  Injector to inject rows into the MySQL server.
  
  The injector class is used to notify the MySQL server of new rows that have
  appeared outside of MySQL control.
 
  The original purpose of this is to allow clusters---which handle replication
  inside the cluster through other means---to insert new rows into binary log.
  Note, however, that the injector should be used whenever rows are altered in
  any manner that is outside of MySQL server visibility and which therefore
  are not seen by the MySQL server.

RESPONSIBILITY

The class contains constructors to handle several forms of
          references to tables.  The constructors can implicitly be used to
          construct references from, e.g., strings containing table names.

EXAMPLE

The class is intended to be used *by value*.  Please, do not try to
          construct objects of this type using 'new'; instead construct an
          object, possibly a temporary object.  For example:

injector::transaction::table tbl(share->table, true);
            MY_BITMAP cols;

PARAMETER(S)

target_state
              The state we are moving to: TABLE_STATE if we are
              writing a table and ROW_STATE if we are writing a row.

DESCRIPTION

The internal state will be updated to the target state if
          and only if it is a legal move.  The only legal moves are:

START_STATE -> START_STATE
              START_STATE -> TABLE_STATE
              TABLE_STATE -> TABLE_STATE
              TABLE_STATE -> ROW_STATE

That is:
          - It is not possible to write any row before having written at
            least one table
          - It is not possible to write a table after at least one row
            has been written
