daa46142ec Rework the code that computes the datatypes and affinities for subqueries 
and views.  If the subquery/view is constructed from a compound SELECT where
the affinity varies across arms of the compound, set the affinity for the
corresponding column in the constructed view to be BLOB so that it is allowed
to take on any data type.

ed07d0ea76 If the SELECT that implements a subquery or a VIEW or a CREATE TABLE AS is

then the overall column type becomes BLOB (ANY).

feb9123a8c Add convenience variants of sqlite3.wasm.peek/poke() for each numeric type to help reduce errors related to typos in the final argument (type-name strings). If wasm.xWrap.FuncPtrAdapter is called as a function, instead of a constructor, it now behaves as if it were called as a constructor (previously it threw an exception).

a8b5c8739c Back out the part of the change in [88a05141c28e5ff1] that adds affinity to 
the materialization of a view, as the affinity can be undefined for a compound
query.  This passes all TCL tests, but shows failures in the TH3 tests derived
from [forum:/forumpost/6f842bc5b2dadcb2|forum post 6f842bc5b2dadcb2], presumably
because the WHERE clause of the query uses constraints of the form
"source_crs_code='8675'" instead of "source_crs_code=8675".  Perhaps further
changes on this branch should reimplement affinity on joins in cases where
the affinity is unambiguous.

7ca4312ff2 Further fix for ticket [57c47526c34f01e8]. If a subquery has a result set 
column of the form "CAST(expr AS NUMERIC)" do not give that column NUMERIC
affinity.  NUMERIC affinity always goes to an integer if able, but a CAST
to numeric is a no-op if the input is a number.  So the two are not equivalent.

89e160a96a If a subquery has a result column of the form "CAST(... AS NUMERIC)" then 
give that column no affinity rather than NUMERIC affinity.  This is because
casting to numeric preserves real values that could be integers but numeric
affinity does not.  By using no affinity on the column, we make the behavior
consistent if the subquery is implemented as a co-routine or is materialized.

33ce0b3ff3 Revert part of [9386d6f63468] because the new automatic function pointer binding cannot properly track per-context function mappings when the context is more complex than a single context-type pointer. e.g. it is fine for sqlite3_trace_v2() but it breaks down with sqlite3_create_collation() because that one needs to use the collation name as part of the context key and we cannot sensibly do so with the current code.

124fc52d96 Move JS-to-C binding signatures from sqlite3-api-prologue.js to sqlite3-api-glue.js to allow for use of the new/experimental sqlite3.wasm.xWrap() feature which automatically binds JS functions to WASM/C as needed, which simplifies creation of bindings which take C function pointers. Reimplement sqlite3_exec(), sqlite3_create_collation(), sqlite3_progress_handler() to use this new feature.

4245667e35 OPFS VFS: add the opfs-unlock-asap=1 URI flag which tells the VFS to release implicit locks ASAP instead of during VFS idle time. This improves concurrency notably in the test app but brings a significant performance penalty in speedtest1 (roughly 4x slowdown). This is not the final word in OPFS concurrency, but gets us a step further.
