WL#5151 was pushed.

Problem 1: Some old binlog events do not contain metadata. This
makes checking whether the field can be converted or not rather
impossible because one cannot compare, for instance, field sizes
from original table and target table.

Solution 1: When an event does not contain metadata, we will just
check if field types are equal and assume that original field
definition matched with the one in the target table.

Problem 2: There is a second fix, which involves lack of
information regarding maybe_null. This was causing a conditional
jump warning when creating a conversion table. 

Solution 2: We will just assume that all fields that need to be
in the conversion table may be null.

In auto-commit mode, updating both trx and non-trx tables (i.e. issuing a mixed
statement) causes the following sequence of events:

1 - "Flush trx changes" (MYSQL_BIN_LOG::write) - T1:
  1.1 - mutex_lock (&LOCK_log)
  1.2 - mutex_lock (&LOCK_prep_xids)
  1.3 - increase prepared_xids
  1.4 - mutex_unlock (&LOCK_prep_xids)
  1.5 - mutex_unlock (&LOCK_log)

2 - "Flush non-trx changes" (MYSQL_BIN_LOG::write) - T1:
  2.1 - mutex_lock (&LOCK_log)
  2.2 - mutex_unlock (&LOCK_log)

3. "unlog" - T1
  3.1 - mutex_lock (&LOCK_prep_xids)
  3.2 - decrease prepared xids
  3.3 - pthread_cond_signal(&COND_prep_xids);
  3.4 - mutex_unlock (&LOCK_prep_xids)

The "FLUSH logs" command produces the following sequence of events:

1 - "FLUSH logs" command (MYSQL_BIN_LOG::new_file_impl) - user thread:
  1.1 - mutex_lock (&LOCK_log)
  1.2 - mutex_lock (&LOCK_prep_xids)
  1.3 - while (prepared_xids)  pthread_cond_wait(..., &LOCK_prep_xids);
  1.4 - mutex_unlock (&LOCK_prep_xids)
  1.5 - mutex_unlock (&LOCK_log)

A deadlock will arise if T1 flushes the trx changes and thus increases
prepared_xids but before it is able to continue the execution and flush the
non-trx changes, an user thread calls the "FLUSH logs" command and wait that
the prepared_xids is decreased and gets to zero. However, T1 cannot proceed
with the call to "Flush non-trx changes" because it will block in the mutex
"LOCK_log" and by consequence cannot complete the execution and call the
unlog to decrease the prepared_xids.

To fix the problem, we ensure that the non-trx changes are always flushed
before the trx changes.

Note that if you call "Flush non-trx changes" and a concurrent "FLUSH logs" is
issued, the "Flush non-trx changes" may block, but a deadlock will never happen
because the prepared_xids will eventually get to zero. Bottom line, there will
not be any transaction able to increase the prepared_xids because they will
block in the mutex "LOCK_log" (MYSQL_BIN_LOG::write) and those that increased
the prepared_xids will eventually commit and decrease the prepared_xids.

This fixes two more warnings for tests: 
  - rpl_row_colSize
  - rpl_typeconv

Metadata for geometric fields was not being properly stored by
the slave in its the table definition. This happened because
MYSQL_TYPE_GEOMETRY was not included in the 'switch... case' that
handles field metadata according to the field type. Therefore, it
would default to 0, leading to always have a mismatch between
master's field and slave fields'. 

We fix this by deploying the missing 'case MYSQL_TYPE_GEOMETRY:'.

mysql-test/extra/rpl_tests/type_conversions.test:
  Added some tests for blob fields and also the particular
  case for replicating from/into BLOB into/from GEOMETRY.
sql/field.h:
  As requested by Mats, reverted function added by him in
  changeset:

When @@session.binlog_format is modified inside a transaction,
it can cause slave to go out of sync.
      
To fix the problem, make the session variable 'binlog_format' 
read-only inside a transaction.


mysql-test/suite/binlog/r/binlog_format_switch_inside_trans.result:
  Test result for bug#47863.
mysql-test/suite/binlog/t/binlog_format_switch_inside_trans.test:
  Added test file to verify if the session variable 'binlog_format' 
  is read-only inside a transaction and in sub-statements.
sql/set_var.cc:
  Added code to make the session variable 'binlog_format'
  read-only inside a transaction.

This patch fixes these warnings and some compile time warnings.

On top of that, it also fixes rpl_err_ignoredtable test failure.
This test was failing because the warning suppression text was not
matching the latest text. We fix this by making them match.


mysql-test/suite/rpl/t/rpl_err_ignoredtable.test:
  Replaced the suppression text.
sql/rpl_record.cc:
  - Fixed some compile time warnings (replaced %d --> %ld and 
    removed unused mas mask variable.
  - Fixed valgrind warnings when using c_ptr(). Replaced with 
    c_ptr_safe().
sql/rpl_utility.cc:
  - Fixed valgrind warnings when using c_ptr(). Replaced with 
    c_ptr_safe().

Bug#49836 reports that the geometry type does not work
with WL#5151 applied.

The GEOMETRY type inherits the blob comparison function,
which read the pack length from the metadata. The GEOMETRY
type does not fill in the metadata with anything sensible,
so it is always zero, meaning that the pack length for the
source type is considered zero, rendering it always "smaller"
than the target type which has pack length 4 (without pointer).

This patch fixes the problem by defining
Field_geom::pack_length_from_metadata() to always use the
same as Field_geom::row_pack_length().

Force use of c-register in CAS instruction on x86-32 bit architecture, b-register used for push and pop, so don't want to give compile the chance to choose the wrong register
