sim: fold checkpoint restore code into instantiate() The separate restoreCheckpoint() call is gone; just pass the checkpoint dir as an optional arg to instantiate(). This change is a precursor to some more extensive reworking of the startup code.

sim: clean up child handling The old code for handling SimObject children was kind of messy, with children stored both in _values and _children, and inconsistent and potentially buggy handling of SimObject vectors. Now children are always stored in _children, and SimObject vectors are consistently handled using the SimObjectVector class.

sim: fail on implicit creation of orphans via ports Orphan SimObjects (not in the config hierarchy) could get created implicitly if they have a port connection to a SimObject that is in the hierarchy. This means that there are objects on the C++ SimObject list (created via the C++ SimObject constructor call) that are unknown to Python and will get skipped if we walk the hierarchy from the Python side (as we are about to do). This patch detects this situation and prints an error message.

sim: make Python Root object a singleton Enforce that the Python Root SimObject is instantiated only once. The C++ Root object already panics if more than one is created. This change avoids the need to track what the root object is, since it's available from Root.getInstance() (if it exists). It's now redundant to have the user pass the root object to functions like instantiate(), checkpoint(), and restoreCheckpoint(), so that arg is gone. Users who use configs/common/Simulate.py should not notice.

bus: clean up default responder code. Clean up some minor things left over from the default responder change in rev 9af6fb59752f. Mostly renaming the 'responder_set' param to 'use_default_range' to actually reflect what it does... old name wasn't that descriptive in the first place, but now it really doesn't make sense at all.

O3CPU: O3's tick event gets squashed when it is switched out. When repeatedly switching between O3 and another CPU, O3's tick event might still be scheduled in the event queue (as squashed). Therefore, check for a squashed tick event as well as a non-scheduled event when taking over from another CPU and deal with it accordingly.

python: Add mechanism to override code compiled into the exectuable If the user sets the environment variable M5_OVERRIDE_PY_SOURCE to True, then imports that would normally find python code compiled into the executable will instead first check in the absolute location where the code was found during the build of the executable. This only works for files in the src (or extras) directories, not automatically generated files.

cache: fix dirty bit setting Only set the dirty bit when we actually write to a block (not if we thought we might but didn't, as in a failed SC or CAS). This requires makeing sure the dirty bit stays set when we get an exclusive (writable) copy in a cache-to-cache transfer from another owner, which n turn requires copying the mem-inhibit flag from timing-mode requests to their associated responses.
