[PATCH 2/4] more transparent dealing with tokens/position

[Jan Pokorný <pokorny_jan@xxxxxxxxx>]

Unify usage of `eof_token'.

Version with respective assertions added will be provided,
mainly for convenient testing.  I used it to proceeded sparse itself
and linux-2.6.35.12 sources with no assertion violation encountered.
