  Bug#48351 Inconsistent library names for semisync plugin
  
  The semisync plugin library names on Unix like systems were prefixed with
  'lib', which did not follow the conventions.
  
  Fix the problem by removing the 'lib' prefix on Unix systems.

from mysql-next-mr-bugfixing into mysql-trunk-bugfixing.

NOTE: the "utf8_phone_ci" collation does not exist in mysql-trunk yet,
so another collation with 2-byte collation ID is used: "utf8_test_ci".

This patch will be null-merged to mysql-next-mr-bugfixing.

  Bug#47756 Setting 2byte collation ID with 'set names' crashes the server
  
  The problem is not actually related to 2byte collation IDs.
  The same crash happens if you change the collation ID in
  mysql-test/str_data/Index.xml to a value smaller than 256.
  
  Crash happened in SQL parser, because the "ident_map" and "state_map"
  arrays were not initialized in loadable utf8 collations.
  
  Fix: adding proper initialization of the "ident_map" and "state_map"
  members for loadable utf8 collations.
------------------------------------------------------------

Fix for bug#46117: This test is replaced by plugin.test also containing a CRESTE TABLE on example db. Example DB only exists as plugin. 

WL#3951 - MyISAM: Additional Error Logs for Data Corruption
Fixed partition_repair_myisam.test.

mysql-test/suite/parts/t/partition_repair_myisam.test:
  Suppress some extra warnings produced by MyISAM.

Bug#35591 FLUSH PRIVILEGES caused a crash

A race condition on the privilege hash tables (proc_priv_hash
and func_priv_hash) caused one thread to try to delete elements
that had already been deleted by another thread.

The bug was caused by reading and saving the pointers to 
the hash tables outside mutex protection.  This led to an
inconsistency where a thread copied a pointer to a hash,
another thread did the same, the first thread then deleted
the hash, and the second then crashed when it in turn tried to
delete the deleted hash.

The fix is to ensure that operations on the shared hash structures
happens under mutex protection (moving the locking up a little)

Implemented a new INFORMATION_SCHEMA table, which is intended to
provide information about tablespaces.

mysql-test/r/information_schema.result:
  Updated test result according to WL#2511. With this WL
  I_S has new TABLESPACES schema.
mysql-test/r/information_schema_db.result:
  Updated test result according to WL#2511. With this WL
  I_S has new TABLESPACES schema.
mysql-test/r/mysqlshow.result:
  Updated test result according to WL#2511. With this WL
  I_S has new TABLESPACES schema.
mysql-test/suite/funcs_1/r/is_columns_is.result:
  Updated test result according to WL#2511. With this WL
  I_S has new TABLESPACES schema.
mysql-test/suite/funcs_1/r/is_tables_is.result:
  Updated test result according to WL#2511. With this WL
  I_S has new TABLESPACES schema.
sql/handler.h:
  Added SCH_TABLESPACES to enum_schema_tables.
sql/mysql_priv.h:
  Added human readable definitions for I_S.TABLESPACES field
  identifiers.
sql/sql_show.cc:
  Added I_S.TABLESPACES schema. The code which handles I_S.FILES
  is capable to handle I_S.TABLESPACES as well. Thus we reuse
  this code and let functions/variables have more generic names.

The problem is not actually related to 2byte collation IDs.
The same crash happens if you change the collation ID in
mysql-test/str_data/Index.xml to a value smaller than 256.

Crash happened in SQL parser, because the "ident_map" and "state_map"
arrays were not initialized in loadable utf8 collations.

Fix: adding proper initialization of the "ident_map" and "state_map"
members for loadable utf8 collations.
