rows was different in embedded and non-embedded version. So the only
way to fix this is to add an ORDER BY clause.

Improve the range estimation algorithm.

Previously:
For a given level the algo knows the number of pages in the requested range
and the number of records on the leftmost and the rightmost page. Then it
assumes all pages in between contain the average between the two border pages
and multiplies this average number by the number of intermediate pages.

With this change:
Same idea, but peek a few (10) of the intermediate pages to get a better
estimate of the average number of records per page. If there are less than 10
intermediate pages then all of them will be scanned and the result will be
precise, not an estimation.

In the bug report one of the examples has a btree with a snippet of the leaf
level like this:
page1(899 records), page2(1 record), page3(1 record), page4(1 record)
so when trying to estimate, the previous algo, assumed there are average
(899+1)/2=450 records per page which went terribly wrong. With this change
page2 and page3 will be read and the exact number of records will be returned.

NDB supports only a limited set of item nodes for use in engine condition
pushdown. Because of this adding cache for const expression effectively
disabled this optimization.
      
The ndb_serialize_cond function is extended to support Item_cache and treat
it as a constant values.
A helper function called ndb_serialize_const is added. It is used to create
Ndb_cond value node from given const item.

           corruption on ADD PARTITION and LOCK TABLE
Bug#53770: Server crash at handler.cc:2076 on
           LOAD DATA after timed out COALESCE PARTITION

5.5 fix for:
Bug#51042: REORGANIZE PARTITION can leave table in an
           inconsistent state in case of crash
Needs to be back-ported to 5.1

5.5 fix for:
Bug#50418: DROP PARTITION does not interact with
           transactions

Main problem was non-persistent operations done
before meta-data lock was taken (53770+53676).
And 53676 needed to keep the table/partitions opened and locked
while copying the data to the new partitions.

Also added thorough tests to spot some additional bugs
in the ddl_log code, which could result in bad state
between the .frm and partitions.

Collapsed patch, includes all fixes required from the reviewers.

  "MySQL server is not restarted properly after RPM upgrade"

The problem is that with the general spec file cleanup and
alignment we also did a name change, dropping the "-community"
part from the package file name.

As a result of this, RPM (some versions of it) will report
file conflicts, because it considers this name difference
to imply different packages.
To avoid this, the spec file explicitly "obsoletes" the old
packages (with "-community" in the file name).

Now, RPM will first install these packages and the remove the
old ones, and part of that removal is running the "%preun"
section which stops the server and uninstalls the service
(removes the symlinks to "/etc/init.d/mysql" from the run
level directories).
This stop/uninstall will affect the new server!

The fix is to define a "%triggerpostun" in this spec file
which will watch for removal of the "-community" server.
If this is done (as part of this install/upgrade), the
trigger code will re-install the service and restart the
server process.

In addition, the "sleep" calls after starting the server
have been cleaned up: Rather than doing 2* "sleep 2",
it is now 1 "sleep 5".

it couldn't parse the --ssl option.

client/mysql_upgrade.c:
  mysql_upgrade parses its options and passes some of them to the underlying
  tools (mysqlcheck etc). To do this passdown, it reconstructs a
  command-line-suitable text from the my_option object (which
  contains the option's name and option's value). For options
  which expect no parameter, it just had to use the option's name;
  for other options, it had to concatenate the option's name,
  a "=" symbol, and the option's value; it had code to handle
  this latter case, but only for GET_STR options (options taking a
  string as value). But since the work on WL 4738, the --ssl
  option, a GET_BOOL, which used to have no parameter (NO_ARG), can
  now have one (OPT_ARG), so with --ssl we came to the "default"
  label, error. Fixed by constructing the command-line-suitable
  representation for GET_BOOL too. For --ssl it will produce
  --ssl=1 ; for --ssl=0, it will produce --ssl=0.
mysql-test/include/mysql_upgrade_preparation.inc:
  handles requirements of tests which use mysql_upgrade
mysql-test/r/mysql_upgrade_ssl.result:
  result; without the code fix we would get "internal error".
mysql-test/t/mysql_upgrade.test:
  This test has requirements before running; moved them
  to an include file in order to share with mysql_upgrade_ssl.
mysql-test/t/mysql_upgrade_ssl.test:
  test for bug. Couldn't go into mysql_upgrade.test as this new test requires
  SSL support. --force is needed, in case mysql_upgrade.test run before
  (in which case mysql_upgrade_ssl would say that upgrade has already been
  done); --force forces the upgrade in all cases.

This is a performance improvement fix.

Removed the "volatile" property of PFS_events_waits::m_wait_class.
Simplified the code accordingly.

The test for bug no 50939 was put in range.test which isn't such a good idea
since it requires partitioning. Fixed by moving the test case to
partitioning_range.test.
