Bug#40465 - mysqldump.test does no checking of dump or restore

Created new .test file - mysqldump_restore that does test restore from mysqldump
output for a limited number of basic cases.
Create new .inc file - mysqldump.inc - renames original table and uses mysqldump
output to recreate the table, then uses diff_tables.inc to compare the two tables.
Backported include/diff_tables.inc to facilitate this testing.
New patch incorporating review feedback prior to push.

mysqldump.test - removed redundant call to include/have_log_bin.inc (was used twice in the test!)

 # mysqldump.inc
+#
 # SUMMARY: include file to facilitate testing the quality of mysqldump output
+#
 # INPUTS:  Two variables:
 #          $table_name - the name of the table that was dumped
 #          $mysqldumpfile - the name of the file that captured mysqldump output
+#
 # OUTPUTS: minor echo data:
 #          We 'echo' some stage information to the .result file:
 #          'altering original table', 'restoring from dumpfile', 'comparing'
+#
 # OTHER FILES:  We use include/diff_tables.inc to compare the original, renamed
 #               table with the 'restored' one. 
+#
 # DESCRIPTION: This file works by being fed the name of the original table
 #              and a mysqldump output file.  The original table is then renamed
 #              to <table_name>_orig, the mysqldump file is used to recreate the
 #              table, then diff_tables.inc is called to compare them.
+#
 # LIMITATIONS:  Does *NOT* work with xml output!
