We were handling the STYLE tag getting added in the
dom_default_action_DOMSubtreeModified_cb callback, however,
the media attribute dadn't been added by that point.
We now check it in the dom_default_action_DOMNodeInserted_cb
callback, at which time the media attribute is available for
checking.
Note, we should probably store the media type in the
html_stylesheet structure, but for now we just have an
`unused` boolean.
Also, it may be possible to optimise to avoid parsing non-
screen media STYLE element data if we could detect the media
earlier.
When the operations tables were created the browser table was renamed
to miscellaneous except the actual rename patch was never applied,
this fixes that situation.
This changes the LOG macro to be varadic removing the need for all
callsites to have double bracketing and allows for future improvement
on how we use the logging macros.
The callsites were changed with coccinelle and the changes checked by
hand. Compile tested for several frontends but not all.
A formatting annotation has also been added which allows the compiler
to check the parameters and types passed to the logging.
