fa0763eb34 Add extra tests for the error messages generated by sqlite3_declare_vtab() when passed something other than a well-formed CREATE TABLE statement.

c72953a4bc The sqlite3_declare_vtab() interface should return SQLITE_ERROR, not 
SQLITE_MISUSE when a nonsense SQL input is provided, for legacy compatibility.

are both made obsolete by the previous fix on this branch.

5d783d5c84 Fix aggregate function processing to correctly deal with OOMs inside of 
sqlite3ParserAddCleanup(). 
(dbsqlfuzz b2d11ca70e55ee8bde48ae0b53fa3e9355812f95).
Also add improved testing support by causing sqlite3FaultSim(300) to
simulate an OOM inside of sqlite3ParserAddCleanup() and by adding
improved fault-sim support to the CLI.

different ways:  (1) Omit the call to PRAGMA integrity_check('X') that was
being done after CREATE TABLE "X" because the result was being ignored and
the integrity_check was not doing anything other than burning CPU cycles.

is in fact a string that looks like a number.
