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.
The generic bitmap handlers provided by each frontend are called back
from the core and therefore should be in an operation table. This was
one of the very few remaining interfaces stopping the core code from
being split into a library.
The content thumbnailers for each frontend were being provided the
contents url. This was only ever used to call the urldb thumbnail
setting API.
This changes it so the single callsite that passed a valid url adds
the bitmap to that url itself in desktop_history.c instead of forcing
every frontend to require the urldb API.
Additionally the old API could pass the url as NULL which was causing
asserts where this was not an expected parameter value. Because of
this this fixes bug #2286 which was also present in the monkey
frontend as both called nsurl_access() on the url without the NULL
check and caused an assertion.
The local history interface now reports errors to its callers isntead
of inconsistantly waning the user occasionally on error.
The documentation comemhts were also updated to match reality
The browser window common initialisation code returns error codes which
were being ignored. The errors were additionally being reported via
warn_user in inappropriate places within browser history construction.
The netsurf core is driven from numerous operation tables most of
which are now set through a common netsurf_register() interface. The
font and plotting interfaces are currently separate and unlike all the
other operation tables are modified for differing contexts.
This change moves the font operations alongside all the other
operations table and remove unnecessary interaction with the renderers
font internals. Further this also removes the need for css internals
to be visible in frontends.
