8efeb16b82 Merge 'bindings/wasm: "SELECT 1" benchmark' from Pekka Enberg 
This adds a benchmark for "SELECT 1" that essentially just evaluates the
overhead of calling into the library. Looks like WebAssembly adds 2.5x
overhead compared to native code...

82ec900b07 bindings/wasm: Fix VFS.sync() function signature 
We don't expect any return value from the underlying `fsync()` so fix
the function signature accordingly.

Fixes the following obscure error:

71ac1eacb7 Merge 'btree: cursor with lineal stack structure' from Pere Diaz Bou 
Removed MemPage from the code in favor of an array to encode the stack
of the cursor. This is both simpler and better in terms of memory
access.
O_DIRECT was removed from WAL file as it introduces alignment
constraints that are too hard to follow in regular appends. Maybe in the
future?

Closes #378
