Bug #57551: Live upgrade fails between 5.1.52 -> 5.5.7-rc

Browse Source 
Updated the server to treat a missing mysql.proxies_priv table 
as empty. 
Added some grants to make sure tables are correctly opened
when they must be opened.
Fixed a mysql_upgrade omission not adding rights to root to 
execute GRANT PROXY on other users.
Removed a redundant CREATE TABLE from 
mysql_system_tables_fix.sql since it's always executed after
mysql_system_tables.sql and the first file has CREATE TABLE 
in it. 
Added a test case for the above.
Fixed error handling code to close the cursor
