Analysis:
-------------------------------
According to the Manual
(http://dev.mysql.com/doc/refman/5.1/en/identifier-case-sensitivity.html):
"Column, index, stored routine, and event names are not case sensitive on any
platform, nor are column aliases."
In other words, 'lower_case_table_names' does not affect the behaviour of
those identifiers.
On the other hand, trigger names are case sensitive on some platforms,
and case insensitive on others. 'lower_case_table_names' does not affect
the behaviour of trigger names either.
The bug was that SHOW statements did case sensitive comparison
for stored procedure / stored function / event names.
Fix:
Modified the code so that comparison in case insensitive for routines
and events for "SHOW" operation.
As part of this commit, only fixing the test failures due to the actual code fix.
It includes speed optimizations for HANDLER READ by caching as much as possible in HANDLER OPEN
Other things:
- Added mysqld option --disable-thr-alarm to be able to benchmark things without thr_alarm
- Changed 'Locked' state to 'System lock' and 'Table lock' (these where used in the code but never shown to end user)
- Better error message if mysql_install_db.sh fails
- Moved handler function prototypes to sql_handler.h
- Remove not anymore used 'thd->locked' member
include/thr_alarm.h:
Added my_disable_thr_alarm
include/thr_lock.h:
Add new member to THR_LOCK_DATA to remember original lock type state. This is needed as thr_unlock() resets type to TL_UNLOCK.

sql/Makefile.am:
Added sql_handler.h
sql/lock.cc:
Split functions to allow one to cache value if store_lock() (for HANDLER functions).
- Split mysql_lock_tables() into two functions, where first one allocates MYSQL_LOCK and other other one uses it.
- Made get_lock_data() an external function.
- Added argument to mysql_unlock_tables() to not free sql_lock.
- Added argument to reset_lock_data() to reset lock structure to initial state (as after get_lock_data())

Rewrote mysql_ha_open() to cache all things from TABLE_LIST and items for field list, where etc.
In mysql_ha_open() also cache MYSQL_LOCK structure from get_lock_data().
Split functions into smaller sub functions (needed to be able to implement mysql_ha_read_prepare())
Added mysql_ha_read_prepare() to allow one to prepare HANDLER READ.

mysql-test/r/func_misc.result:
Move test that requires query cache from main.func_misc to main.query_cache.
mysql-test/r/mysqltest.result:
Fix test failure due to race.
This test case creates > 300 connections in a tight loop, and depending on thread
scheduling and load, even though each connection is immediately disconnected
before connecting the next one, the server max connections may still be exceeded
due to server not being able to free old connections as fast as new ones are made.
mysql-test/r/query_cache.result:
Move test that requires query cache from main.func_misc to main.query_cache.

mysql-test/suite/funcs_1/datadict/processlist_val.inc:
Fix race where result file may show state "cleaning up" in the small window
between setting COMMAND to 'Sleep' and clearing STATE.
mysql-test/suite/rpl/r/rpl_temporary.result:
Fix race with suppression of warning message by fixing the test to not generate the
warning message in the first place.
Problem was a race between creating an anonymous account and resetting the slave.
If the slave reset happens before replicating the account, the subsequest deletion
of the account will fail to replicate correctly due to missing row.
mysql-test/suite/rpl/t/rpl_temporary.test:
Fix race with suppression of warning message by fixing the test to not generate the

Problem was a race between creating an anonymous account and resetting the slave.

mysql-test/t/variables.test:
Move test that requires query cache from main.variables to main.query_cache.
tests/mysql_client_test.c:
In tests that require query cache, skip the test if query cache not available.
Do this dynamically rather than using HAVE_QUERY_CACHE, as there is no guarantee
that the server we run against was compiled with same preprocessor #define as
the mysql_client_test program (and since it is trivial to check dynamically).
hide_view_error() does not take into account that thread query may be killed.
Added a check for thd->killed.

an assertion in a debug build.
The reason is that the C API doesn't support multiple result sets for prepared
statements and attempting to execute a stored routine which returns multiple result
sets sometimes lead to a network error. The network error sets the diagnostic area
prematurely which later leads to the assert when an attempt is made to set a second
server state.
This patch fixes the issue by changing the scope of the error code returned by
sp_instr_stmt::execute() to include any error which happened during the execution.
To assure that Diagnostic_area::is_sent really mean that the message was sent all
network related functions are checked for return status.

+ Fix for Bug#43114 wait_until_count_sessions too restrictive, random PB failures
+ Removal of a lot of other weaknesses found
+ modifications according to review
The problem is that since MyISAM's concurrent_insert is on by
default some concurrent SELECT statements might not see changes
made by INSERT statements in other connections, even if the
INSERT statement has returned.
The solution is to disable concurrent_insert so that INSERT
statements returns after the data is actually visible to other
statements.

Disable and restore concurrent_insert value at the end of the
test case. The test case for Bug 29936 requires that the inserted
rows need to be visible before a SELECT statement is queued in
another connection.
Remove sleep at the start of the test, it's not necessary to log
the result of the processlist command, showing the warnings has
the same end result.
