fe48599294 Minor simplifications to the "zeroPage()" routine in btree.c.

e0670b6220 Remove the "rowid cache" that sought to remember the largest rowid for a 
table and thereby speed up OP_NewRowid.  That cache was ineffective.
Removing it results in a performance increase of 0.4%, less memory usage,
and a slightly smaller library size.

39a3088dc4 Updates to the command-line shell. Simplify the banner message. Add the

include a banner message warning that the database is transient and in-memory
and mention the ".open" command.

e08ecad58a Do not mark the ephemeral tables used to hold the RHS of IN clauses as 
unordered because the NGQP will use those ephemeral tables to help order the
output.  This is not an issue for standard SQLite since ephemeral tables
there are always ordered, regardless of the hint.  It only affects systems
that substitute an alternative storage engine.
