If a term of an ORDER BY or GROUP BY contains an aggregate function or column, then it is not an alias that needs to be resolved, so don't try to. This fixes a harmless assertion found by dbsqlfuzz. (check-in: e7ba2af5a1 user: drh tags: branch-3.44)

Fix the SQLITE_ALLOW_ROWID_IN_VIEW bug-compatibility option so that it works again.

Change the SQLITE_CONFIG_NO_ROWID_IN_VIEW configuration option to be just SQLITE_CONFIG_ROWID_IN_VIEW (without the "_NO_" in the middle) and give it the ability to turn the option on and off. Otherwise, it is difficult to test. (check-in: 5d412edc2e user: drh tags: rowid-in-view)

Fix the fuzzinvariants.c test module so that it does not generate invariants that depend on rowid when SQLITE_ALLOW_ROWID_IN_VIEW is used, since rowid values can be unreliable in that context. (check-in: 0d711aaaa1 user: drh tags: rowid-in-view)

First steps toward getting -DSQLITE_ALLOW_ROWID_IN_VIEW to work again. That compile-time option is untested, undocumented, and unsupported.

Add the "VALUES-as-coroutine" optimization. Large VALUES clauses on an INSERT, for example, prepare and run in about half the time and with half the memory. This check-in also includes enhancements to the internal sqlite3ExprIsConstant() routine to recognize pure SQL functions as constant if they have constant arguments.

Attempt to use the Dekker high-precision floating point algorithm in the ext/misc/totype.c extension. This check-in should have been derived from trunk, not the exp-values-clause2 branch. But that's ok, because both trunk and the branch are the same in all aspects that relate to this check-in and this check-in is just parking the proposed enhancement for future consideration - it is not a serious proposal at this point.
