This new scriplet has become necessary as a
countermeasure to new bypass mechanisms by
some websites, as discussed with filter list
maintainers.

Scriptlet: abort-on-stack-trace
Alias: aost
Argument 1:
The property to trap in order to launch the
stack trace matching code, ex. Math.random
Argument 2:
The string (needle) to match against the stack
trace. If the empty string, always match. There
is a special string which can be used to match
inline script context, <inline-script>.
Argument 3:
Whether to log, and if so how:
Empty string: do not log
1: log stack trace for all access to trapped
property
2: log stack trace for defused access to trapped
property
3: log stack trace for non-defused access to
trapped property
Many filter lists are known to cause serious filtering
issues in uBO and are not meant to be used in uBO.
Unfortunately, unwitting users keep importing these
filter lists and as a result this ends up causing
filtering issues for which the resolution is always
to remove the incompatible filter list.
Example of inconpatible filter lists:
- Reek's Anti-Adblock Killer
- AdBlock Warning Removal List
- ABP anti-circumvention filter list
uBO will use the following resource to know
which filter lists are incompatible:
- https://github.com/uBlockOrigin/uAssets/blob/master/filters/badlists.txt
Incompatible filter lists can still be imported into
uBO, useful for asset-viewing purpose, but their content
will be discarded at compile time.
Reported internally by team.
Explicit conversion was causing an exception to be
thrown when the type argument was not supporting
`toString()`, for example when `type` argument was
literal `null`.

It has been found that the two malware lists uBO uses by
default appear to be essentially no longer maintained.
urlhaus list[1] has been identified by the community as
being well maintained and as being actually useful as a
default malware-related list in uBO, since it's being updated
every day from a database of top domains and specific URLs
identified as serving malicious content. Additionally, the
maintainer of urlhaus list has taken steps to increase
compatibility with uBO[2].
The decision has been to replace the current two malware-
related lists with urlhaus list, which will be enabled by
default in uBO -- and this means that list will be part of
uBO's package from now on.
For those who have the two removed malware lists enabled,
these will be moved to the custom lists section -- they
will still be enabled. It is suggested users remove them from
their selection of lists as their usefulness at this point
is questionable.

Add support for specially-named properties:
`[]`, to iterate through all elements in an array, in
order to deal more graciously with cases where the
property to remove is an element in an array. An
actual case:
+js(json-prune, playlist.movies.0.adserver playlist.movies.1.adserver ...)
Can be now converted to:
+js(json-prune, playlist.movies.[].adserver)
`*`, to iterate through all own properties of an object,
in order to deal with random-named properties. For
example (not an actual case):
+js(json-prune, playlist.*.adserver)
Where `adserver` would be a property member of an
object which is itself a property of `playlist`, but
which name is unknown or is variable.
Specifically:
- Log entries as received by client code
- Prettier and more readable console output
- Ability to only log entries matching a
specific needle
As per internal discussion at
<https://github.com/uBlockOrigin/uAssets>; limited
logging capabilities of json-prune originally raised
by <https://github.com/gwarser>.

To be consistent with no-setTimeout-if.js.
requestAnimationFrame-if.js is deprecated and must no longer be
used, it will be removed in the near future when it's no longer
in use in default filter lists.
no-requestAnimationFrame-if.js is aliased to norafif.js.
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`.
There is no point for such list since it's not possible
to get breakage measurements from using such list and
thus impossible to evaluate.
At the same time, "uBlock filters --- Annoyances" has
been moved to the "Annoyances" section.
