Change backing store fetch operation to always perform the allocations
...
The fetch API previously allowed for the caller to supply the storage,
this was never used and was preventing the refactoring necessary for
small black storage to be available.

Compute the element index once and use that as a parameter.
...
Change to computing the element index from the flags passed to store
and fetch methods instead of passing the flags around and calculating
everywhere.
Additionally split out writing element of entry to file into distinct
function to make code clearer.

Improve backing store control data serialisation
...
By scheduling the control data to be maintained (entries index written
and headers updated) once activity occurs to update these control
structures rather than a single serialisation at browser exit the data
is more likely to be up to date and not lost on a crash.
