ef893b1d66 The base64.wasm=1 flag to ext/wasm/GNUmakefile tells it to embed each resulting WASM file directly in its counterpart JS file base64-encoded. This is roughly 20% larger and saves a network request but is overall less efficient so will not be the new default. It may be interesting for custom builds, in particular for server-side node.js.

1f2bc0ea64 Add support for (make base64.wasm=1), which embeds sqlite3.wasm into its corresponding JS file as base64. A very expensive calculator which was fed the resulting file sizes assures me that the two-file approach is, in the aggregate, more efficient both in terms of overall network bandwidth (+~20% bigger for base64) and client-side memory usage (streaming vs non-streaming wasm compilation), so we'll shelve this as an interesting experiment or maybe for use by custom builds.

379e111bff An initial attempt at embedding sqlite3.wasm into sqlite3.js using base64. This produces a chicken-egg situation in the build because the input file where the blob belongs is injested by emscripten (which generates the wasm file from which that blob is to be generated), so it does not work as-is but is being set aside for later. We'll need to add a second preprocessing step which uses a different #directive delimiter to keep it hidden inside the first pass, then squeeze the wasm file in through there.
