Pre push fix, optimized replace_regex, to cut 2 seconds
from test time.

tables can cause server to crash!

The bug will be fixed by patch for #34779: "crash in checksum table
on federated tables with blobs containing nulls"

Only a test case commited.


mysql-test/r/federated.result:
  Test case for bug #34774: key prefix on text field in federated 
  tables can cause server to crash!
    - test result.
mysql-test/t/federated.test:

  tables can cause server to crash!

when InnoDB frm file corruption

Problem: mysqlcheck runs 'SHOW FULL TABLE' queries to get table lists.
The query may fail for some reasons (e.g. null .frm file) then
mysqlcheck doesn't process the database tables.

Fix: try to run 'SHOW TABLES' if 'SHOW FULL TABLES' failed.


client/mysqlcheck.c:
  Fix for bug#37527: mysqlcheck fails to report entire database 
  when InnoDB frm file corruption
    - run "SHOW TABLES" query if "SHOW /*!50002 FULL*/ TABLES" failed;
    - print error info if both failed.
mysql-test/r/mysqlcheck.result:
  Fix for bug#37527: mysqlcheck fails to report entire database 
  when InnoDB frm file corruption
    - test result.
mysql-test/t/mysqlcheck.test:
  Fix for bug#37527: mysqlcheck fails to report entire database 
  when InnoDB frm file corruption
    - test case.

Reordered include files so that no mess will be left if this test is run without InnoDB
Previously, this test would leave a database named 'federated' in such a case and would
cause tests that examined existing databases to fail.

VARIABLE_VALUE field is decreased to 1024 symbols.
(affected I_S tables: GLOBAL_VARIABLES, SESSION_VARIABLES,

The only variable which can be longer than 1024 is
init_connect. The variable will be truncated with warning.
Additional fix:
Added where condition filter which speed up queries which

mysql_config did not output -ldl (or equivalent) when needed for --libmysqld-libs,
so its output could be insufficient to build an application using the embedded
server.

LIBDL was already set in configure; it's now propagated all the way into the
relevant mysql_config scripts.

scripts/Makefile.am:
  We "manually" replace configure's constants in .sh scripts using sed,
  so AC_SUBST() alone is not good enough. Add LIBDL to the substitution
  list; we'll be needing it for mysql_config --libmysqld-libs
scripts/mysql_config.pl.in:
  Add LIBDL (usually -ldl) to output of mysql_config --libmysqld-libs (perl version)
scripts/mysql_config.sh:
  Add LIBDL (usually -ldl) to output of mysql_config --libmysqld-libs (shell version)

japanese characters.

Fix - removed obsolvete setlocale from my_init.c . In MBCS 
environments it caused unwanted character-to-byte translations
in fputc()  in client code and wrong output as result.

on tables with partitions

Problem was that the handler function try_semi_consistent_read
was not propagated to the innodb handler.

Solution was to implement that function in the partitioning
handler.

mysql-test/r/partition_innodb.result:
  Bug#40595: Non-matching rows not released with READ-COMMITTED
  on tables with partitions
  
  Updated test result.
mysql-test/t/partition_innodb.test:
  Bug#40595: Non-matching rows not released with READ-COMMITTED
  on tables with partitions
  
  Added test case for bug#40595.
  
  Note: the replace_regex is taking long time. I have not found
  any better regex (it takes time using 'sed' too).
sql/ha_partition.cc:
  Bug#40595: Non-matching rows not released with READ-COMMITTED
  on tables with partitions
  
  Added function to the partitioning handler for handling
  semi consistent reads (unlock_row was already implemented,
  and this is needed for unlock_row to work properly in innodb).
  It uses pruning for optimizing the call.
sql/ha_partition.h:
  Bug#40595: Non-matching rows not released with READ-COMMITTED
  on tables with partitions
  
  Added function to the partitioning handler for handling
  semi consistent reads (unlock_row was already implemented,
  and this is needed for unlock_row to work properly in innodb).

            
Innodb monitor could cause a server crash because of invalid access to a
shared variable in a concurrent environment.
                  
This patch adds a guard to protect against crashes but not against
inconsistent values because of performance reasons.

  * Attempt snapshot of static memory pointer proc_info to avoid null pointers.

Problem 1: BUG#36625: rpl_redirect doesn't do anything useful. It tests an
obsolete feature that was never fully implemented.
Fix 1: Remove rpl_redirect.
Problem 2: rpl_innodb_bug28430 and rpl_flushlog_loop are disabled despite the
bugs for which they were disabled have been fixed.
Fix 2: Re-enable rpl_innodb_bug28430 and rpl_flushlog_loop.
