State of MERGE between MariaDB 5.5 and MySQL 5.6.5-m8

Featured copied/merged
- storage/innodb/*
- storage/perfschema
- sql/share/errmsg-utf8.txt
- mysqltest/suite/perfschema
- All CF_XXX states in sql_class.h.
- handler error messages.
- Removed timestamp handling from all handler::write and handler::update
  methods.
- Added PSI_CALLS to handler.cc
- Added thd->m_statement_psi
- Added variables Sys_ssl_crl & Sys_ssl_crlpath
  (Including support in all clients)
- Added Ssl_server_not_before & Ssl_server_not_after variables
  (Including changes to yassl)
- Added all mysql systems tables
- TRANSACTION READ ONLY | READ WRITE

Features recoded
- Better error messages
- Added support of timestamps to ha_write and ha_update.

Fetures half done:
- CF_XXX states added to init_update_queries() but not otherwise used.

Short time TODO:
- Add test cases for InnoDB

- merge hostname.cc / hostname.h
- add support for host_error()
- Enable performance_schema.host_cache in scripts/mysql_system_tables.sql

- Add Sys_my_bind_addr(); Needed for perfschema

- Add support for format_section_buff in unireg.cc and table.cc

- mysql_socket_shutdown() was removed from vio/viosocket.cc.
  It was replaced with inline function in include/mysql/psi/mysql_socket.h
  but this doesn't call DisconnectEx(). We should check if we need to
  add this to the inline function...

  why --source include/have_innodb.inc in lots of tests? (with no other changes)
  Sys_var_tx_read_only not needed (must be the same as Sys_var_tx_isolation)
  SIGNAL/RESIGNAL ?
  fix mysql-test to know the difference between compiled-in innodb and compiled-in xtradb
  remove my_getopt_use_args_separator
