Ensure scriptlet logging information make it to destination
Avoid race conditions between isolated world-side broadcast channel
and main-side broadcast channel, so as to not lose logging
information if the isolated world-side is not yet ready to
receive through its broadcast channel.

Additionally, added new scriptlet: `trusted-replace-argument`.

[...]##+js(trusted-replace-argument, fn, argpos, argval [,condition, pattern])

Where:

- `fn` is the function we want to proxy through an `apply` handler.
  This can also be a class, in which case the scriptlet will proxy
  through `construct` handler. At the moment, `fn` must exist at the
  time the scriptlet executes.

- `argpos` is the 0-based position of the argument we want to change

- `argval` is the value we want to have for the argument -- the value
  is interpreted the same way the value for `set-constant` is
  interpreted.

- `condition, pattern` is a vararg which tells the scriptlet to act
  only if `pattern` is found in the argument to overwrite.

Example of usage:

uBlock Origin (uBO)

BEWARE! uBO is (and has always been) COMPLETELY UNRELATED to the website ublock.org.

uBlock Origin (uBO) is a CPU and memory-efficient wide-spectrum content blocker for Chromium and Firefox. It blocks ads, trackers, coin miners, popups, annoying anti-blockers, malware sites, etc., by default using EasyList, EasyPrivacy, Peter Lowe's Blocklist, Online Malicious URL Blocklist, and uBO filter lists. There are many other lists available to block even more. Hosts files are also supported. uBO uses the EasyList filter syntax and extends the syntax to work with custom rules and filters.

You may easily unselect any preselected filter lists if you think uBO blocks too much. For reference, Adblock Plus installs with only EasyList, ABP filters, and Acceptable Ads enabled by default.

It is important to note that using a blocker is NOT theft. Do not fall for this creepy idea. The ultimate logical consequence of blocking = theft is the criminalization of the inalienable right to privacy.

Ads, "unintrusive" or not, are just the visible portion of the privacy-invading means entering your browser when you visit most sites. uBO's primary goal is to help users neutralize these privacy-invading methods in a way that welcomes those users who do not wish to use more technical means.
