stacktrace: Provide common infrastructure
All architectures which support stacktrace carry duplicated code and
do the stack storage and filtering at the architecture side.
Provide a consolidated interface with a callback function for consuming the
stack entries provided by the architecture specific stack walker. This
removes lots of duplicated code and allows to implement better filtering
than 'skip number of entries' in the future without touching any
architecture specific code.
