Norman Feske b723b11b30 Modularize Sculpt OS image creation
This patch equips Sculpt with the ability to customize the system image
in very flexible ways.

All customizable aspects of the image have been relocated from the
former sculpt.run script and the accompanied gems/run/sculpt/ directory
to a new location - the sculpt/ directory - which can exist in any
repository. The directory at repos/gems/sculpt/ serves as reference.

The sculpt directory can host any number of <name>-<board>.sculpt files,
each containing a list of ingredients to be incorporated into the
Sculpt system image. The <name> can be specified to the sculpt.run
script. E.g., the following command refers to the 'default-pc.sculpt'
file:

  make run/sculpt KERNEL=nova BOARD=pc SCULPT=default

If no 'SCULPT' argument is supplied, the value 'default' is used.

A .sculpt file refers to a selection of files found at various
subdirectries named after their respective purpose. In particular, There
exists a subdirectory for each file in Sculpt's config fs, like
nitpicker, drivers... The .sculpt file selects the alternative to use
by a simple tag-value notation.

  drivers: pc

The supported tags are as follows.

*Optional* selection of /config files. If not specified, those files are
omitted, which prompts Sculpt to manage those configurations
automatically or via the Leitzentrale GUI:

  fonts
  nic_router
  event_filter
  wifi
  runtime
  gpu_drv

Selection of mandatory /config files. If not specified, the respective
'default' alternative will be used.

  nitpicker
  deploy
  fb_drv
  clipboard
  drivers
  numlock_remap
  leitzentrale
  usb
  system
  ram_fs

Furthermore, the .sculpt file supports the optional selection of
supplemental content such as a set of launchers.

  launches: nano3d system_shell

Another type of content are the set of blessed pubkey/download files
used for installing and verifying software on target.

With the new version, it has become possible to supply a depot with the
the system image. The depot content is assembled according to the 'pkg'
attributes found in launcher files and the selected deploy config.
The resulting depot is incorporated into the system image as 'depot.tar'
archive. It can be supplied to the Sculpt system by mounting it into the
ram fs as done by the 'ram_fs/depot' configuration for the ram fs.

It is possible to add additional boot modules to the system image. There
are two options.

  build: <list of targets>

This tag prompts the sculpt.run script to build the specified targets
directly using the Genode build system and add the created artifacts
into the system image as boot modules.

  import: <list of depot src or pkg archives>

This tag instructs Sculpt to supply the specifid depot-archive content
as boot modules to the system image. This change eliminates the need for
board-specific pkg/sculpt-<board> archives. The board-specific
specializations can now be placed directly into the respective .sculpt
files by using 'import:'.

To make the use of Sculpt as testbed during development more convenient,
the log output of the drivers, leitzentrale, and runtime subsystems
can be redirected to core using the optional 'LOG=core' argument, e.g.,

  make run/sculpt KERNEL=linux BOARD=linux LOG=core

The former pkg/sculpt-installation and pkg/sculpt-installation-pc
archives have been replaced by pkg/sculpt_distribution-pc, which
references the generic pkg/sculpt_distribution archive. Those pkgs are
solely used for publishing / distribution purposes.
