than max_connections -- which results in user lockout.

The problem was that the variable thread_count that contains
the number of active threads was interpreted as a number of
active connections.

The fix is to introduce a new counter for active connections.

In cases when TRUNCATE was executed by invoking mysql_delete() rather
than by table recreation (for example, when TRUNCATE was issued on
InnoDB table with is referenced by foreign key) triggers were invoked.
In debug builds this also led to crash because of an assertion, which
assumes that some preliminary actions take place before trigger 
invocation, which doesn't happen in case of TRUNCATE.

The fix is not to execute triggers in mysql_delete() when this
function is used by TRUNCATE.

Disable test case for bug 29948, which is causing sporadically
failures in other tests inside mysql_client_test.

The initial value of free memory blocks in 0. When the query cache is enabled 
a new memory block gets allocated and is assigned number 1. The free memory
block is later split each time query cache memory is allocated for new blocks.
This means that the free memory block counter won't be reduced to zero when
the number of allocated blocks are zero, but rather one. To avoid confusion
this patch changes this behavior so that the free memory block counter is
reset to zero when the query cache is disabled.
Note that when the query cache is enabled and resized the free memory block
counter was still calculated correctly.

It's impossible to determine which test inside mysql_client_test
failed if the log file is overwritten by mysqltest when dumping
the test case results. Redirect mysql_client_test output to a
separate file.

READ_ONLY token was accidentally placed into wrong place
('ident' rule). The proper place is in the 'keyword_sp' rule.

The manual should be re-generated after this patch, because
the manual depends on the 'keyword_sp' rule.

Rename client_last_error to last_error and client_last_errno to last_errno
to not break connectors which use the internal net structure for error handling.

The problem is that passing anything other than a integer to a limit
clause in a prepared statement would fail. This limitation was introduced
to avoid replication problems (e.g: replicating the statement with a
string argument would cause a parse failure in the slave).

The solution is to convert arguments to the limit clause to a integer
value and use this converted value when persisting the query to the log.

Bug#34678 @@debug variable's incremental mode

The problem is that the per-thread debugging settings stack wasn't
being deallocated before the thread termination, leaking the stack
memory. The chosen solution is to push a new state if the current
is set to the initial settings and pop it (free) once the thread
finishes.
