Alexander Boettcher 92db5d2c4e sel4: limit max relocation memory to 256M
relocation is required, to avoid overlapping phdr in the elf binaries, but
sel4 will fail to boot if bender relocates the images at the end of physical
memory. Limit the physical relocation address to a fixed 256M value, so that
sel4 will work.

Norman Feske 015d319fa7 run: link all files in [run_dir]/genode to core
This way, files copied from the depot are incorporated in addition to
the files explicitly specified as boot modules.

The patch also adds an automatic check for the validity of the XML
syntax of boot modules ending with '.config'.

Norman Feske a196fc171a run: support for accessing depot content
Run scripts can use the new 'import_from_depot' function to incorporate
archive content from the depot into a scenario. The function must be
called after the 'create_boot_directory' function and takes any number
of pkg, src, or raw archives as arguments. An archive is specified as
depot-relative path of the form <user>/<type>/name. Run scripts may
call 'import_from_depot' repeatedly.

An argument can refer to a specific version of an archive or just the
version-less archive name. In the latter case, the current version (as
defined by a corresponding archive recipe in the source tree) is used.

If a 'src' archive is specified, the run tool integrates the content of
the corrsponding binary archive into the scenario. The binary archives
are selected according the spec values as defined for the build directory.
As of now, only x86_32 and x86_64 are supported by the 'depot_spec'
function.

Norman Feske 8c4a2a48ca core: install core-<kernel>.o at bin/
By installing the core object to bin/, we follow the same convention as
for regular binaries. This, in turn, enables us to ship core in a
regular binary archive. The patch also adjusts the run tool to pick up
the core object from bin/ for the final linking stage.

Norman Feske c450ddcb3d Disambiguate kernel-specific file names
This patch removes possible ambiguities with respect to the naming of
kernel-dependent binaries and libraries. It also removes the use of
kernel-specific global side effects from the build system. The reach of
kernel-specific peculiarities has thereby become limited to the actual
users of the respective 'syscall-<kernel>' libraries.

Kernel-specific build artifacts are no longer generated at magic places
within the build directory (like okl4's includes, or the L4 build
directories of L4/Fiasco and Fiasco.OC, or the build directories of
various kernels). Instead, such artifacts have been largely moved to the
libcache. E.g., the former '<build-dir>/l4/' build directory for the L4
build system resides at '<build-dir>/var/libcache/syscall-foc/build/'.
This way, the location is unique to the kernel. Note that various tools
are still generated somewhat arbitrarily under '<build-dir>/tool/' as
there is no proper formalism for building host tools yet.

As the result of this work, it has become possible to use a joint Genode
build directory that is usable with all kernels of a given hardware
platform. E.g., on x86_32, one can now seamlessly switch between linux,
nova, sel4, okl4, fiasco, foc, and pistachio without rebuilding any
components except for core, the kernel, the dynamic linker, and the timer
driver. At the current stage, such a build directory must still be
created manually. A change of the 'create_builddir' tool will follow to
make this feature easily available.

This patch also simplifies various 'run/boot_dir' plugins by removing
the option for an externally hosted kernel. This option remained unused
for many years now.

Norman Feske f54c85e045 Genode application binary interface (ABI)
This patch decouples the kernel-specific implementation of the dynamic
linker from its kernel-agnostic binary interface. The name of the
kernel-specific dynamic linker binary now corresponds to the kernel,
e.g., 'ld-linux.lib.so' or 'ld-nova.lib.so'. Applications are no longer
linked directly against a concrete instance of the dynamic linker but
against a shallow stub called 'ld.lib.so'. This stub contains nothing
but the symbols provided by the dynamic linker. It thereby represents
the Genode ABI.

At system-integration time, the kernel-specific run/boot_dir back ends
integrate the matching the kernel-specific variant of the dynamic linker
as 'ld.lib.so' into the boot image.

The ABI symbol file for the dynamic linker is located at
'base/lib/symbols/ld'. It contains the joint ABI of all supported
architectures. The new utility 'tool/abi_symbols' eases the creation of
such an ABI symbol file for a given shared library. Its result should be
manually inspected and edited as needed.

The patch removes the 'syscall' library from 'base_libs.mk' to avoid
polluting the kernel-agnostic ABI with kernel-specific interfaces.

Stefan Kalkowski 7e1692d997 core: unify handling of boot modules
Instead of solving the problem to deliver ROM modules to core while booting
differently for the several kernels (multi-boot, elfweaver, core re-linking),
this commit unifies the approaches. It always builds core as a library, and
after all binaries are built from a run-script, the run-tool will link an
ELF image out of the core-library and all boot modules. Thereby, core can
access its ROM modules directly.

This approach now works for all kernels except Linux.

With this solution, there is no [build_dir]/bin/core binary available anymore.
For debugging purposes you will find a core binary without boot modules, but
with debug symbols under [run_dir].core.

Christian Prochaska 84ee970e9b run: look for platform boot string at beginning of line
When running the same kernel in a VM as on the host system and the
kernel boot message from the VM appears on the log output, the run tool
assumes that the host machine has rebooted unexpectedly. With this
commit, an unexpected reboot is assumed only if the kernel boot message
appears at the beginning of a line. On base-hw, we enforce a line feed
at the beginning of the boot message as the SPIKE emulator log starts
with the first message of the kernel lacking a line feed.
