55239b4ba7 Setting a variable to the same value twice doesn't actually make it 
more likely to have the right value.  Remove superfluous assignments.

45f0d08992 Mark functions as __dead2 in order to help the LLVM static checker 
understand which code paths aren't possible.

This commit eliminates 117 false positive bug reports of the form
"allocate memory; error out if pointer is NULL; use pointer".

08fb11c891 Fix a longstanding bug, from Otto Moerbeck: 
if we're reducing a rule that has an empty
right hand side and the yacc stackpointer is pointing at the very
end of the allocated stack, we end up accessing the stack out of
bounds by the implicit $$ = $1 action

Use the literal string 'PWB UNIX', as we still have no .At macro for it.

d9613ea383 Style improvements recommended by Bruce as a follow up to some 
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

668e3ec014 Fixed breakage of K&R support in rev.1.26. yyparse() was defined as 
`int yyparse(;) ; { ... }' in K&R mode.  Getting rid of the second
unwanted semicolon in this made the ifdef tangle more tangled than
before.  Fixed a backwards comment in the tangle.
