tdf#116666 Hungarian collation: casing and equality fixes

Casing fixes: “CCS” sorted as “CSCS”, not “cscs”.
“Ccs” and “CCS” are capitalized versions of the simplified
double consonant “cs”, but “CCs” is an abbreviation of words
beginning with “C” and “Cs” (similar to “AkH.”, “MHSz.”) etc.

To avoid the comparison result “equal” we set a precedence
between the simplified and compound-like long forms, too.
For example, “ésszerű” (old orthography before 2015) and
“észszerű” (not “észszerű”, “ésszerű”), or “mennyelv” and
“menynyelv” (words with different meanings) sorted as
“észszerű” and “észSzerű”, also “menynyelv” and “menyNyelv”.

+# We expand simplified double consonants, for example,
+# "ccs" sorted as "cscs". This is still not an error-free
+# method, but better, than the old method, because now
+# it's *possible* to fix all errors in a semi-automatic way,
+# using soft hyphens. Inserting them in bad or ambiguous
+# character positions will fix all automatic sortings later,
+# for example, “arccsont” -> “arc|csont” (“|” signs soft
+# hyphen position).
