35db31b24b Add the CSV extension to the test fixture. Fix a memory leak in the CSV 
extension.  Add test cases for the CSV extension, including one that uses
a WITHOUT ROWID virtual table participating in the OR optimization.

62340f8498 An experimental branch with code that allows virtual tables to be declared 
as WITHOUT ROWID tables. This might be useful for virtual tables that model
external data sources that do not have a convenient way of computing a unique
rowid.  The current check-in almost works, but there are still serious issues.

fe912510ea Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary. This means that if a power failure or OS crash occurs very soon after such a transaction is committed, it may be lost following system recovery.
