6575856624 os: Split Session_label from Session_policy
By splitting Session_policy into two classes, we make it more flexible.
Originally, the constructor accepted solely an args string, which made it
unusable for situations where we already have extracted the session
label (e.g., stored in the session meta data of a server). Now, the
extraction of the label from the args string is performed by the new
Session_label class instead, which, in turn, can be passed to the
constructor of Session_policy.

This change causes a minor API change. The following code

  Session_policy policy(session_args);

Must be turned into

  Session_label  label(session_args);
  Session_policy policy(label);

8243329ad4 os: Move Genode::Config into 'config' library
Originally, the convenience utility for accessing a process
configuration came in the form of a header file. But this causes
aliasing problems if multiple compilation units access the config while
the configuration gets dynamically updated. Moving the implementation of
the accessor to the singleton object into a library solves those
problems.

21462cdbd2 base: Add const qualifiers to 'util/list.h'
This patch adds support for iterating through a const list. This allows
users of lists to be more rigid with regard to constness. Furthermore,
the patch adds the function 'List::insert_at' for inserting an element
at a specified position. By adding this function, we can remove code
duplication in nitpicker.

6d837c9e26 Attach affinity information to session requests
This patch extends the 'Parent::session()' and 'Root::session()'
functions with an additional 'affinity' parameter, which is inteded to
express the preferred affinity of the new session. For CPU sessions
provided by core, the values will be used to select the set of CPUs
assigned to the CPU session. For other services, the session affinity
information can be utilized to optimize the locality of the server
thread with the client. For example, to enable the IRQ session to route
an IRQ to the CPU core on which the corresponding device driver (the IRQ
client) is running.

5600328d83 terminal_mux: Clear terminal when activating menu
This patch clears the terminal each time the menu appears and thereby
wipes away artifacts that might occur when combining terminal_mux with
kdb_uart_drv and the kernel prints messages directly.

a61bd71a4f Terminal multiplexer
The new terminal_mux server is able to provide multiple terminal
sessions over one terminal-client session. The user can switch
between the different sessions using the keyboard shortcut C-y,
which brings up an ncurses-based menu.

d1c2a7126a terminal: Generalize character-screen code
This patch moves the further reusable parts of the terminal into public
header files. It also slightly tweaks the color table to give all colors
a similar brightness level.

fae63f4fa9 Merge base libraries into a single library
This patch simplifies the way of how Genode's base libraries are
organized. Originally, the base API was implemented in the form of many
small libraries such as 'thread', 'env', 'server', etc. Most of them
used to consist of only a small number of files. Because those libraries
are incorporated in any build, the checking of their inter-dependencies
made the build process more verbose than desired. Also, the number of
libraries and their roles (core only, non-core only, shared by both core
and non-core) were not easy to capture.

Hereby, the base libraries have been reduced to the following few
libraries:

- startup.mk contains the startup code for normal Genode processes.
  On some platform, core is able to use the library as well.
- base-common.mk contains the parts of the base library that are
  identical by core and non-core processes.
- base.mk contains the complete base API implementation for non-core
  processes

Consequently, the 'LIBS' declaration in 'target.mk' files becomes
simpler as well. In the most simple case, only the 'base' library must
be mentioned.

af66043b79 New Input::Event::FOCUS, rename keycode to code
This patch introduces keyboard-focus events to the 'Input::Event' class
and changes the name 'Input::Event::keycode' to 'code'. The 'code'
represents the key code for PRESS/RELEASE events, and the focus state
for FOCUS events (0 - unfocused, 1 - focused).

Furthermore, nitpicker has been adapted to deliver FOCUS events to its
clients.

b7d1c40460 Terminal: add bg color handling + PDBG
Set the right bg color instead of using a dimmed version of the fg
color. The colors are stored in the first 6 bits of the color index.
Thereby the first 3 bits contain the fg and the second 3 bits the
bg color.

The debug message in _handle_esc_seq5() now shows the sequence in
question.

Fixes #495.

838d867680 Terminal: add explicit handling of sgr0 + sgr seq
sgr0 is currently implemented as a wrapper of sgr(0) which
seems to work fine.

For now we accept but ignore certain sgr sequences like for
example [0;10;1m which is generated by lynx even when using
TERM=linux (I am not sure yet if that's actually valid at all).

it is easier to spot wrong colors when using a program that uses

9a00ad7ae3 Support for dynamic ROM sessions, fix #170
This patch introduces support for ROM sessions that update their
provided data during the lifetime of the session. The 'Rom_session'
interface had been extended with the new 'release()' and 'sigh()'
functions, which are needed to support the new protocol. All ROM
services have been updated to the new interface.

Furthermore, the patch changes the child policy of init
with regard to the handling of configuration files. The 'Init::Child'
used to always provide the ROM dataspace with the child's config file
via a locally implemented ROM service. However, for dynamic ROM
sessions, we need to establish a session to the real supplier of the ROM
data. This is achieved by using a new 'Child_policy_redirect_rom_file'
policy to handle the 'configfile' rather than handling the 'configfile'
case entirely within 'Child_config'.

To see the new facility in action, the new 'os/run/dynamic_config.run'
script provides a simple scenario. The config file of the test program
is provided by a service, which generates and updates the config data
at regular intervals.

In addition, new support has been added to let slaves use dynamic
reconfiguration. By using the new 'Child_policy_dynamic_rom_file', the
configuration of a slave can be changed dynamically at runtime via the
new 'configure()' function.

The config is provided as plain null-terminated string (instead of a
dataspace capability) because we need to buffer the config data anyway.
So there is no benefit of using a dataspace. For buffering configuration
data, a 'Ram_session' must be supplied. If no 'Ram_session' is specified
at construction time of a 'Slave_policy', no config is supplied to the
slave (which is still a common case).

An example for dynamically reconfiguring a slave is provided by
'os/run/dynamic_config_slave.run'.

9e3ecade16 Replace Framebuffer::info by Framebuffer::mode
As a preliminary step for working on issue #11, this patch revisits the
'Framebuffer::info' RPC call. Instead of using C-style out paramters,
the new 'mode()' RPC call returns the mode information as an object of
type 'Mode'. Consequently, mode-specific functions such as
'bytes_per_pixel' have been moved to the new 'Framebuffer::Mode' class.

20213e2c76 Frame skipping for terminal
This patch changes decouples the conversion of the terminal state to
pixels from the write RPC function. Intermediate terminal states
produced by sub sequential write operations do not end up on screen one
by one but only the final state becomes visible. This drastically
improves the speed of scrolling through large text output.
