When naively computing the relative path between the git hooks directory and a
hook we want to install, that will generally start with a few ".." path
components to work back out of the .git directory into the working directory.'
If the hooks directory is actually a symlink, then following ".." directory
entries won't get us back to where we came from, they'll take us to the actual
parent directory of hooks. The relative path we computed would then try to go
forward from this other directory using a path that would have worked in the
working directory, hopefully going somewhere that doesn't exist, but
potentially going to a totally unrelated file with the same relative path.
To avoid this problem, we should expand any symlinks in both the hooks
directory path, and the path to the hook script. That way, any ".." components
will go where we'd expect them to, and the relative path will actually go from
hooks to the script we expect.

If the hooks directory is a symlink, then there are at least two possible
scenarios to consider when installing a hook which is itself a symlink. The
first is that hooks is a relative symlink, and so is likely intended to stay
in place relative to .git and the git working directory. In that case, it's ok
for the symlinks inside of hooks to be relative to the working directory too,
since they should also stay in place relatively speaking.
The second situation is that the symlink is absolute. In that case, moving the
git working directory will move the hook relative to the hook directory, and
any relative symlink will become broken. In that case, the hook symlink needs
to be absolute.
The same logic likely applies to the .git directory itself, although I haven't
run into a situation in practice where the .git directory is actually a
symlink.

When installing a git hook, it's possible for the hook to not "exist" if it's
actually a symlink which points to a file that doesn't exist. Trying to create
a new symlink in its place without first removing the old one causes a build
failure in these cases.
If the hook doesn't "exist" but is still a link, that means it's actually a
broken link and should be deleted by the hook installation function before any
new symlink is created.

The GIC model currently adds a delay to interrupts when posting them
to a target CPU. This means that an interrupt signal will be
represented by an event for a short period of time. We currently
ignore this when draining and serialize the tick when the interrupt
will fire. Upon loading the checkpoint, the simulated GIC reschedules
the pending events. This behaviour is undesirable when we implement
support for switching between in-kernel GIC emulation and gem5 GIC
emulation. In that case, the (kernel) GIC model gets a lot simpler if
we don't need to worry about in-flight interrupts from the gem5 GIC.
This changeset adds a draining check to force the GIC into a state
where all interrupts have been delivered prior to checkpointing/CPU
switching. It also removes the now redundant serialization of
interrupt events.

Add a helper function to scan out an entire frame in one time
step. This requires the public PixelPump to be changed somewhat to
separate timing updates from general PixelPump control. Instead of
calling PixelPump::start(timings), timings now need to be updated
using a separate call to PixelPump::updateTimings(timings) before
calling PixelPump::start().
Display controllers that don't need accurate timing (e.g., in KVM
mode), can use the new PixelPump::renderFrame() API to render an
entire frame in one step. This call results in the same callbacks
(e.g., calls to nextPixel()) as the timing calls, but they all happen
in immediately. Unlike the timing counterpart, renderFrame() doesn't
support buffer underruns and will panic if nextPixle() indicates an
underrun.

Gerrit requires that all commit messages have a Change-Id tag. This
tag is added automatically by a commit message hook in Git. Include
the default Gerrit commit message hook and add it automatically using
scons to make life easier for everyone.

the GpuISA class is unused. This changeset removes the member,

GCC when dealing with overrides. This changeset adds the specifier
to the methods which need it to silence the compiler.

The generated decoder header defines macros that represent bit fields
within instructions. These fields typically have short names that
conflict with names in other header files. Include the generated
header after all normal header to avoid this issue.
