Fixed problems with original gzio() functions not being able to correctly return lengths of long rows.

Disabling debug printouts for valgrind builds that print unallocated memory.

Removing valgrind memory checks from code.

Patch to fix valgrind warning that uninitialized bytes were written. 
The warning was caused by set_default(), which assumes that the field pointer is pointing
into record[0], while all other functions honors the move_field_offset().

Removing DBUG_DUMP printouts for valgrind builds since they trigger warnings.
Removing valgrind memory checks completely.
Removing bzero() of record when opening table that was added earlier.

Fix to correct behaviour of find_and_fetch_row() for tables that have primary keys stored
in storage engines that support the fast method to fetch rows given a primary key. The
method uses position() to retrieve the key for a given record and rnd_pos() to position
the internal "cursor" at the row. Rnd_pos() returns the found record in table->record[0],
so the record has to be moved to table->record[1] for further processing after calling
find_and_fetch_row().

- When a shared library argument is supplied, it's checked for an OS
specific directory separator. The expected error is different
depending on the separator used. Create OS specific versions of these
tests.

  - Disconnect from transporter before starting to delete objects

Refactored a number of engines to have correct init/deinit. Added pass support for "data" from plugin to plugin generic init to use memory location. 

  
  open_table_from_share did not initialize table->record members. that was
  interpreted as the error by valgrind.
  
  Fixed with bzero-ing the members if compilation with -DHAVE_purify.

This finished the bzero() on varchar patch I wrote a few months ago. It also completes the data_length() method I added to Fields to determine the length of data for a particular data type. I have many uses for this :)

Adding class to handle temporary allocate of memory during write of rows.
Eliminating cut'n-paste error between THD::binlog_{write,update,delete}_row().
