Drop support for Edge Legacy: the non-Chromium, EdgeHTML-based Microsoft
Edge version. Also, restrict some workarounds that were applied
unconditionally in all browsers to run only in IE now. This slightly
increases the size but reduces the performance burden on modern browsers
that don't need the workarounds.
Also, clean up some comments & remove some obsolete workarounds.

The `:scope` pseudo-class[1] has surprisingly good browser support: Chrome,
Firefox & Safari have supported if for a long time; only IE & Edge lack support.
This commit leverages this pseudo-class to get rid of the ID hack in most cases.
Adding a temporary ID may cause layout thrashing which was reported a few times
in [the past.
We can't completely eliminate the ID hack in modern browses as sibling selectors
require us to change context to the parent and then `:scope` stops applying to
what we'd like. But it'd still improve performance in the vast majority of
cases.

Latest versions of all browsers now implement focusin & focusout natively
and they all converged on a common event order so it doesn't make much sense
for us to normalize it to a different order anymore.
Note that it means we no longer guarantee that focusin fires before focus
and focusout before blur.

Also, run `grunt npmcopy` to sync the "external" directory with dependencies
from package.json. For example, the Sinon library version didn't match.

Current width/height cssHook reads the computed position style even if not
necessary as the browser passes the scrollboxSize support test. That has been
changed.
This commit also makes the scrollboxSize support test in line with all others
(i.e. only return true or false) and changes the variable name in the hook
to make the code clearer.

The user agent of the iPad with iOS 11.3 on BrowserStack is missing the "iPhone"
part in the "iPhone OS 11_3" part. This commit makes the iOS regex accept such
(probably?) malformed UAs.
A whitelist is available so that some tests can be allowed to always succeed.
This is used only for ajax for now as it can be manually disabled in IE but
is enabled by default.

Support comments that mentioned only Safari < 7 were checked & updated
to account for bugs existing in newer versions as well; Safari 6 support
test results were removed.

This hack turns out to be needed by Android 4.0-4.3.
Add a support test so that the hack is invoked only where needed.

Most browsers were put in order newest to oldest, Android was
treated differently; this has been fixed.
Also, browsers that share test results between different versions were
grouped together.
