The ISA parser used to generate different copies of exec functions
for each exec context class a particular CPU wanted to use. That's
since been changed so that those functions take a pointer to the base
ExecContext, so the code which would generate those extra functions
can be removed, and some functions which used to be templated on an
ExecContext subclass can be untemplated, or minimally less templated.
Now that some functions aren't going to be instantiated multiple times
with different signatures, there are also opportunities to collapse
templates and make many instruction definitions simpler within the
parser. Since those changes will be less mechanical, they're left for
later changes and will probably be done in smaller increments.

These functions were already being treated as psuedo objects and had
properties assigned to them setting what their paths were. That's a bit
unusual and made it less obvious what the code was doing, but also
forced the "system" function to know what all the possible path
searching functions were so that they'd have their "path" property
initialized properly in a central location.
This change introduces a PathSearcFunc class which encapsulates the
mechanisms of the old code and makes it implicitly extensible so that
other path searching functions which might look in other directories
can be added in other places.

The fixed image writer (which was dumping .bmp images only) has been
replaced by the configurable one in HDLcd device. Default format is
Auto, which gives gem5 the freedom to choose the format it prefers.

This commit modifies the default behaviour of the vnc frame dumping
process: rather than using 'Bitmap' as a default parameter value, it is
using 'Auto'. Auto parameter is letting gem5 to choose the most
efficient image format among the available ones.

Originally it was possible to use a Bitmap writer class for dumping a
framebuffer snapshot in a .bmp file. This patch enables you to choose
another format. In particular it implements the writing of PNG Images
using libpng library. The latter has to be already installed in your
machine, otherwise gem5 will default to the Bitmap format. This
configurable writer has been introduced in the VNC frame dumping mechanism,
which is storing changed frame buffers from the VNC server

Despite online documentation, the type used for sin_addr.s_addr is not
actually an unsigned long, it is an in_addr_t. When an unsigned long is a 64
bit value, the endian conversion moves the relevant bits of the 32 bit
in_addr_t to positions which are truncated away. This forces the value to 0
which means to bind to any interface, the opposite of the intended effect.

ARM systems require the coordination of the global and local
monitors. When the system is run without caches the global monitor is
implemented in the abstract memory object. This change adds a callback
from the abstract memory that notifies the local monitor when the
global monitor is cleared.
Additionally, for ARM systems the local monitor signals the event
register and wakes the thread context up. Subsequent wait-for-event
(WFE) instructions will be immediately signaled.

The O3CPU allows stores to commit before they are completed and as
soon as they enter the store queue. This is the reason why stores are
verified by the the checker CPU, separately, once they complete
and after they are sent to the memory.
Store conditionals, on the other hand, have an additional writeback
stage in the pipeline as they return their result to a register,
similarly to loads. This is the reason why they do not commit
before they receive a response from the memory. This allows store
conditionals to be verified by the checker CPU as soon as they
commit in the same way as all other non-store insturctions.
At the same time, the presense of a checker CPU should not require
changes to way we handle instructions. This change removes explicit
calls to:
* incorrectly set the extra data of the request to 0 (a subsequent
call to completeAcc already does this without making any ISA
assumptions about the return value of the failed store conditional)
* complete failing store conditionals

NullSimObject doesn't have a has_parent function, and it's not clear what its
return value should be if one were added. The appropriate value seems to
depend on why some other bit of code is checking if there's a parent in the
first place.
In SimObjectVector, the has_parent function is checking whether all of its
elements have a parent. In this particular case, the most reasonable thing
to do seems to be to just skip those elements.

This map is intended to map from request MasterIDs to master names. It could
be used to map to arbitrary strings in other situations, however.
The original idea to store this information was to add a new message type
which would store one ID and the string associated with it. This change stores
the IDs in the header instead so that they'll be easy to find and all
available before the packet data.
One downside of this approach is that it won't be possible to add new master
ID strings as they come up during a trace. If that becomes an issue, the two
approaches could be combined and messages could be added which would augment
the map in the header.
Also worth mentioning is that the proto2 version of the protobuf description
language does not support the "map" field type, and the protoc compiler on my
workstation doesn't support proto3. Because that's such an appropriate
representation for this data, the map is represented in an equivalent format
described in the proto3 documentation.

There's a spot for it in the packet trace protobuf, so we should fill it
with something.

That can be recorded in a packet trace.

* When dispatching multiple gem5 simulations at once, they race
for the socket id, resulting in a panic when calling 'bind'. To
avoid this problem, the socket id is now created before the diod
process is created. In case of a race, a panic is called in the
gem5 process, whereas before the panic was called in the diod
process where it didn't have any effect.
* In some cases killing the diod process in terminateDiod() using
only SIGTERM failed, so a call using SIGKILL is added.

The primary difference between loadState and unserialize, at least when
eventually using the default SimObject implementation of loadState, is that
unserialize is called only if there's a corresponding section in the
checkpoint being restored. In this particular case, the AlphaProcess class
calls the generic Process unserialize function, and that does other critical
initialization like set up the processes page table. If the unserialize
function isn't called, other serious problems would break the simulation
anyway.
This removes the final custom implementation of loadState.

The primary difference between using loadState and letting the default
implementation of loadState call unserialize is that whether or not that code
is called is dependent on that object being associated with a section in the
checkpoint file being unserialized. Since there's always a "root" object,
there should always be a section for it in the checkpoint and those should be
equivalent.
This removes one custom implementation of the loadState function.
