Paul Eggert fb9c0b3360 Use unlocked I/O for a minor performance improvement on hosts like
GNU/Linux and Solaris that support unlocked I/O.  The basic idea
is to use the gnlib unlocked-io module, and to prefer putc and
puts to printf when either will work (since the latter doesn't
come in an unlocked flavor).
* bootstrap (gnulib_modules): Add unlocked-io.
* data/c.m4 (yysymprint): Prefer puts and putc to printf.
* data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.
Prefer them to YYFPRINTF and YYDPRINTF if either will do,
and similarly for puts and putc and printf.
* data/yacc.c: Likewise.
* lib/bitset.c (bitset_print): Likewise.
* lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.
* lib/bitsetv.c (bitsetv_dump, debug-bitsetv): Prefer putc and puts
to printf.
* lib/lbitset.c (debug_lbitset): Likewise.
* src/closure.c (print_firsts, print_fderives): Likewise.
* src/gram.c (grammar_dump): Likewise.
* src/lalr.c (look_ahead_tokens_print): Likewise.
* src/output.c (escaped_output): Likewise.
(user_actions_output): Coalesce two printfs.
* src/parse-gram.h (%printer): Prefer putc and puts to printf.
* src/reduce.c (reduce_print): Likewise.
* src/state.c (state_rule_look_ahead_tokens_print): Likewise.
* src/system.h: Include unlocked-io.h rathe than stdio.h.

This directory contains Bison skeletons: the general shapes of the
different parser kinds, that are specialized for specific grammars by
the bison program.

Currently, there are only three supported skeletons:

- yacc.c
  It used to be named bison.simple: it corresponds to C Yacc
  compatible LALR(1) parsers.

- lalr1.cc
  Produces a C++ parser class.  It is still very experimental, and not
  yet supported.  Please, subscribe to bison-patches@gnu.org.

- glr.c
  A Generalized LR C parser based on Bison's LALR(1) tables.

These skeletons are the only ones supported by the Bison team.
Because the interface between skeletons and the bison program is not
finished, *we are not bound to it*.  In particular, Bison is not
mature enough for us to consider that ``foreign skeletons'' are
supported.
