Fixes to the version of "varsep" group_concat so that (1) it builds under separate compilation and (2) omits tabs in source code and (3) runs faster than trunk. This variant of the group_concat_varsep branch might be preferred over the tip because it preserves (undocumented) legacy behavior about the position of separators relative to terms. (check-in: 04399cf9 user: drh tags: group_concat-fix-legacy)

Have the dbstat virtual table take a copy of each page buffer that it traverses instead of just a reference to the page-cache object. This avoids problems if an error causes transaction rollback while a dbstat cursor is open. dbsqlfuzz crash-417224040fee04f0f0e62b70265c518893b08769. (check-in: 6ab25f8b user: dan tags: trunk)

Dbsqlfuzz (a097eaad43c3c845b236126df92fb49b25449b0c) found a way to reach the assert() that was added to sqlite3_declare_vtab() by [eb94f4a8174436b1]. This check-in fixes the problem. (check-in: 857d26a6 user: drh tags: trunk)

Ensure that sqlite_stat1 and sqlite_stat4 are ordinary tables (not views or virtual tables) before trying to load them (dbsqlfuzz bc02a0cde82dee801a8d6f653d2831680f87dca1). This prevents sqlite3_declare_vtab() from running with db->init.busy turned on. Even so, enhance sqlite3_declare_vtab() to be able to deal with db->init.busy being on, in case there are undiscovered paths to that state. Each of these two changes are independently sufficient to prevent the problem fixed by the previous check-in [c7560c1329965ab5] but there is no harm in keeping that third layer of protection in place.
