Mass backport tex2lyx bug fixes.

tex2lyx is no identical with the version in trunk (except for cosmetic changes and file formats > 413). The output of the test cases is either unchanged or improved. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/branches/BRANCH_2_0_X@40364 a592a061-630c-0410-9148-cb99ea01b6c8
