This should improve usability of uBO's hard-mode
and "relax blocking mode" operations. This is the
new default behavior.
The previous behavior of forcing a reload of the
page can be re-enabled by simply setting the `3p`
bit of the advanced setting `blockingProfiles`
to 1.

Not much can be done beside reporting to tabless network
requests to all tabs for which the context is a match.
A short term local cache is used to avoid having to iterate
through all existing tabs for each tabless network request
just to find and report to the matching ones -- users
reporting having a lot of opened tabs at once is not so
uncommon.
When no-fetch-if scriptlet is used without argument, the
parameters passed to no-fetch-if will be output to the
console, as `uBO: fetch([...list of arguments...])`.
The new scriptlet allows to defuse calls to fetch() by returning
a promise which always resolve to an empty response.
There is only one argument, which is a space-separated list
of conditions which must be ALL fulfilled in order for the
defusing to take place.
Each condition is a pair of property name and property value
separated by a column. Valid property names are those
documented as valid `init` options:
https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/fetch
The URL of the fetch() is a special case and does not have to
be associated with a property name. Example of usage:
...##+js(no-fetch-if, method:HEAD)
Which means: defuse the call to fetch() if there is an
explicit option which contains `HEAD`. Another example:
...##+js(no-fetch-if, adsbygoogle.js)
Which means: defuse the call to fetch() if the URL contains
`adsbygoogle.js`. Multiple conditions can be provided:
...##+js(no-fetch-if, adsbygoogle.js method:HEAD)
If at least one condition does not match, the defusing will
not take place.
The string against which to match can be a literal regular
expression:
...##+js(no-fetch-if, /adsbygoogle.js$/ method:/HEAD|POST/)
Additonally, the following deprecated scriplets have been
removed:
- requestAnimationFrame-if.js
- setInterval-defuser.js
- setTimeout-logger.js
