InnoDB fix will come in MDEV-13360.
Here I just fix upgrades from old unfixed InnoDBs - bad data
makes the following copying ALTER TABLE to fail.

===========
When doing an upgrade, you execute mysql_upgrade. If
mysql_upgrade fails to connect or it connects with a user
without the proper privileges, it will return the error:
FATAL ERROR: Upgrade failed
which is not very informative.
ANALYSIS
========
In main() and check_version_match(), the condition for
errors are clubbed together and throw the same error msg.
The functions need to be splitted up and the corresponding
error msgs have to be displayed.
FIX
===
Splitted the functions and added the specific error msg.

OPTION SKIP-WRITE-BINLOG
System tables were not getting upgraded when
mysql_upgrade was run with --skip-write-binlog
option. (Same for --write-binlog.) Also, with
this option, mysql_upgrade_info file was not
getting created after the upgrade.
mysql_upgrade makes use of mysql client tool in
order to run upgrade scripts, while doing so it
passes some of the command line options (used to
start mysql_upgrade) directly to mysql client.
The reason behind this bug being, some options
like skip-write-binlog and upgrade-system-tables
were being passed to mysql tool along with other
options, and hence mysql execution failed due
presence of these invalid options.
Fixed this issue by filtering out the above mentioned
options from the list of options that will be passed to
mysql and mysqlcheck tools. However, since --write-binlog
is supported by mysqlcheck, this option would be used
explicitly while running mysqlcheck. (not part of patch,
already there)
Checking the contents of general log after the upgrade
is not doable via an mtr test. So performed manual test.
Added a test to verify the creation of mysql_upgrade_info.

1. Fixed the name of the table to proxies_priv
2. Fixed the column names to be of the form Capitalized_lowecarse instead of
Capitalized_Capitalized
3. Added Timestamp and Grantor columns
4. Added tests to plugin_auth to check the table structure
5. Updated the existing tests

REPAIR of merge table
Bug #56422 CHECK TABLE run when the table is locked reports
corruption along with timeout
The crash happened if a table maintenance statement (ANALYZE TABLE,
REPAIR TABLE, etc.) was executed on a MERGE table and opening and
locking a child table failed. This could for example happen if a child
table did not exist or if a lock timeout happened while waiting for
a conflicting metadata lock to disappear.
Since opening and locking the MERGE table and its children failed,
the tables would be closed and the metadata locks released.
However, TABLE_LIST::table for the MERGE table would still be set,
with its value invalid since the tables had been closed.
This caused the table maintenance statement to try to continue
and upgrade the metadata lock on the MERGE table. But since the lock
already had been released, this caused a segfault.
This patch fixes the problem by setting TABLE_LIST::table to NULL
if open_and_lock_tables() fails. This prevents maintenance
statements from continuing and trying to upgrade the metadata lock.
The patch includes a 5.5 version of the fix for
Bug #46339 crash on REPAIR TABLE merge table USE_FRM.
This bug caused REPAIR TABLE ... USE_FRM to give an assert
when used on merge tables.
The patch also enables the CHECK TABLE statement for log tables.
Before, CHECK TABLE for log tables gave ER_CANT_LOCK_LOG_TABLE,
yet still counted the statement as successfully executed.
With the changes to table maintenance statement error handling
in this patch, CHECK TABLE would no longer be considered as
successful in this case. This would have caused upgrade scripts
to mistakenly think that the general and slow logs are corrupted
and have to be repaired. Enabling CHECK TABLES for log tables
prevents this from happening.
Finally, the patch changes the error message from "Corrupt" to
"Operation failed" for a number of issues not related to table
corruption. For example "Lock wait timeout exceeded" and
"Deadlock found trying to get lock".
Test cases added to merge.test and check.test.

"mysql_upgrade (ver 5.1) add 3 fields to mysql.proc table but does
not set values".
mysql_upgrade (ver 5.1) adds 3 fields (character_set_client,
collation_connection and db_collation) to the mysql.proc table, but
does not set any values. When we run stored procedures, which were
created with mysql 5.0, a warning is logged into the error log.
The solution to this is for mysql_upgrade to set default best guess
values for these fields. A warning is also written during upgrade, to
make the user aware that default values are set.

- rewrite "check warnings" to be faster by not creating a full join
between error_log and suspicious_patterns while running REGEXP.
Instead add a column to error_log that will be set to 1 to indicate
a warning and run the 6 REGEXP's we have for suspicious lines as
6 separate full table scans.
- Remove the "suspicious_patterns" table from mtr db
- Use 'xykls37' as separator when loading the error log, that line should
hopefully never exist in a line that should be a warning

Problem: during a refactoring of mtr, a pattern for suppressing a warning from lowercase_table3 was lost.
Fix: re-introduce the suppression.
Problem 2: suppression was misspelt as supression. Fixed by adding a p.

- Improve mysql_upgrade and add comments describing it's logic
- Don't look for mysql and mysqlcheck randomly, use dir where mysql_upgrade
was started from
- Don't look for mysql_fix_privilege_tables.sql randomly, compile
in the mysql_fix_privilege_tables.sql file and use that to upgrade
the system tables of MySQL
- Check for any unexpected error returned from runnning the mysql_fix_privilege_tables SQL
- Fix bug#26639, bug#24248 and bug#25405
