  This file is the tail end of the sqlite3-api.js constellation,
  intended to be appended after all other sqlite3-api-*.js files so
  that it can finalize any setup and clean up any global symbols
  temporarily used for setting up the API's various subsystems.

  In Emscripten builds it's run in the context of what amounts to a
  Module.postRun handler, though it's no longer actually a postRun
  handler because Emscripten 4.0 changed postRun semantics in an
  incompatible way.

  In terms of amalgamation code placement, this file is appended
  immediately after the final sqlite3-api-*.js piece. Those files
  cooperate to prepare sqlite3ApiBootstrap() and this file calls it.
  It is run within a context which gives it access to Emscripten's
  Module object, after sqlite3.wasm is loaded but before
  sqlite3ApiBootstrap() has been called.
