9cb71d0260 run: Move shared procedure to load/pxe.inc
The install_pxe_bootloader_to_run_dir procedure is required by the tftp
as well as the ipxe load script. Move it to a separate file which is
include by both.

79143f6782 tool/boot: add chain_loader 'unzip'
'unzip' can uncompress and load raw multiboot images and ELF files.

Usage together with the PXE bootloader ease life running the muen hypervisor
together with a Genode/x86_64 VM, where the raw boot image is typically quite
large.

8eec092851 Add support for ipxe load (nova, foc, fiasco)
This makes use of the iPXE sanboot command [1] which downloads and
boots an ISO image directly via HTTP. Therefore, your RUN_OPT needs
both

  --include image/iso   and
  --include load/ipxe

NOTE: The webserver serving the ISO image must support ranged requests,
      see [2].

94afc1a340 run: support loading images via iPXE/HTTP
iPXE is an open source network boot firmware which supports booting from
a web server via HTTP [1].

The following two parameters can be used to specify the iPXE/HTTP setup:

--load-ipxe-base-dir
  This parameter specifies the base directory of the HTTP server from
  which the target machine downloads the files.

--load-ipxe-boot-dir
  The directory relative to iPXE base dir which contains the iPXE
  chainload configuration and all necessary files.

The target machine is expected to request the following iPXE
configuration via HTTP:

http://${HOST_URL}/${ipxe-boot-dir}/boot.cfg

This can be achieved by building iPXE with the following embedded
script:

  #!ipxe
  dhcp
  chain http://${HOST_URL}/${ipxe-boot-dir}/boot.cfg

See also [2] for additional information.

b60f28bee9 run/load/tftp: detect bad directory
If a user has e.g. /tftpboot/x86 as directory and configures
base_dir=/tftboot and offset_dir=/x86, this leads to bad behavior
as the load module creates a symlink

/tftpboot/x86/<builddir> -> <absolut_builddir>

in this case instead of the desired

/tftpboot/x86 -> <absolut_builddir>

Furthermore, the module works on

/tftpboot/x86/config-00-00-00-00-00-00

and

/tftpboot/x86/<builddir>/config-00-00-00-00-00-00

afterwards, which looks bad too. As there is no warning at all, this can
be hard to debug. The commit adds an appropriate check with error message and
exit -1 on an existing directory.
