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

Created new .test file - mysqldump_restore that does this for a limited number
of basic cases.
Created 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.

+# 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!
