c0fa4c5f32 Remove internal function sqlite3OsDefaultVfs(). The built-in VFS layers now register their VFS implementations by calling sqlite3_vfs_register() from within sqlite3_os_init(). (CVS 5307)

f6e369a119 Fix a problem in sqlite3ExprIsInteger() causing failures on select1-4.9.2. 
Other bug fixes in compound-merge.  The compound-merge is still disabled
in this check-in using "#if 0" due to additional bugs. (CVS 5295)

92b01d53c2 The compound-select merge optimization is mostly working with this check-in. 
But there are still a few problems and so the optimization is disabled by
and "#if 0".  This check-in is to synchronize with the other changes happening
in parallel. (CVS 5291)
