5f4a686f8c Simplification and size reduction to the printf logic. Remove the bFlags 
parameter from sqlite3VXPrintf() and sqlite3XPrintf().  Use sqlite3XPrintf()
instead of sqlite3_snprintf() for rendering P4 values in EXPLAIN output.

fa385edff3 A new approach to very large sqlite3_mprintf() strings: Back out the 
[d655a665] check-in and instead make the size fields in StrAccum unsigned.
Strings generated by sqlite3_mprintf() can now be as large as 2^31-1 bytes.

70528d7868 The top of an index equality loop normally starts with OP_SeekGE and OP_IdxGT. 
This check-in adds a flag to OP_SeekGE such that it fails immediately if
the key is not equal, then jumps over the OP_IdxGT, saving a call to the key
comparison functions.  Consider this check-in a proof-of-concept.  It needs 
improvement before going on trunk.  Some tests fail, but only because they
new use fewer key comparisons than expected (which is a good thing!).
