Added ninja lexers to tests.

Note: ninja_lexer.ib.c differs from the original lexer in the ninja project,
because the latter was generated with re2c-0.16, which used slightly
different constructs for complex expressions:

Re2c-0.16 used generated something like this:

    ++YYCURSOR;
    if (yych = *YYCURSOR) ...

And the latest re2c generates something like this:

    yych = *++YYCYRSOR;
    if (yych) ...

The difference is insignificant.

libre2c: added prefix 'TOKEN_' to all parser tokens to avoid name collisions.

Apparently some versions of bison generate token definitions as macros, not
as enum members. If a bison-generated header is included into another file
that contains identifiers identical to the names of parser tokens, all such
identifiers are macro-substituted to a numeric constant. Adding a prefix to
token names reduces the chances of name collision.
