Instead of just filtering space, filter white space (\s)
I left the default.experimental file as is, with tabs.

Fix for --vs-config applied
Find.pm incorrectly tested an unitialized local variable instead
  of the global, corrected.
Find.pm is also wrong in 5.5: uses a non-existent global variable. Fix when
  merging up.

Changed to use $bindir instead of $basedir
Simplified search for files: find all *.gcno
Also, .msg and .err files had been mixed up

               PRIMARY KEY NO 0 FOR TABLE IN ERROR LOG 

Post merge fix, update the .result file.

Forgot that the main thread would be idle while waiting for tests
Added sub mark_time_idle() so ignore time spent waiting
Also added a new time category 'admin' to take some of 'init'

Added necessary options and variables
Added dbx_arguments() similar to gdb_arguments()
Unlike gdb, cannot use init file but must provide commands and args as
  command line argument to dbx
Also simplified debugger behavior to always start with a breakpoint in main()

There was a local variable in get_all_tables() to store the 
"original" value of the database name as it can get lowercased
depending on the lower_case_table_name value.
get_all_tables() iterates over database names and for each 
database iterates over the tables in it.
The "original" db name was assigned in the table names loop.
Thus the first table is ok, but the second and subsequent tables
get the lowercased name from processing the first table.
Fixed by moving the assignment of the original database name
from the inner (table name) to the outer (database name) loop.
Test suite added.

In the string context the MIN() and MAX() functions don't take
into account the unsignedness of the UNSIGNED BIGINT argument
column.

I.e.:
        CREATE TABLE t1 (a BIGINT UNSIGNED);
        INSERT INTO t1 VALUES (18446668621106209655);
        SELECT CONCAT(MAX(a)) FROM t1;

returns -75452603341961.

  Bug #11766094 - 59132: MIN() AND MAX() REMOVE UNSIGNEDNESS
  
  The Item_cache_int::val_str() method has been modified to
  take into account the unsigned_flag value when converting
  data to string.

Bug #11936829: DIFF. BETWEEN MYSQL.USER (AUTHENTICATION_STRING) IN 
  FRESH AND UPGRADED 5.5.11
             
There was no modification for pre 5.5.11 builds that had 
authentication_string.  Thus the column was not upgraded 
by mysql_upgrade.
                         
Fixed by adding an ALTER TABLE MODIFY to update an existing 
column to the latest type version.
                                     
Test suite added.

The patch fixes a build problem on MacOSX, where
the compiler complains about unused parameters.

sync_array_print_long_waits(): Return the longest waiting thread ID
and the longest waited-for lock. Only if those remain unchanged
between calls in srv_error_monitor_thread(), increment
fatal_cnt. Otherwise, reset fatal_cnt.

Background: There is a built-in watchdog in InnoDB whose purpose is to
kill the server when some thread is stuck waiting for a mutex or
rw-lock. Before this fix, the logic was flawed.

The function sync_array_print_long_waits() returns TRUE if it finds a
lock wait that exceeds 10 minutes (srv_fatal_semaphore_wait_threshold).
The function srv_error_monitor_thread() will kill the server if this
happens 10 times in a row (fatal_cnt reaches 10), checked every 30
seconds. This is wrong, because this situation does not mean that the
server is hung. If the server is very busy for a little over 15
minutes, it will be killed.

Consider this example. Thread T1 is waiting for mutex M. Some time
later, threads T2..Tn start waiting for the same mutex M. If T1 keeps
waiting for 600 seconds, fatal_cnt will be incremented to 1. So far,
so good. Now, if M is granted to T1, the server was obviously not
stuck. But, T2..Tn keeps waiting, and their wait time will be longer
than 600 seconds. If 5 minutes later, some Tn has still been waiting
for more than 10 minutes for the mutex M, the server can be killed,
even though it is not stuck.

Valgrind warning happens due to missing NULL value check in
Item::get_date. The fix is to add this check.


mysql-test/r/func_time.result:
  test case
mysql-test/t/func_time.test:
  test case
sql/item.cc:
  added check for NULL value

Valgrind warning happens because null values check happens too late
in Item_func_month::val_str(after result string calculation).The fix
is to check null value before result string calculation.

sql/item_timefunc.h:
  check null value before result string calculation.

The LGPL license is used in some legacy code, and to
adhere to current licensing polity, we remove those
files that are no longer used, and reorganize the
remaining LGPL code so it will be GPL licensed from
now on.
            
Note:  This patch only removed LGPL licensed files
       in MySQL 5.5 and later, and is the third of a 
       set of patches to remove LGPL from all trees.
