Addendum fixes after changing the condition variable
for the global read lock.

The stress test suite revealed some deadlocks. Some were
related to the new condition variable (COND_global_read_lock)
and some were general problems with the global read lock.

It is now necessary to signal COND_global_read_lock whenever 
COND_refresh is signalled.

We need to wait for the release of a global read lock if one 
is set before every operation that requires a write lock.
But we must not wait if we have locked tables by LOCK TABLES.
After setting a global read lock a thread waits until all
write locks are released.

Sometimes the helper connection (that is watching for the main connection
to time out) would itself time out first, causing the test to fail.

  Increase connection timeout in connection wait_con so we will not loose
  the connection that is watching for the real wait_timeout to trigger.

  Check for FN_DEVCHAR in the table name just before file creation. This allows for temporary tables to contain FN_DEVCHAR in the name.
sql/table.cc:
  Removed the check for FN_DEVCHAR is done at this level because it prevents Windows from creating any table with FN_DEVCHAR in the name.

  An UNIQUE KEY consisting of NOT NULL columns
  was displayed as PRIMARY KEY in "DESC t1".
  According to the code, that was intentional
  behaviour for some reasons unknown to me.
  This code was written before bitkeeper time,
  so I cannot check who and why made this.
  After discussing on dev-public, a decision
  was made to remove this code

 with PREPARE fails with weird error".
More generally, re-executing a stored procedure with a complex SP cursor query
could lead to a crash.

The cause of the problem was that SP cursor queries were not optimized 
properly at first execution: their parse tree belongs to sp_instr_cpush,
not sp_instr_copen, and thus the tree was tagged "EXECUTED" when the
cursor was declared, not when it was opened. This led to loss of optimization
transformations performed at first execution, as sp_instr_copen saw that the
query is already "EXECUTED" and therefore either not ran first-execution 
related blocks or wrongly rolled back the transformations caused by 
first-execution code.
The fix is to update the state of the parsed tree only when the tree is
executed, as opposed to when the instruction containing the tree is executed.
Assignment if i->state is moved to reset_lex_and_exec_core.

sql/sp_head.cc:

The problem was in redundant calls to strlen() in string functions,
where we may then return after checking only the small number of characters.

No test case is provided since it's a performance fix.


strings/ctype-mb.c:
  Do not use strlen() where arbitrary horizon of at least
  CHARSET_INFO::mbmaxlen character is sufficient.

This bug in Field_string::cmp resulted in a wrong comparison 
with keys in partial indexes over multi-byte character fields.
Given field a is declared as a varchar(16) collate utf8_unicode_ci
INDEX(a(4)) gives us an example of such an index.
  
Wrong key comparisons could lead to wrong result sets if 
the selected query execution plan used a range scan by 
a partial index over a utf8 character field.
This also caused wrong results in many other cases.
