Generalizd architecture for GEDF-style scheduelrs to reduce code redundancy.wip-refactored-gedf
This patch hoists nearly all of the non-GEDF specific code (decision making (GEDF) vs. carrying out decisions (non-specific)) out of sched_gsn_edf.c and into a new generic sched_global_plugin architecture. A new struct, sched_global_plugin, provides the needed hooks for other GEDF-style schedulers to reuse the non-scheduler-specific code. You may conceptualize this new architecture (in OO-terms) as: * sched_plugin is the parent of sched_global_plugin. * sched_global_plugin is the parent of gsn_edf_plugin. * Both sched_plugin and sched_global_plugin are "pure virtual" This patch drastically reduces the amount of code needed to support G-EDF, EDZL, (Adaptive) EDZL, etc.
