b9f3f6b672 Add the "dbhash.exe" utility program that computes a SHA1 hash over the 
invariant content of an SQLite database file.  Free space in the file, the
page size, auto_vacuum status, text encoding, and so forth do not change the
hash.  Only the content matters.

5cd22006ef Btree interface refactoring: 
(1) The sqlite3BtreeKeySize() interface is renamed to sqlite3BtreeIntegerKey()
and modified to work only for table btrees with a rowid.
(2) The sqlite3BtreeDataSize() interface is renamed to sqlite3BtreePayloadSize()
and modified to work with any btree.
(3) The sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() routines are
combined into a single sqlite3BtreePayloadFetch() routine.
The result of these changes is a smaller binary and fewer CPU cycles needed
to run queries.

a7c90c42ea Change the sqlite3BtreeKeySize() interface into sqlite3BtreeIntegerKey() and 
make it only work for table btrees.  Change sqlite3BtreeDataSize() into
sqlite3BtreePayloadSize() and make it work for all btrees.  Combine
sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() into a single
sqlite3BtreePayloadFetch() routine.  These changes seem to make the
b-tree interface more rational and they reduce both binary size and
CPU usage.

external data sources that do not have a convenient way of computing a unique
