This patch re-arranges nitpicker's graphics backend in a more modular
and expandable way. Generalized versions of the 'Canvas',
'Chunky_canvas', and 'Pixel_*' classes have been moved to
'os/include/util/' and 'os/include/os'. The only remaining parts that
are specific to nitpicker's needs are a few drawing functions, each
located in a distinct header at 'os/include/nitpicker_gfx/'.
This patch makes nitpicker's geometry utilities available for the use
by other programs. Thereby, the 'Point', 'Area', and 'Rect' classes
have become templates that take the coordinate type and distance type
as arguments.
Instead of, passing responsibility to manage and dissolve Signal_rpc_member
objects at a corresponding entrypoint to the user, hand over entrypoint's
reference to the constructor, and do it in the constructor resp. destructor
of the class.
Fixes#1022
Users of a File_system_session might want to force a file system
to flush or rather to synchronize its internal cache. A concret
default implementation is provided because not all file systems
maintain an internal cache and are not required to synchronize
caches.
Fixes#1007.
Make 'set_program_var' accessible outside of 'rtld.c'. Also, compile
dynamically linked programs with the '-fPIC' option. Doing not so,
yields to program-global symbols being put in the '.symtab' section
(which can be stripped) only. In order to get access to global
variables from the dynamic linker, the symbols need to reside within
the '.dynsym' section additionally. Hence the '-fPIC'.

* Increase entrypoint stack size for part_blk server,
since it crashes on 64 bit
* Consider packet alignment in bulk buffer size calculation of test-blk-cli
* allow to handle a maximum of packets in parallel
that fits free slots in the ack queue
* stop processing packets, when the driver can't handle
more requests in parallel, and resume packet handling,
when the driver is ready again
Instead of using an additional thread in each Session_component of a
block server, which uses the generic block component and driver classes,
replace it with signal dispatchers.
Ref #113
To support components, which implement the block session's server side
rpc object, and which doesn't write data to their device backend immediately,
an additional synchronization call is needed. Thereby, clients like for
instance a file system can tell these components, when a synchronization is
required.
