Description:
in .../libmysql/charset.c, MAX_BUF is 16k, I believe it's supposedly to read the file into buf
in one shot, but .../share/mysql/charsets/Index.xml is larger than 16k. Later on in
my_parse_charset_xml(), the parsing will overstep beyond buf. 

How to repeat:
check the src

Suggested fix:
Increase MAX_BUF or change the way file is read into buf in my_read_charset_file().

Verified against 4.1.2.  Only MAX_BUF bytes will be read, with Index.xml already exceeding this size.  Add a charset at the end to see that this is the case.

Thank you.
