* sort and comment remaining unsorted filter patterns in suspiciousTests
(mostly just move to TODO and state what needs to be done).
* comment the patterns for achemso and Math,
(LuTeX incompatibility fixed in TeXLive 2016-01-07).
Simplify the logic for language package selection and make it more consistent:
Use polyglossia with non-TeX fonts (system fonts/Unicode fonts) for all
export flavours (XeTeX, LuaTeX, DVI-LuaTeX), if the language package setting
is "auto" and there is no language not supported by Babel and no package
providing Babel.
This solves some Babel-related autotest cases and leads to some new failures
due to the polyglossia language nesting problem.
* missing characters in linguistics example with system fonts
* language nesting problem in fr/linguistics example
* 110f505b63 solved one failure (Basque example file)
Works with system-fonts due to font substitution in the test-script.
TODO: set system fonts that work in the lyx source(s) to allow compilation
"by hand".
testcases_speed_lyx21 added to suspiciousTests
Handling unknown body token: `\begin_manifest'at line ...
Literate_lyx16 and noweb2lyx_lyx16 added to ignoredTests
Plenty of warnings (~ 390)
New sublabels LyXBug, ERT.
Renamed sublabel TeXLimit to TeXissue.
More sorting and unification of regular expressions.
Removing double entries.
Fixes for some expressions (eu_UserGuide_pdf, examples/ja/(knitr|lilypond|sweave))
Since the stop condition is that the last two consecutive created
files are identical, we do not need to check the last file.
Also checking for load of the created files is not needed, because
exporting the previous file implicitly loads too.
Exporting to some previous lyx format:
Inside the loop
Stop at export with errors/warnings
Stop if exported file not loadable
Stop if exported file identical to previous exported file (OK case)
This is done through creating MD5SUM
We test here, if any \end_{somethig} matches \begin_{something}.
Exeptions are \end_index and \end_branch ATM, they should
match \index and \branch respectively.
Also added new testfile.
