On Nate's advice, overload 'char' as well as 'signed char'
and 'unsigned char'.

30ce620d1d sim: fold StartupCallback into SimObject 
There used to be a reason to have StartupCallback
be a separate object, but not any more.  Now
it's just confusing.

replace priority queue with vector of lists(1 list per stage) and place inside a class
so that we have more control of when an instruction uses a particular schedule entry

also, this is the 1st step toward making the InOrderCPU fully parameterizable. See the
wiki for details on this process

f24ae2ec2a cache: fail store conditionals when upgrade loses race

for store conditionals, so downstream caches can fail
these when they run into invalidations.

57f2b7db11 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.

dd133c7b24 ruby: get rid of PrioHeap and use STL 
One big difference is that PrioHeap puts the smallest element at the
top of the heap, whereas stl puts the largest element on top, so I
changed all comparisons so they did the right thing.

Some usage of PrioHeap was simply changed to a std::vector, using sort
at the right time, other usage had me just use the various heap functions
in the stl.

bc87fa30d7 ruby: get rid of RefCnt and Allocator stuff use base/refcnt.hh 
This was somewhat tricky because the RefCnt API was somewhat odd.  The
biggest confusion was that the the RefCnt object's constructor that
took a TYPE& cloned the object.  I created an explicit virtual clone()
function for things that took advantage of this version of the
constructor.  I was conservative and used clone() when I was in doubt
of whether or not it was necessary.  I still think that there are
probably too many instances of clone(), but hopefully not too many.

I converted several instances of const MsgPtr & to a simple MsgPtr.
If the function wants to avoid the overhead of creating another
reference, then it should just use a regular pointer instead of a ref
counting ptr.

There were a couple of instances where refcounted objects were created
on the stack.  This seems pretty dangerous since if you ever
accidentally make a reference to that object with a ref counting
pointer, bad things are bound to happen.

f92e91e853 Minor remote GDB cleanup. 
Expand the help text on the --remote-gdb-port option so
people know you can use it to disable remote gdb without
reading the source code, and thus don't waste any time
trying to add a separate option to do that.
Clean up some gdb-related cruft I found while looking
for where one would add a gdb disable option, before
I found the comment that told me that I didn't need
to do that.

67766cbf17 ARM: Fix the implementation of the VFP ldm and stm macroops. 
There were four bugs in these instructions. First, the loaded value was being
stored into a floating point register as floating point, changing the value as
it was transfered. Second, the meaning of the "up" bit had been reversed.
Third, the statically sized microop array wasn't bit enough for all possible
inputs. It's now dynamically sized and should always be big enough. Fourth,
the offset was stored as an unsigned 8 bit value. Negative offsets would look
like moderately large positive offsets.
