618b83499c base: bug in copy constructor of Signal
The copy constructor of Signal did not copy the Signal::Data contents of
the copy source. This bug could survive undetected because the compiler
can optimize code in a way, that copy constructor and destructor are not
necessary when returning by value from simple functions. I assume that
it creates the object in CPU registers instead of RAM and reuses it
instead of copying it to save time. This way the bug triggered first
after wait_for_signal was changed in a way that avoided optimization.

5befab7f3d Add 'String<SIZE>' buffer type to 'util/string.h'
The new 'String' buffer type is meant to replace the manually created
character buffers that are scattered throughout Genode. It plainly holds
a null-terminated string to be stored as a member variable (e.g., a
session label) or passed as RPC argument. It is not intended to become a
string API.

f763e5ec2a Move main bootstrap to platform-specific object
To prevent multiple execution of main-bootstrap, I moved the code to a
statically initialized object. The reason for this change is that
_main() is exeuted twice when starting dynamic binaries. Now, the object
is part of the base-common library which is linked with ld.lib.so.

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.

2501cb189e core: explicitly throw Out_of_metadata
In case there is not enough quota left to create the trace buffer
or trace policy dataspace throw Out_of_metadata explicitly instead
of rethrowing the Ram_session::Quota_exceeded exception. Now one
can catch Trace::Out_of_metadata exception in a client application.

In addition fix Allocator_guard::withdraw() checks because this
method does not throw any exceptions and a failed withdrawal goes
unoticed.

Fixes #871.

bb00aebc9e hw & signal: consider initial SLAB blocks
By now Signal_session_component has allocated initial SLAB
blocks in constructor, wich crashed with the root
components assumptions about the RAM quota needs of
session creation. Thus, if the background allocator was already
exhausted from component allocation the session was created
with broken initial SLAB blocks.
