remove unecessary inclusion of desktop search header in content
header which has knock on effect of not having ctype or string
system headers dragged in unecessarily.
Futher this highlighted use of ctype API where internal ascii
processing ought to be used.
In preparation for proper splitting of Javascript support into
heaps and threads, this renames the types and corrects the no-js
builds to still work. At this time no substantive change in
semantics exists, and the duktape build won't work.

Instead of extracting information from the X509 certificate chain in
the fetcher the entire chain is propagated in Distinguished Encoding
Rules (DER) format.
This allows all the information contained in a certificate chain to be
retained which can subsequently be presented to the user
HTML contents reference many other objects. The browser window
needs to know if any of them may not be secure, in which case it
needs to report that in its page state. If other content types
might refer to sub-contents, they will need to define the callback
too.

This was archaic support for rendering images as "overlays",
and avoiding a redraw via the browser window redraw and HTML
contents. Basically it was "plot this image here", but it
was too error prone, so it was removed a long time ago.
These are some last vestiges that made the redraw message
look more complex than it is.
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.

* Fetchers now provide the certificates before headers
* This is propagated all the way to the browser window
* When a query occurs, we retrieve it from there and fire
the query with those stored certificates.
* The serial number is a bignum, store it as hex.

This reworks CONTENT_MSG_ERROR to be structured data and
removes the CONTENT_MSG_ERRORCODE message kind.

Migrate the console enums into netsurf/console.h and add
support so that contents can raise a message to log to
the console.

Add a new interface to the content to allow automaticaly scaled
content redraws. This is intended to replace the thumbnail_redraw
interface with something more generic.
Previously content handler debugging features were accessed by global
variables. This allows the setting of debugging parameters via a
content API giving per content control over debugging features.
Currently only used by the html content handler to toggle global
redraw debugging.
The frontends previously had to use an html renderer API to get the
encoding of a content. This also required the explicit checking of the
contents type rather than using the existing content API to abstract
this knowledge.
Update the API which allows frontends to acquire the page features
(images, link urls or form elements) present at the given coordinates
within a browser window.
By making this an explicit browser_window API and using the browser.h
header for the associated data structure with a more appropriate API
naming the usage is much more obvious and contained.
Additionally the link url is now passed around as a nsurl stopping it
being converted from nsurl to text and back again several times.
Added content interface for search.
Removed bw->cur_search search context. Desktop layer now does nothing
except pass search requests from front end onto the bw's current_content
via the content interface.
Search API reduced to a pair of functions at each level:
{desktop|content|html|textplain}_search
and
{desktop|content|html|textplain}_search_clear
Updated front ends to use simplified search API. Only tested GTK and RO builds.
These confine the search stuff to render/. However search still uses struct
selection. The handling for which is still spread over desktop/ and render/.
Also the render/search code itself still fiddles inside html and textplain
privates.
Keypresses now go via content interface.
Contents don't shove the selection object into browser windows any more.
Contents report selection existence by sending message.
HTML content keeps track of where selections in it exist.
Contents report whether they have input focus via caret setting msg.
Caret can be hidden (can still input/paste) or removed.
Consolidate textarea selection handling.
Make textarea report its selection status changes to client.
Various textarea fixes.
Changed how we decide when to clear selections, and give focus.
