The GTK resource handling can now provide the path to resources rather
than having to compute them separately. This reduces run time
allocation and allows for the resources to be built in if required.
Additionally this tweaks the resource scheme handling to redirect
favicon.ico to resource:favicon.png instead of rewriting directly to
file scheme path allowing the favicon to be a compiled in resource.
This adds API to obtain direct pointers to arrays of data from
compiled in resources. Additionally it hooks this up to provide data
for the resourece scheme handler.
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.
This rationalises the path construction and basename file
operations. The default implementation is POSIX which works for all
frontends except windows, riscos and amiga which have differeing path
separators and rules.
These implementations are significantly more robust than the previous
nine implementations and also do not use unsafe strncpy or buffers
with arbitrary length limits.
These implementations also carry full documentation comments.
