If dom_to_box is still in progress when we destroy an HTML
content, we need to cancel the conversion otherwise we will
end up with a scheduled callback into infinity.

In further preparation for the auth and cert queries being handled
as special contents from `about:` this excises the query pathway
from the llcache pretty much entirely.

removes the CONTENT_MSG_ERRORCODE message kind.

Currently only supporting text input, password input, and hidden
input, along with text areas, this mirrors the text values in
and out of the DOM, allowing JS to adjust the gadget values and
for the gadget values to be interrogated from JS.

In order to cope when an entire document is `visibility: hidden`
we default to the <HTML> node when interacting with the document
to ensure we don't drop off the end of the box model without
identifying at least one node to fire events at.
This resolves#2658

Since executing a script can cause more scripts to be appended
to the script array, and that can cause a reallocation which might
move the script array, reacquire the script pointer after running
the script so that we don't wander off into the reeds.

When appending stylesheets to the selection context, it now
takes the media query string associated with the sheet, rather
than the type bitfield.
TODO:
We need to pass all the sheets in, with their full media
query string, rather than filtering it ourselves and setting
the ones we pass in to "screen".

LibCSS now takes the client media spec, rather than just the
media type we're selecting for.

Previously we correctly used the viewport width, but we were using the
document height instead of viewport height when an HTML child content
triggered a reformat of the parent HTML document.
Trying to reason about error propagation and resource leakage within
the form submission code was impossible because of the
form_successful_controls_dom function.
This function was over six hundred lines long, had twenty six top
level local variables and six levels of indent in places.
This commit splits it out into thirteen shorter and more obvious
functions. The resulting operation is identical except errors are
properly propagated (all failures were reported as out of memory)
and resource management can be reasoned about.
The compiler appears to inline the entirety of the code from
form_submit() down excepting a handful of leaf functions. This
results in similar code output size as previous implementation.
The new implementation has a greater number of variables passed to sub
functions than desirable because multiple character sets are required
to encode names and values in the multipart data list. However as
noted the compiler effectively inlines all these functions so this
does not actually become a major problem.
