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.
Since resources are now immutable, by default they are
only compiled once each time uBO updates to a new
version. However I need a way to force a re-compiling
of the resource in the dev build. This commit adds code
to invalidate the resources selfie when forcing the
update of any filter list.
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.

The `behnind-the-scene` context was wrongly used to
evaluate the whitelist status of the context of tabless
network requests. The document origin must be used
instead when it's available.
Additionally, much code has been revisited for better
ES6 syntax compliance.
The goal is to be able to specify a scriptlet token
without the `.js` part at the end, because that part
is essentially redundant with the `+js` part of
the syntax.
When the next stable release is in widespread use
(to determine), scriptlet tokens will have to be
specified without the `.js` part, and with this
commit the logger will already report the normalized
version of scriptlets.
Eventually, when the migration to sans-`.js` is
complete (also to determine), the internal
normalization of the token will be removed and this
will become official syntax.
Filter list maintainers will have to mind that
uAssets is becoming in use beyond uBO (i.e. Brave)
when skipping the `.js` part -- hopefully Brave will
go along with the change here, which is to remove a
bit of tediousness for filter list maintainers.
