Bug#25340722 - PRINT BINARY DATA AS HEX IN THE MYSQL 

               CLIENT (CONTRIBUTION)

DESCRIPTION:
============
Binary data should be printed as hex in the mysql client
when the option binary-as-hex is enabled.

ANALYSIS:
=========
The fix deals only with mysql command line client.
It does not change, at all, the data sent to the
applications. Printing binary data as hex also
allows to use the output in the where clause
of the query.

FIX:
====
A new option 'binary-as-hex' is introduced to print the
binary contents as hex in the mysql client. The option
is disabled by default. When the option is enabled, we
convert the binary data to hex before printing the
contents irrespective of whether it is in tabular,
xml or html format.
