00c3ef2df9 Fix a possible infinite loop in VACUUM that can come up when the schema 
has been carefully corrupted.  Problem discovered by OSSFuzz. Test cases
in TH3.

75ba676790 Fix an issue that was causing the new database image to be assembled entirely 
in heap memory when VACUUMing a database, even if it should use a temp file.
This could cause SQLITE_NOMEM errors when vacuuming very large databases on
32-bit systems.

9ef5e7708a Add the capability to VACUUM an attached database by specifying the schema 
name as an argument to the VACUUM command.  Since version 2.0, VACUUM has
accepted an argument which was silently ignored.  Now it has meaning.

81028a455d The former sqlite3ResetInternalSchema() routine was really two different 
routines, selected by parameter, each with a confused mission.  So split
this routine up into three separate smaller routines, calling each
separately as needed.  Hopefully this will make further refactoring and
schema reset collateral damage containment easier.

c7792fa052 Begin a series of changes designed to reduce the scope and frequency of 
invalidating schemas.  Design goals are that the internal schema should
never be deleted out from under a prepared statement that is running and
that all prepared statements should be expired if the schema is invalidated.
At the same time, minimize the number of schema invalidations.  This change
merely revises the sqlite3ResetInternalSchema() function to use -1 as the
wildcard for "all" rather than 0, so that we can reset the main schema
independently of all the others.
