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.

Calculate all cache sizes from single memory cache size option and sanity check
have a single global struct to hold all parameters instead of several individual variables

Current periodic cache clean algorithm is poor and requires replacing with something suitable (probably a segregated LRU)
The speculative load algorithm is likewise poor and only uses the image size to make a decision.
