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.
The die() API for abnormal termination does not belong within the core
of netsurf and instead errors are propogated back to the callers.
This is the final part of this change and the API is now only used within
some parts of the frontends
By using an error code return we can gracefully handle fetcher
registration faliures instead of just immediately aborting.
The curl handler was also cleaned up and documentation improved
as a side effect.
The netsurf.h header should *only* contain the registration, core
initialisation and finalisation methods. Version information is best
placed in its own header.
Also remove any unneeded inclusion of this header limiting it to
solely the places the relevant API is required.
This change updates the llcache to use the scheduler to notify users of the
llcache of events. This should be just as safe as before and is part of an
effort to remove hlcache_poll and llcache_poll eventually because fetchers
should schedule themselves if need-be.
This is a big change despite the diminutive nature of the patch. Please report
issues promptly if they turn up after this and are not visible before it.
