del_table_copy grabs a write lock in a new process in prepare_op/3 to
change 'where_to_read' when a table copy is updated.
When del_table_copy(schema, Node) is called all copies located on Node
are deleted, and thus many locks are taken. Since this was done outside
of the schema-transaction, mnesia's deadlock prevention algorithms
was sidestepped and a deadlock could occur.
Fix by always grabbing write-locks for all changed tabs early and in the same
transaction, this might slow done the operation some but it must be done
and it also cleans up the code.

Introduced a leak of disk_log processes in the rewrite to try-catch.

There is no need to update the index table if a record is updated in non
indexed field. This removes one timing glitch where dirty_index_read would
return an empty list for records that where updated.
There is still an issue with dirty_index_read when updates are made to
the index field, it have been reduced but the real table updates are made
after the index table references have been added.
Originally reported by Nick Marino in erl-questions mailing list, thanks.

The docs express that exit({aborted, Reason}) are called when
an error occur.

match_object returned wrong objects when matching on non key fields
and updates in the same transaction had been performed.

Need to re-raise the match macro if inside transaction

For performance reasons the file data is not synced to disk in mnesia,
data loss can happen between each dump.
mnesia:dump_log() can be used explicitly to ensure data is written to disk.
But that can take a long time, so mnesia:sync_log() which just
sync the log have been added.

dirty_update_counter returned the wrong value when a subscriber existed
and no events was sent. Thanks Anton Ryabkov.

If mnesia:cleartable/1 was called during a table_load an schema event
with delete and write of that table is sent, which caused the table
to contain the schema record instead of clearing the table.

table index
In case of bag tables, trying to delete a non-existing object leads to
the index becoming corrupt. This happens if the non-existing object we
try to delete happens to share its key and index field value with a single
existing object in the table.
Result: The index entry corresponding to the existing object is
removed.
