WL 2826: Error handling of ALTER TABLE for partitioning

Browse Source 
Loads of review comments fixed
inactivate => deactivate
table log => ddl log
Commented on Error Inject Module added
Put various #defines into enums
Fixed abort_and_upgrade_lock, removed unnecessary parameter
Fixed mysqlish method intro's
Fixed warning statements
5.1.7 was released still with partition states in clear text

Fixed io_size bug
Fixed bug in open that TRUNCATED before reading :)
file_entry => file_entry_buf
Don't open DDL log until first write call to DDL log
handler_type => handler_name
no => num

ERROR INJECT MODULE:
--------------------
These macros are used to insert macros from the application code.
The event that activates those error injections can be activated
from SQL by using:
SET SESSION dbug=+d,code;
After the error has been injected, the macros will automatically
remove the debug code, thus similar to using:
SET SESSION dbug=-d,code
from SQL.
ERROR_INJECT_CRASH will inject a crash of the MySQL Server if code
is set when macro is called. ERROR_INJECT_CRASH can be used in
if-statements, it will always return FALSE unless of course it
crashes in which case it doesn't return at all.
ERROR_INJECT_ACTION will inject the action specified in the action
parameter of the macro, before performing the action the code will
be removed such that no more events occur. ERROR_INJECT_ACTION
can also be used in if-statements and always returns FALSE.
ERROR_INJECT can be used in a normal if-statement, where the action
part is performed in the if-block. The macro returns TRUE if the
error was activated and otherwise returns FALSE. If activated the
code is removed.
Sometimes it is necessary to perform error inject actions as a serie
of events. In this case one can use one variable on the THD object.
Thus one sets this value by using e.g. SET_ERROR_INJECT_VALUE(100).
Then one can later test for it by using ERROR_INJECT_CRASH_VALUE,
ERROR_INJECT_ACTION_VALUE and ERROR_INJECT_VALUE. This have the same
behaviour as the above described macros except that they use the
error inject value instead of a code used by DBUG macros.
