Fix Mongolian Variation Selectors for fonts without GDEF Originally we fixed those in 79d1007a501fd63c0ba4d51038c513e6b8b94740. However, fonts like MongolianWhite don't have GDEF, but have IgnoreMarks in their LigatureSubstitute init/etc features. We were synthesizing a GDEF class of mark for Mongolian Variation Selectors and as such the ligature lookups where not matching. Uniscribe doesn't do that. I tried with more sophisticated fixes, like, if there is no GDEF and a lookup-flag mismatch happens, instead of rejecting a match, try skipping that glyph. That surely produces some interesting behavior, but since we don't want to support fonts missing GDEF more than we have to, I went for this simpler fix which is to always mark default-ignorables as base when synthesizing GDEF. Micro-test added. Fixes rest of https://bugs.freedesktop.org/show_bug.cgi?id=65258

Another try to fix Mongolian free variation selectors This reverts bf029281 and fixes it properly. That commit was not enough as it was only inheriting the shaping_action for prev_action, but not curr_action. Micro-test added. https://code.google.com/p/chromium/issues/detail?id=393896
