9885c76c4c Extend wasm build to enable inclusion of client-custom C code, initialized via the SQLITE_EXTRA_INIT mechanism, per discussion in [forum:1e1c04f3ed1bc96b|forum post 1e1c04f3ed1bc96b].

d7ddec765c When a table-valued function appears as the right table of a RIGHT JOIN, 
the argument constraints on the table-valued function should be considered
part of the ON clause of the RIGHT JOIN.  Fix for the problem reported
by [forum:/forumpost/422e635f3beafbf6|forum post 422e635f3beafbf6].  Test
cases in TH3.  Possibly related to the enhancement at [501609eddf2a46d5].
