descriptive names

Most of the code for handling the table log is in place now, except
the action part at recovery and proper error handling in some places.

Fix a few bugs
sql/table.cc:
fix
There are (at least) two implementations of the checksum
computation. One is in MyISAM for the quick checksum. It
is executed on every row change. The other is in the
SQL layer for the extended checksum. It retrieves all rows
of a table via the respective storage engine.
In former MySQL versions varchars were stored with their
maximum length, but now with their real length similar to
blobs.
This change had been forgotten to take care of in the
extended checksum calculation. Hence too much data was
checksumed. In MyISAM this change had been taken care of
already. Only the real data is included in the checksum.
I changed mysql_checksum_table() so that it uses the
length information of true varchar fields instead
of the field length like in former varchar
implementations.
mysql-test/r/innodb.result:
Bug#8841 - CHECKSUM TABLE is broken in MyISAM
Fixed test results.

Interface changes pushed early.
Separation of public and implementation interface for external_lock()
in preparation for implementation.
sql/handler.cc:
Separating public virtual external_lock() into public non-virtual
ha_external_lock() and private virtual external_lock(). Some minor
changes to ha_*_row() function.
sql/handler.h:
Separating public virtual external_lock() into public non-virtual
ha_external_lock() and private virtual external_lock().
sql/lock.cc:
Using new public ha_external_lock instead of internal external_lock.
sql/opt_range.cc:
Using new public ha_external_lock instead of internal external_lock.
sql/sql_table.cc:
Using new public ha_external_lock instead of internal external_lock.
