String comparison with utf8_bin collation is case sensitive.
Hence "DELIMITER" did not match with "delimiter".
The delimiter command matching now uses my_charset_latin1.
Added version_source_revision server "variable", for the git revision.
Also , mysql -V will show git revision.
"make dist" will now pack source_revision.h into the source package.
DESCRIPTION:
===========
The bug is related to incorrect parsing of SQL queries
when typed in on the CLI. The incorrect parsing can
result in unexpected results.
ANALYSIS:
========
The scenarios mainly happens for identifier names
with a typical combination of backslashes and backticks.
The incorrect parsing can either result in executing
additional queries or can result in query truncation.
This can impact mysqldump as well.
FIX:
===
The fix makes sure that such identifier names are
correctly parsed and a proper query is sent to the
server for execution.

When there are quotes in the USE statement, the mysql client does
not correctly escape them.
The USE statement is processed line by line from the client's parser,
and cannot handle multi-line commands as the server.
The fix is to escape the USE parameters whenever quotes are used.
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.
MYSQL_OPT_SSL_MODE option introduced.
It is set in case of --ssl-mode=REQUIRED and permits only SSL connection.
(cherry picked from commit 3b2d28578c526f347f5cfe763681eff365731f99)
An addition to original patch:
- use FN_REFLEN instead of HOST_NAME_MAX (the latter can be undefined)
- avoid calling gethostname() on every prompt construction by caching it
