When setting AUTOCOMMIT=1 after starting a transaction, the binary log
did not commit the outstanding transaction. The reason was that the binary
log commit function saw the values of the new settings, deciding that there
were nothing to commit.
Fixed the problem by moving the implicit commit to before the thread option
flags were changed, so that the binary log sees the old values of the flags
instead of the values they will take after the statement.

Inconsistent behavior of session variable max_allowed_packet
(and net_buffer_length); only assignment to the global variable
has any effect, without this being obvious to the user.
The patch for Bug#22891 is backported to 5.0, making the two
session variables read-only. As this is a backport to GA
software, the error used when trying to assign to the read-
only variable is ER_UNKNOWN_ERROR. The error message is the
same as in 5.1+.
mysql-test/t/variables.test:
Tests are changed to account for the new semantics, and assignment to the read-only variables is added to test
the emission of the correct error message.
sql/set_var.cc:
Both max_allowed_packet and net_buffer_length are changed
to be of type sys_var_thd_ulong_session_readonly. ER_UNKNOWN_ERROR is used to indicate an attempt to assign
to an instance of a read-only variable.
sql/set_var.h:
Class sys_var_thd_ulong_session_readonly is added.

The global variable max_binlog_cache_size cannot be set more than 4GB on
32 bit systems, limiting transactions of all storage engines to 4G of changes.
The problem is max_binlog_cache_size is declared as ulong which is 4 bytes
on 32 bit and 8 bytes on 64 bit machines.
Fixed by using ulonglong for max_binlog_cache_size which is 8bytes on 32
and 64 bit machines.The range for max_binlog_cache_size on 32 bit and 64 bit
systems is 4096-18446744073709547520 bytes.

When binlog_format is STATEMENT and the statement is unsafe before,

The binlog_innodb test was sensitive to what tests ran before it. Now run
FLUSH STATUS before performing operations that need to be checked.
sys_var_thd_ulong::update() was improperly casting an option value from
ulonglong to ulong before comparing it to the max allowed value. On systems
where ulong and ulonglong are of different size, this caused values greater
than ULONG_MAX to wrap around (not be truncated to ULONG_MAX, which appears to
have been the intention of the original coder), and caused some checks to work
incorrectly. This wasn't generally visible to the user, because later checks
would prevent the wrapped-around value from being used. But it caused warning
messages to differ between 32- and 64-bit platforms. Fix is to just remove the
cast. Also added a DBUG_ASSERT to ensure that the value really is capped
properly before finally stuffing it into the ulong.

The SHOW VARIABLES LIKE .../SELECT @@/SELECT ... FROM INFORMATION_SCHEMA.VARIABLES

However the variables that are settable through command line will have a different

Several system variables did not behave like system variables should do.
When trying to SET them or use them in SELECT, they were reported as
"unknown system variable". But they appeared in SHOW VARIABLES.
This has been fixed by removing the "fixed_vars" array of variables
and integrating the variables into the normal system variables chain.
All of these variables do now behave as read-only global-only
variables. Trying to SET them tells they are read-only, trying to
SELECT the session value tells they are global only. Selecting the
global value works. It delivers the same value as SHOW VARIABLES.

sql/share/errmsg.txt:

The code to get read the value of a system variable was extracting its value
on PREPARE stage and was substituting the value (as a constant) into the parse tree.
Note that this must be a reversible transformation, i.e. it must be reversed before
each re-execution.
Unfortunately this cannot be reliably done using the current code, because there are
other non-reversible source tree transformations that can interfere with this
reversible transformation.
Fixed by not resolving the value at PREPARE, but at EXECUTE (as the rest of the
functions operate). Added a cache of the value (so that it's constant throughout
the execution of the query). Note that the cache also caches NULL values.
Updated an obsolete related test suite (variables-big) and the code to test the
result type of system variables (as per bug 74).
