Georgi Kodinov b4766fc36a Bug #51876: crash/memory underrun when loading data with ucs2 ...

and reverse() function
      
3 problems fixed : 
1. The reported problem : caused by incorrect parsing of 
the file as ucs data resulting in wrong length of the parsed
string. Fixed by truncating the invalid trailing bytes 
(non-complete multibyte characters) when reading from the file
2. LOAD DATA when reading from a proper UCS2 file wasn't 
recognizing the new line characters. Fixed by first looking 
if a byte is a new line (or any other special) character before
reading it as a part of a multibyte character.
3. When using user variables to hold the column data in LOAD
DATA the character set of the user variable was set incorrectly
to the database charset. Fixed by setting it to the charset
specified by LOAD DATA (if any).
