As was basically decided already a while ago, remove - in the simplest
possible way - the archiving of both qemu-s and mini-os from tarball
generation.
With this the subtree-force-update-all prereq isn't needed anymore in
the top level Makefile. That goal, including the respective ones
underneath tools/, then also are unreferenced and hence are being
dropped, too.

CET Indirect Branch Tracking is a hardware feature designed to provide
forward-edge control flow integrity, protecting against jump/call oriented
programming.
IBT requires the placement of endbr{32,64} instructions at the target of every
indirect call/jmp, and every entrypoint.
However, the default -fcf-protection=branch places an endbr{32,64} on every
function which far more than necessary, and reduces the quantity of protection
afforded. Therefore, we use manual placement using the cf_check attribute.
It is necessary to check for both compiler and assembler support, as the
notrack prefix can be emitted in certain cases.

The build system of seabios always includes the current time and the
hostname into the resulting binary. To avoid that, it is required to
have a file '.version' in the toplevel directory of seabios-dir-remote.
And it is required to pass EXTRAVERSION= to make because its toplevel
Makefile does not take EXTRAVERSION from environment.
Adjust the code to create a '.version' file with fixed content.

SeaBIOS requires gcc and GNU ld in order to build, so allow setting

the path to the compiler and linker that should be used when building
SeaBIOS.

longer needed due to the ability to select the LD to use for SeaBIOS
builds, so remove it.

There's no need to have shim specific targets, so just use the regular
xen makefile targets in order to build the shim binary.
When the shim is build as part of the firmware directory install the
stripped Xen binary to the firmware directory and place a binary with
symbols in the debug directory.
The objcopy step of the shim build is also removed in this patch:
since the shim is booted in PVH mode there's no need for the resulting
binary to be in elf32 format. Xen can load PVH kernels with either a
32 or 64bit elf header.

Running "make uninstall" does not remove all installed files, a
situation which might cause link related issues if xen is re-installed
in a different location.
In order to make uninstall correctly remove the files it is best
the process should be done recursively by mirroring each "install"
target with an "uninstall" who removes the installed files.
An exception to this rule is uninstalling the files produced by
"qemu-xen-dir-remote" and "qemu-xen-traditional-dir", which are external
to the project. These projects do not implement an "uninstall" target so
the files have to be removed manually.

The use of seabios defconfig kills boot performance of Windows guests
because the default is for the int13 handler to use PIO when accessing
the emulated IDE device.
By instead using a canned configuration with the ATA settings overridden
to enable DMA access (and also wider PIO) boot performance is markedly
improved without the need to use a different (and possibly not supported)
device model.
This patch adds the canned configuration into tools/firmware and modifies
the Makefile rule to copy it into place.

We have four different external trees, and four different naming
conventions for specifying the URL, where they live, and what revision
to check out.
Normalize config options on the following bases:
- QEMU_UPSTREAM
- QEMU_TRADITIONAL
- SEABIOS_UPSTREAM
- OVMF_UPSTREAM
The following suffixes for all trees:
- _URL : A remote repository to clone from
- _REVISION : The revision to check out
And the following suffixes for the qemu trees:
- _INTREE : The location of an inlined tree (for tarball releases)
- _LOC : Where to actually look (either a directory or a URL)
The following parameters are still supported for backwards
compatibility:
- CONFIG_QEMU (=> QEMU_TRADITIONAL_LOC)
- QEMU_REMOTE (=> QEMU_TRADITIONAL_URL)
- QEMU_TAG (=> QEMU_TRADITIONAL_REVISION)
- SEABIOS_UPSTREAM_TAG (=> SEABIOS_UPSTREAM_REVISION)

This patch introduces configuration options allowing to built either a
rombios only or a seabios only hvmloader.
Building option ROMs like vgabios or etherboot is only enabled for a
rombios hvmloader, since SeaBIOS takes care or extracting option ROMs
itself from the PCI devices (these option ROMs are provided by the
device model and do not need to be built in hvmloader).
The Makefile in tools/firmware/ now only checks for bcc if rombios is
enabled.
These two configuration options are left on by default to remain
compatible.

This has finally bugged me enough to do something about it:
make prints `***' when it stops due to an error. With make -j, and/or
with automated build systems, this error marker can be in the middle
of a large logfile. It is useful to be able to search for it.
Therefore change occurrences of `*' to `=' for information and warning
messages. `***' is reserved for cases where the build stops.
A corresponding change is being applied to qemu-xen-unstable.
