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.

191dd06195 Revert sqlite3_enable_load_extension() to its original long-standing behavior. 
Add SQLITE_DBCONFIG_ENABLE_LOAD_EXTENSION which will enable only the C-API and
leave the SQL function disabled.

1a55dedf7b <b>API Change:</b> Modify sqlite3_enable_load_extension() so that it only 
enables/disables the load_extension() SQL function, and leaves the C-APIs
enabled at all times.  In this way, applications can enable extension loading
for the C interface without having to expose that capability to the SQL.
