0efd37f28b Fix lempar.c so that the shift-reduce optimization works for error processing. 
This is a Lemon issue only and has no impact on SQLite.

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.

fe912510ea Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary. This means that if a power failure or OS crash occurs very soon after such a transaction is committed, it may be lost following system recovery.
