Norman Feske 17c79a9e23 base: avoid use of deprecated base/printf.h
Besides adapting the components to the use of base/log.h, the patch
cleans up a few base headers, i.e., it removes unused includes from
root/component.h, specifically base/heap.h and
ram_session/ram_session.h. Hence, components that relied on the implicit
inclusion of those headers have to manually include those headers now.

While adjusting the log messages, I repeatedly stumbled over the problem
that printing char * arguments is ambiguous. It is unclear whether to
print the argument as pointer or null-terminated string. To overcome
this problem, the patch introduces a new type 'Cstring' that allows the
caller to express that the argument should be handled as null-terminated
string. As a nice side effect, with this type in place, the optional len
argument of the 'String' class could be removed. Instead of supplying a
pair of (char const *, size_t), the constructor accepts a 'Cstring'.
This, in turn, clears the way let the 'String' constructor use the new
output mechanism to assemble a string from multiple arguments (and
thereby getting rid of snprintf within Genode in the near future).

To enforce the explicit resolution of the char * ambiguity, the 'char *'
overload of the 'print' function is marked as deleted.

This is the example operating system based on the Genode OS framework:

:_Init_: is the first real process in the system. The provided implementation
  uses a very simple XML parser to read its configuration files.

:_Drivers_: The example OS has basic drivers for frame buffer, mouse and
  keyboard input, the PCI bus, the real-time clock, and system-specific timers.

:_Server_: The only server in the example OS is Nitpicker, a
  minimal-complexity GUI server.

:_Test_: are also part of the example OS. You may have a look at the fork
  bomb as a simple system stress test.

:_Ldso_: is the dynamic linker used for loading executables that are linked
  against shared libraries.

:_Lib_: contains libraries used by the components of the OS repository,
  for example, the alarm framework.
