46de072880 Add the sqlite3changeset_start_v2() - a new version of _start() that accepts a flags parameter - and a streaming equivalent to the sessions module. Also add the SQLITE_CHANGESETSTART_INVERT flag, used with start_v2() to invert a changeset while iterating through it.

f7f2a82aa0 On the first connection to a WAL-mode database that was not cleanly shut down 
and contains a left-over -shm file, truncate the -shm file to 3 bytes instead
of to 0 bytes. Avoiding a truncation to 0 means that system monitoring tools
can better detect if a process illegitimately tries to truncate a -shm file.
Such a rogue process might think it is being helpful by cleaning up old files,
but there is a race condition that can cause damage to the database.
