Miscellaneous workarounds for  drop-in compatibility problems with Linux distributions, arounf versioning of the 
MySQL 5.5 client shared library. There seems to be 3 different ways major distributions handle versioning

1. Fedora  (also Mageia, and likely  other Redhat descendants) way 
   old, 5.1 API functions are given version libmysqlclient_16
   new API functions  (client plugins, mysql_stmt_next ) are given version libmysqlclient_18
   some extra functions beyond API are exported.
   some functions are renamed.

2.Debian Wheezy way 
  all functions are given libmysqlclient_18 version

3. Ubuntu  way (or MySQL/MariaDB download packages)
  no versioning

UIp to this fix, MariaDB distributions did not have any versioning in the libraries, this rendered client library incompatible to distributions 
thus exchanging  distribution's libmysqlclient.so.18.0.0  with MariaDB's did not work nicely (anywhere but on Ubuntu)


THE FIX  
is to build libraries the same way as distributions do it 
- when building RPMs, use  same version script as Fedora does, Make sure to export extra-symbols, the same as Fedora exports.
- when building DEBs, use the same version script as Debian Wheezy
- do not use version scripts otherwise


Also, makes sure that extensions of  MySQL APIs (asynchronous client functionality) is exported by  the shared libraries.

FIx  : make "shared" RPM obsolete/provide mysql-libs

test suite added.

MDEV-3952 Incompatible change in MariaDB-5.5.28a-client rpm adds mytop when not in MariaDB-5.5.23-client (CentOS 5)

Same as for deb: don't add mytop to the client rpm.

MDEV-3934 Assertion `((keypart_map+1) & keypart_map) == 0' failed in _mi_pack_key with an index on a POINT column

sel_arg_range_seq_next(): set keypart map also for GEOM_FLAG keys

MDEV-4029 SELECT on information_schema using a subquery locks up the information_schema table due to incorrect mutexes handling

Early evaluation of subqueries in the WHERE conditions on I_S.*_STATUS tables,
otherwise the subquery on this same table will try to acquire LOCK_status twice.

sql/item.h:
  remove unused method

MDEV-3832 MariaDB conflicts with packages filesystem-3.1-2.fc18.i686 and jre-1.7.0_09-fcs.i586 on Fedora 18

fix the rpm packaging to work on Fedora18. Two problems:
* conflicts on common directories with other packages.
* more auto-generated requirements for mariadb-test.rpm

initialize cache_mngr and write the Xid into binlog even
if binlog is disabled with SQL_LOG_BIN=0 or no --log-slave-updates
in the slave thread

Add a test case.
The fix comes with MySQL bug#15948123: SERVER WORKS INCORRECT WITH LONG TABLE ALIASES

Fix Windows installers' bootstrapper scripts ,  after mysql_performance_tables.sql was  split off mysql_system_tables.sql

This fixed failing test in group_by.test

  Updated test case
mysql-test/r/join_outer_jcl6.result:
  Updated test case
sql/item.cc:
  Don't reset maybe_null in update_used_tables(); This breaks ROLLUP
sql/item.h:
  Don't reset maybe_null in update_used_tables(); This breaks ROLLUP
sql/item_cmpfunc.h:
  Don't reset maybe_null in update_used_tables(); This breaks ROLLUP

(because it's conceptually wrong. only the user can decide whether the kill is
allowed to leave tables in the inconsistent state, storage engine has no say in that)

The previous fix for MDEV-3992 was incomplete, because it still computed
incorrectly the number of keyparts of the extended secondary key in the
case when columns of the PK participate in the secondary key.

This patch by Monty corrects the above problem.

Analysis:
  The crash is a result of incorrect analysis of whether a secondary key
  can be extended with a primary in order to compute ORDER BY. The analysis
  is done in test_if_order_by_key(). This function doesn't take into account
  that the primary key may in fact index the same columns as the secondary
  key. For the test query test_if_order_by_key says that there is an extended
  key with total 2 keyparts.
  At the same time, the condition
    if (pkinfo->key_part[i].field->key_start.is_set(nr))
  in test_if_cheaper_oredring() becomes true for (i == 0), which results in
  an invalid access to rec_per_key[-1].
  
Solution:
  The best solution would be to reuse KEY::ext_key_parts that is already computed
  by open_binary_frm(), however after detailed analysis the conclusion is that
  the change would be too intrusive for a GA release.
  The solution for 5.5 is to add a guard for the case when the 0-th key part is
  considered, and to assume that all keys will be scanned in this case.
