Non-standard namespaces other than Deno declared in lib.deno_runtime.d.ts

[nayeemrmn]

As you can see, lib.deno_runtime.d.ts publicly declares namespaces domTypes, blob, consoleTypes, event, customEvent, eventTarget, io, fetchTypes, textEncoding, timers, urlSearchParams, url, workers, and performanceUtil which should all be internal.

You can't declare them as variables in typescript - let url; throws during compilation:

error TS2451: Cannot redeclare block-scoped variable 'url'.

► $asset$/lib.deno_runtime.d.ts:2514:19

2514 declare namespace url {
                       ~~~

  'url' was also declared here.
...

Oops! Declaration files are hard.
Fixes to lib.deno_runtime.d.ts with tests are welcome.

Personal opinion, let's address this as part of #2868. Library files work differently, they need to follow the pattern of other lib files. I understand the problem and we should be able to address it as part of #2868. For now, if the collision is a real problem, let's just rename url to something like __url or _deno_url here.

Looks like I broke the curl example because of this:

deno/std/examples/curl.ts

Line 2 in efd7e78

const url = Deno.args[1];

Note: This must mean we're not executing, or even compiling, the examples as part of testing.
