* bootstrap.conf: Use c_strtod, so that even in French locales "1.5"
is accepted, instead of "1,5".
* src/counterexample.c, src/state-item.c: Use xtime_t instead of
time_t, so that accuracy goes from seconds to nanoseconds.
( counterexample_init): Depend on cex.timeout rather than
$TIME_LIMIT.
* doc/bison.texi (%define Summary): Document cex.timeout.
It is not available on HP-UX 11i.

Gnulib provides no replacement, but anyway we should be using doubles,
since difftime uses doubles.
* bootstrap.conf: We want portability on stdtod.
* src/counterexample.c: Use double, not float, for time measurements.
Don't repeatedly call malloc/free for each call to map_file_name.
* bootstrap.conf: We need hash-map.
* src/files.h, src/files.c (map_file_name): The caller must not free
the result.
Adjust callers.
(mapped_dir_prefix, spec_mapped_header_file): Remove.
* src/files.c
(map_file_name): Rename as...
(map_file_name_alloc): this.
(mapped_files, map_file_name, string_equals, string_hash, string_free):
New.
Use of print_unicode_char suggested by Bruno Haible.

* src/gram.h (print_dot_fallback, print_dot): New.
* src/gram.c, src/derivation.c: Use it.
* tests/counterexample.at, tests/report.at: Adjust the test suite.
* .travis.yml, README-hacking.md: Adjust.
* gnulib: Update.
* bootstrap.conf: Use attribute.
* src/system.h: Remove macros for attributes.
Adjust dependencies.
* src/scan-gram.l (DEPRECATED): Rename as...
(DEPRECATED_DIRECTIVE): this, to avoid the clash with the DEPRECATED macro.
From

to
input.y:1.17-19: warning: symbol 'baz' is used, but is not defined as a token and has no rules; did you mean 'bar'? [-Wother]
1 | %printer {} foo baz

* bootstrap.conf: We need fstrcmp.
* src/symtab.c (symbol_from_uniqstr_fuzzy): New.
(complain_symbol_undeclared): Use it.
* tests/diagnostics.at (Suggestions): New.
* data/bison-default.css (insertion): Rename as...
(fixit-insert): this, as this is what GCC uses.
So far diagnostics were cheating: in addition to the 'column' field of
locations (based on actual screen width per multibyte characters and
on tabulation expansion), the scanner sets the 'byte' field.
Diagnostics used this byte count to decide where to insert (color)
style.
We want to be able to truncate the quoted lines when there are too
wide to fit the screen. This requires that the diagnostics learn how
to count columns, the byte-in-boundary trick no longer works.
Bytes are still used for fix-its.
* bootstrap.conf: We need mbfile for mbf_getc.
* src/location.c (caret_info): We need an mbfile.
(caret_set_file): Initialize it.
(caret_getc): Convert to mbfile.
(location_caret): Instead of relying on the byte position to decide
where to insert the color style, count the current column using
boundary_compute.
Bruno Haible just added a default implementation of libtextstyle's
interface when the library is not available.
https://lists.gnu.org/archive/html/bison-patches/2019-03/msg00025.html
* gnulib: Update.
* bootstrap.conf: Replace libtextstyle with libtextstyle-optional.
* src/complain.c, src/getargs.c: Remove now useless cpp guards.
Introduce proper support for fixits, instead of just printing them on
demand.
* bootstrap.conf: We need gnulib's xlists.
* src/fixits.h, src/fixits.c: New.
* src/complain.c (deprecated_directive): Use fixits_register.
* src/main.c (main): Use fixits_free.

This is very easy to do, thanks to work by Bruno Haible in gnulib.
See "Supporting Relocation" in gnulib's documentation.
* bootstrap.conf: We need relocatable-prog and relocatable-script (for yacc).
* src/yacc.in: New.
* configure.ac, src/local.mk: Instantiate it.
* src/main.c, src/output.c (main, pkgdatadir): Use relocatable2.
* doc/bison.texi (FAQ): Document it.
* README-hacking: Commit before bootstrapping.
* bootstrap.conf: gnulib_mk is no longer defined by bootstrap.
* bootstrap, gnulib, lib/.gitignore, m4/.gitignore: Update/regen.
