  Update key lengths in EXPLAIN to reflect true VARCHARs

  Fix bug: InnoDB created all indexes on true VARCHARs as column prefix keys because field->pack_length() for a true VARCHAR is bigger than key_part->length; FOREIGN KEYs could not be created on true VARCHARs then

  Fix a crash in a simple search with a key: the dtype->len of a true VARCHAR is the payload maximum len in bytes: it does not include the 2 bytes MySQL uses to store the string length

DATA_VARMYSQL so remove unnecessary condition.

The idea is to use TABLE_LIST::lock_type for passing type of lock for
target table to mysql_load() instead of using LEX::lock_option 
(which were rewritten by first subselect in SET clause).

This should also fix potential problem with LOAD DATA in SP
(it is important for them to have right lock_type in the table
 list by the end of statement parsing).

  Check that there is a disabled.def before using it
disabled.def:
  Reenable ndb tests accidently disabled

  calc_row_difference(): Use non-inlined functions to avoid linking error.

Now one can use user variables as target for data loaded from file
(besides table's columns). Also LOAD DATA got new SET-clause in which
one can specify values for table columns as expressions.

For example the following is possible:
LOAD DATA INFILE 'words.dat' INTO TABLE t1 (a, @b) SET c = @b + 1;

This patch also implements new way of replicating LOAD DATA.
Now we do it similarly to other queries.
We store LOAD DATA query in new Execute_load_query event
(which is last in the sequence of events representing LOAD DATA).
When we are executing this event we simply rewrite part of query which
holds name of file (we use name of temporary file) and then execute it
as usual query. In the beggining of this sequence we use Begin_load_query
event which is almost identical to Append_file event

Alter RPM to include mysqlmanger binary and config files.

  Added feature to disable tests from a list in a file "disabled.def"
  Moved down the code that disables, so that --do-test and --start-from
  don't list the disabled tests not in range.

This is a modifiction of my previous patch after receiving feedback. This is a better way to fix the problem.  With this patch, data directory and index directory will use only forward slashes (/) when on Windows.

mysqldump.c:
  Removed fixPaths routine.  Was improper fix for bug #6660
sql_show.cc:
  Changed append_directory to convert backslashes to foward slashes when on Windows.

    define _XOPEN_SOURCE=500 for solaris

-This is mostly fixes for correct behaviour when using query cache + transactions + the thread that
fetches commit count from NDB at regular intervals. The major fix is to add a
list in thd_ndb, that keeps a list of NDB_SHARE's that were modified by
transaction and then "clearing" them in ndbcluster_commit.
