PeerGroup: add a removePeerFilterProvider to complement add.
1) Re-factored PostgresFullPrunedBlockStore and H2FullPrunedBlockStore into a generic DatabaseFullPrunedBlockStore class.
2) H2FullPrunedBlockStore now supports calculateBalanceForAddress() method.
3) Created an additional store for MySQL (MySQLFullPrunedBlockStore) and unit test.
4) Fixed unit test PostgresFullPrunedBlockStoreTest, second time execution was failing due to not clearing down the tables correctly.
5) Added methods getOpenTransactionOutputs() & deleteStore() to base class DatabaseFullPrunedBlockStore.
1) Fixed the height field to store the height for both coinbase/non coinbase open outputs.
2) Thanks to Ed Lee - Fixed Issue 447 : H2 store: block header hash code is off by 4 bytes. This fix also applies to Postgres and MySQL stores.
3) Added a coinbase field to the openoutputs table and updated code to use this value.
4) Updated field type of ‘value’ in the openoutputs table from bytes to long.
5) Updated the stores (DatabaseFullPrunedBlockStore) with a compatibility check.
6) Updated field type of ‘addresstargetable’ in the openoutputs table from int to tinyint/smallint.
Bug fix: The database access code was not updated on field value type change.
