04b8418b54 Let memcmp correspond to the C standard (fix #628)
By now, the memcmp implementation of Genode's basic string utilities just
returned whether two memory blocks are equal or differ. It gave no hint which
block is greater, or lesser than the other one. This isn't the behaviour
anticipated by implementations that rely on the C standard memcmp, e.g. GCC's
libsupc++, or the nic_bridge's AVL tree implementation.

b7c1404fbf base & core: Use FIFO to queue RM faulters.
By now RM faulters are hold in a LIFO. Thus a starvation problem
occurs on managed dataspaces when multiple threads throw pagefaults
continuously.

7d30ffc907 base: Fix a number of warnings about unused parameters
The warnings are shown if components using the genode base are
compiled with -Wextra -Wall enabled.

Fixes #489.

0c76bc9cfd Add support for specialized session interfaces
This patch introduces principal support for extending session interfaces
with specialized functionality in a clean way. For example, an 'Uart'
interface may implement the 'Terminal' interface but also offers
additional functions for setting the baud rate. A service that
implements the 'Uart' service will then automatically announce both the
'Uart' and 'Terminal' services.

88ac32e3bb Base: New 'memcpy' implementation
Added CPU specific memcpy function ('memcpy_cpu'), which is tried first in
default 'memcpy'. Improved default 'memcpy' to copy eight byte chunks.

66bec10276 Fix bug in MMIO framework and test it
Avoid that members of a inheritor overlay those of the
register- and MMIO-framework.

Beautify register- and MMIO-framework.

693922d789 Support for 64-bit registers in 'util/register.h'
For 64-bit registers we cannot compute MASK and SHIFT values via enums
because enum values are always of type int. But we can use static member
functions instead. Furthermore, the patch fixes the type trait for
64-bit registers. (apparently, this access width was never used so far)

e34adf883c Introduce design pattern for uncopyable objects.
Introduce a new Noncopyable class, one can derive from to mark a class of
objects to be uncopyable. This way the compiler can check for any violations
for you.

7044b264e6 Beautify class names in 'register.h' and 'mmio.h'
Replace 'Reg_array' in 'Genode::Mmio' by 'Register_array' and 'Subreg'
in 'Genode::Register', 'Genode::Mmio::Register'and
'Genode::Mmio::Register_array' by 'Bitfield'.

Update and beautify comments in the according headers and test programs.

e1285335ab Replace 'Subreg_array' with 'Reg_array'.
'Reg_array' contains items whose width can be the width of the register
storage type at a max. Nethertheless they can be smaller and iterate all
subregs that are covered by the item width. The array uses as much
successive instances of its storage type as needed.

The test 'run/util_mmio' also tests these new features heavily.

01bb7536dd Complement test for MMIO framework
The run script 'run/util_mmio.run' runs a test over basic
functionalities of 'Mmio::Register' and 'Mmio::Register::Subreg'. The
test covers the functions 'read' and 'bits', 'set', 'clear' and 'get'.

Inline function in 'Mmio::Register::Subreg' whose definition otherwise
looks ugly.

9329b91aca Extract more generic parts from 'Genode::Mmio'
To accommodate CPU registers, which have a structured layout but don't
depend on a region base address, this patch introduces the generic
'Genode::Register' and 'Genode::Subreg' to 'register.h'.
'Mmio::Register' and 'Mmio::Subreg' inherit from them.

1f75ebe9e5 First version of generic MMIO access framework
The MMIO access framework consists of an abstraction for a contiguous
MMIO area with a base address set dynamically. Within this class 'Mmio'
are declarations for 'Register' and 'Subreg'. These two can be
parameterized statically via template parameters to create arbitrary
MMIO structures.

Whereas 'Register' relies to a POD like subregion of 'Mmio', 'Subreg'
relies to a MMIO region within a specific 'Register' and therefore is
smaller or equal then the storage type of its superior 'Register'.

Furthermore with 'Reg_array' and 'Subreg_array', there exists the
possibility to handle arrays of uniform contiguous registers or subregs
by index. 'Subreg_array' therefore abstracts from the width boundary of
its superior 'Register' and handles a steady distance between its
members in addition. Both also check array size limits.

Related to issue #69.

210eb98598 Support const RPC functions with no arguments
Until now, the RPC framework did not support const RPC functions. Rather
than being a limitation inherent to the concept, const RPC functions
plainly did not exist. So supporting them was not deemed too important.
However, there are uses of RPC interfaces that would benefit from a way
to declare an RPC function as const. Candidates are functions like
'Framebuffer::Session::mode()' and 'Input::Session::is_pending()'.

This patch clears the way towards declaring such functions as const.
Even though the patch is simple enough, the thorough support for
const-qualified RPC functions would double the number of overloads for
the 'call_member' function template (in 'base/include/util/meta.h'). For
this reason, the patch does support const getter functions with no
arguments only. This appears to be the most common use of such
functions.
