Fix last commit re. set-constant scriptlet
Related commit:
- https://github.com/gorhill/uBlock/commit/40ea9d69d5d0

Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/947

Restore intended behavior with original commit:
- https://github.com/gorhill/uBlock/commit/14ebfbea279c

The purpose of the original change was to be able to
trap properties which values were `null`.

Fix regression in set-constant scriptlet
Related issue:
- https://github.com/uBlockOrigin/uBlock-issues/issues/947

`Object.prototype` is not an instance of `Object`, but
yet is still a JS object; thus the solution is to
additionally compare against `typeof`.

Improve set-constant.js scriptlet
The scriptlet will now still try to trap a specific
property if a segment of the chain is not undefined
while yet not an object either.

For example, this now allows to set a value on
`document.body.onselectstart` when `document.body` has
not been instantiated yet by the browser parser,
whereas this would previously fail because
`document.body` would be `null` while the scriptlet
was testing against `undefined`.

Allow re-entrance in abort-current-inline-script
Related feedback:
- https://github.com/DandelionSprout/adfilt/issues/7#issuecomment-590391877

If a property is already trapped with a getter/setter,
propagate to these after validation succeed.

Minor improvement to set-constant scriptlet
Disregard type matching for when the target property
is `null` or is set to `null`.

Convert new setTimeout-if scriptlet to blacklist approach
As per feedback from filter list maintainers, the
whitelist approach has been deemed to confusing.

The scriptlet has been renamed `no-setTimeout-if`
alias `nostif` to reflect the blacklist approach.

`setInterval-if` has been Similarly changed to
`no-setInterval-if` alias `nosiif`.

Add json-prune.js scriptlet
The scriptlet will trap calls to JSON.parse, and
if the result of the parsing is an Object, it
will remove specified properties from the result
before returning to the caller.

Usage:

    ##+js(json-prune, arg1, [arg2])

Where:

- arg1: a list of space-separated properties to remove

- arg2: optional, a list of space-separated properties
        which must be all present for the pruning to
        occur

Example:

    ##+js(json-prune, enabled, adpath config)

A property in a list of properties can be a chain
of properties, example: adpath.url.first

Ability to negate delay in new setTimeout-if scriptlet
This also apply to setInterval-if. Thus to defuse
calls to setTimeout(fn, 1000), the filter could be:

    ##+js(stif, , !1000)

Meaning "allow setTimeout if the delay is not 1000".

Add two scriptlets: setTimeout-if and setInterval-if
Usage is similar to that of raf-if introduced in
commit 6831967f5f.

The two new scriptlets are meant to replace:
- setTimeout-defuser
- setTimeout-logger
- setInterval-defuser
- setInterval-logger

setTimeout-logger and setInterval-logger have been
removed, since they are not to be used in production.

To log setTimeout and setInterval usage, respectively
(using aliases):
- ##+js(stif)
- ##+js(siif)

To defuse setTimeout unconditionally:
- ##+js(stif, !)

Usage of setTimeout-defuser and setInterval-defuser
is deprecated and will be removed in some future when
they are no longer in use.

Keep in mind that the new scriptlets function on a
whitelist basis, whereas the deprecated ones
function on a blacklist basis. Prefixing the needle
with `!` allow to use the new scriptlets on a
blacklist basis.

Add new scriptlet to defuse calls to requestAnimationFrame
Scriptlet name: `raf-if.js`

Usage: `example.com##+js(raf-if, !/(\d+){4}/)`

Argument: one single argument, which is the "needle" to
find in the stringified argument passed to
requestAnimationFrame.

requestAnimationFrame will be defused when:

- The needle is not prefixed with `!` and the needle
  does not match the stringified argument; OR
- The needle is prefixed with `!` and the needle
  matches the stringified argument.

The `raf-if.js` scriptlet will log calls to
requestAnimationFrame to the console when no parameter
is provided, i.e.:

    example.com##+js(raf-if)

Otherwise no logging occurs.

Remove code unused in next release
Since https://github.com/uBlockOrigin/uBlock-issues/issues/156
won't be fixed in next release, no need to ship
with code which will be unused, and anyways only once
the fix is worked on will it be clear exactly what needs
to be used by scriptlets to deal harmoniously with
property listener collisions.

Use `Reflect.construct(t)` rather than `new t()`
Using `new` seemed to work but it's maybe
semantically better to use `Reflect.construct`.

Fine tune new resources-related code
Make sure the parser is safely compatible with old
resources format -- for those users still using
custom resources (via `userResourcesLocation`).

Prepare code for future fix to
<https://github.com/uBlockOrigin/uBlock-issues/issues/156>:

This commit introduces a new private Map() object,
`uBOSafe`, accessible by all injected scriptlets. This
private safe can be used to store data which can be shared
with different scriptlets. The idea is for scriptlets to
use that safe to graciously deal with the need to install
multiple listeners for the same property.

Finalize converting resources.txt into immutable resources
With hindsight, I revised decisions made earlier during
this development cycle:

Un-redirectable scriptlets have been removed from
/web_accessible_resources and instead put in the new
/assets/resources/scriptlets.js, which contains all
scriptlets used for web page injection purpose.

uBO will no longer fetch a remote version of built-in
resources.

Advanced setting `userResourcesLocation` will still be
honoured by uBO, and if set, will be fetched every
time at least one asset is updated.
