Transcode the procedure name to lowercase when searching for it in the 
hash. This is the missing part of the fix for bug #41049.

There was an error in an internal structure in the range
optimizer (SEL_ARG). Bad design causes parts of a data
structure not to be initialized when it is in a certain
state. All client code must check that this state is not
present before trying to access the structure's data. Fixed
by

- Checking the state before trying to access data (in
several places, most of which not covered by test case.)

- Copying the keypart id when cloning SEL_ARGs

BUG#46000 - using index called GEN_CLUST_INDEX crashes server

Detailed revision comments:

r6180 | jyang | 2009-11-17 10:54:57 +0200 (Tue, 17 Nov 2009) | 7 lines
branches/5.0: Merge/Port fix for bug #46000 from branches/5.1
-r5895 to branches/5.0. Disallow creating index with the
name of "GEN_CLUST_INDEX" which is reserved for the default
system primary index. Minor adjusts on table name screening
format for added tests.

Arg_comparator now takes into account that some of
optimizations aren't done in the PREPARE stmt.

BUG#47777 - innodb dies with spatial pk: Failing assertion: buf <= original_buf + buf_len

to bracnches/5.0. Treat the Geometry data same as Binary BLOB

data is stored as Binary BLOB in Innodb.

mysql client displays wrong character-set of server. When a user changes the
charset of a server, mysql client 'status' command displays wrong charset but
the command "SHOW VARIABLES LIKE "%charset%" displayed correct charset results.
The problem is only with the mysql client's 'status' command output.

In mysql client, the method mysql_store_lazy_result() returns 0 for
success and non-zero for failure. The method com_status() was using this method
wrongly. Fixed all such instances according to return value of the method 
mysql_store_lazy_result().

Testing for presence of stuff in a hash inside the function
that's filling in the hash creates chicken-and-egg type of problems.
This results in test suite failures in mysql-pe in debug mode and 
adds bad initialization dependency in 5.1.
Fixed by removing the debug code.

In RBR, All statements operating on temporary tables should not be binlogged.
Despite this fact, after executing 'TRUNCATE... ' on a temporary table, 
the command is still logged, even if in row-based mode. Consequently, this raises
problems in the slave as the table may not exist, resulting in an
execution failure. Ultimately, this causes the slave to report
an error and abort.

After this patch, 'TRUNCATE ...' statement on a temporary table will not be
binlogged in RBR.

The problem is that the server could crash when attempting
to access a non-conformant proc system table. One such case
was a crash when invoking stored procedure related statements
on a 5.1 server with a proc system table in the 5.0 format.

The solution is to validate the proc system table format
before attempts to access it are made. If the table is not
in the format that the server expects, a message is written
to the error log and the statement that caused the table to
be accessed fails.
