[PATCH] Convert underscores to dashes in some %define variable names.

[Joel E. Denny]

I know we're waiting until at least 2.6 for most of the renaming, but I 
feel the following couple of renames are stable enough:

1. api.push_pull -> api.push-pull.  It hasn't evolved for a while.  
Besides, it's still labeled experimental.

2. lr.keep_unreachable_states -> lr.keep-unreachable-states.  It's a 
Boolean, unfortunately, but I think it's obscure enough that it won't 
evolve any time soon.

The old names are deprecated but still supported.

I pushed the following patch to branch-2.5 and a similar one to master.

Subject: [PATCH] Convert underscores to dashes in some %define variable names.

For now, just api.push-pull and lr.keep-unreachable-states.
Maintain old names for backward compatibility.
* NEWS (2.5): Document.
* data/c.m4 (b4_identification): Update comment.
* data/yacc.c: Update access.
* doc/bison.texinfo: Update.
* etc/bench.pl.in (bench_grammar): Update use.
* src/files.c (tr): Move to...
* src/getargs.c, src/getargs.h (tr): ... here because I can't
think of a better place to expose it.  My logic is that, for all
uses of tr so far, command-line arguments can be involved, and
getargs.h is already included.
* src/main.c (main): Update access.
* src/muscle_tab.c (muscle_percent_define_insert): Convert old
variable names to new variable names before assigning value.
* src/reader.c (reader): Update setting default.
* tests/calc.at: Update uses.
* tests/conflicts.at (Unreachable States After Conflict
Resolution): Update use.
* tests/input.at (%define enum variables): Update use.
(%define backward compatibility): New test group.
* tests/push.at: Update uses.
* tests/reduce.at: Update uses.
* tests/torture.at: Update uses.
