/pcresearch.c (Pcompile, Pexecute):
* src/search.h (mb_clen):
* src/searchutils.c (kwsinit, mb_goback, wordchars_count)
(wordchars_size, wordchar_next, wordchar_prev):
Prefer idx_t to size_t or ptrdiff_t for nonnegative sizes,
and prefer ptrdiff_t to size_t for sizes plus error values.
* src/grep.c (uword_size): New constant, used for signed
size calculations.
(totalnl, add_count, totalcc, print_offset, print_line_head, grep):
Prefer intmax_t to uintmax_t for wide integer calculations.
(fgrep_icase_charlen): Prefer ptrdiff_t to int for size offsets.
* src/grep.h: Include idx.h.
* src/search.h (imbrlen): New function, like mbrlen except
with idx_t and ptrdiff_t.
