cbd3e61c8d Unicode collation algorithm: contraction support. 
E.g. 'Ch' is treated as a separate letter in Czech,
not as a combination of C+h.

c64d93b274 Allocate memory when a character set is requested: 
- For simple character sets: from_uni convertion table.
- For UCA: alternative weight arrays.
Use mbminlen instead of MY_CS_NONTEXT

(isn't it obvious ?)

e0a0790ebb Fixed that multibyte charsets didn't honor multibyte 
sequence boundaries in functions LIKE and LOCATE in
the case of "binary" collation. Comparison was done
like if the strings were just a binary strings without
character set assumption.

We don't need separate hash_sort() and hash_caseup()
  We don't need tosort(). strnxfrm will do the same.
