7e38c952e6 Bug fix - don't ignore non-dictionary objects when searching for the
linearization parameter dictionary.

Spec states that that linearization parameter dictionary must be the first
object.

0aa6b67eea In QPDFWordTokenFinder::check limit the token length
Tokens longer than the target cannot be a match and therefore there is no
need to read to the end of token.

06a2d955fc In QPDFParser add a limit on total number of errors in one object
Currently, QPDFParser gives up attempting to parse an object if 5
near-consecutive bad tokens are encountered. Add a limit of a total of 15
bad tokens in a single object before giving up.
