511acad507 Consolidate RM service into PD session
This patch integrates three region maps into each PD session to
reduce the session overhead and to simplify the PD creation procedure.
Please refer to the issue cited below for an elaborative discussion.

Note the API change:

With this patch, the semantics of core's RM service have changed. Now,
the service is merely a tool for creating and destroying managed
dataspaces, which are rarely needed. Regular components no longer need a
RM session. For this reason, the corresponding argument for the
'Process' and 'Child' constructors has been removed.

The former interface of the 'Rm_session' is not named 'Region_map'. As a
minor refinement, the 'Fault_type' enum values are now part of the
'Region_map::State' struct.

e20bbe7002 base: remove integer return codes from PD-session
The return code of assign_parent remained unused. So this patch
removes it.

The bind_thread function fails only due to platform-specific limitations
such as the exhaustion of ID name spaces, which cannot be sensibly
handled by the PD-session client. If occurred, such conditions used to
be reflected by integer return codes that were used for diagnostic
messages only. The patch removes the return codes and leaves the
diagnostic output to core.

The mixer is not directly necessary for the avplay demo. But it implies

463b39fc73 xml reporter: support different start node name
Currently the report name is used implicitly as first xml node name for the

reports under various names (e.g. to steer consumers/clients slightly
differently) but with the same xml node tree structure.

cba6f5f298 base: no exit handler for libc stdout log console

4ef2b0ed2e hw arm: avoid shared cache lines during MP init
When bringing up the kernel on multiple cores, there is a time span
where some cores already have caches enabled and some don't. Core-local
storage that may be used during this time must be aligned at least to
the maximum line size among global caches. Otherwise, a cached core may
unintentionally prefetch data of a yet uncached core into a global
cache. This may corrupt the view of the uncached core as soon as it
enables caches. However, to determine the exact alignment for every
single ARM platform isn't sensible. Instead, we can align to the minimum
page size assuming that a cache never wants to prefetch from multiple
pages at once and thus fulfills "line size <= page size".

a96130f20b base: get rid of alloc align default value
When using the Allocator interface, one can't tell which alignment
resulting allocations fulfill. However, at least on ARM, given the
architectural alignment requirements of ARM memory accesses, one wants
memory allocations (what allocators are for in most cases) to be word
aligned automatically. Previously, at least the AVL allocator simply
called alloc_aligned without defining align in its alloc implementation.
This led to unaligned access faults (the default was 0) when using the
AVL allocator as Allocator (as done in the metadata management of a SLAB
of an AVL that uses the AVL as backing store). To avoid such pitfalls
in the future, we force users of alloc_aligned to always specify align
(why use alloc_aligned without align anyway).

5b12034531 hw_zynq: refactor specs
This is a generalisation approach of the hw_zynq target. As the boards
typically use UART1 instead of UART0 (used by qemu), we have to
distinguish between those. Moreover, in general hw_zynq does not imply
zynq_qemu anymore, so that the support of particular boards can be
placed in third-party or community repositories (e.g. Genode world).

f186587cab Unify ipc_msgbuf.h across base platforms
Besides unifying the Msgbuf_base classes across all platforms, this
patch merges the Ipc_marshaller functionality into Msgbuf_base, which
leads to several further simplifications. For example, this patch
eventually moves the Native_connection_state and removes all state
from the former Ipc_server to the actual server loop, which not only
makes the flow of control and information much more obvious, but is
also more flexible. I.e., on NOVA, we don't even have the notion of
reply-and-wait. Now, we are no longer forced to pretend otherwise.

0c299c5e08 base: separate native CPU from CPU session
This patch unifies the CPU session interface across all platforms. The
former differences are moved to respective "native-CPU" interfaces.

NOVA is not covered by the patch and still relies on a custom version of
the core-internal 'cpu_session_component.h'. However, this will soon be
removed once the ongoing rework of pause/single-step on NOVA is
completed.

e9dec93f4b base: optimized slab allocator
This patch changes the organization of the slab blocks within the slab
allocator. Originally, blocks were kept in a list sorted by the number
of free entries. However, it turned out that the maintenance of this
invariant involves a lot of overhead in the presence of a large number
of blocks. The new implementation manages blocks within a ring in no
particular order and maintains a pointer to the block where the next
allocation is attempted. This alleviates the need for sorting blocks
when allocating and deallocating.

7cf40a0971 allocator_avl: hand back meta data when destructed
This patch ensures that the 'Allocator_avl' releases all memory obtained
from the meta-data allocator at destruction time. If allocations are
still dangling, it produces a warning, hinting at possible memory leaks.
Finally, it properly reverts all 'add_range' operations.

ed37c2ecff core: use copy of region metadata in detach
This patch fixes a use-after-free problem raised by the recent ability of
the slab allocator to dynamically release empty slab blocks. The
Rm_session_component::detach function used to rely on the assumption
that the region metadata co-located with the allocator metadata of the
'_map' would stay intact even after a 'free' if the region.

329ab80d1d libc: never destruct the file-descriptor allocator

8971bb25ce heap: release ds pool meta data when destructed
This patch makes sure that the dataspace pool is flushed before
destructing the heap-local allocator-avl instance. With the original
destruction order, the allocator would still contain dangling
allocations on the account of the dataspace pool when destructed. In
practice, this caused no problem because the underlying backing store is
eventually freed on the destruction of the pool. But it triggers a
runtime warning of the allocator since it has become more strict with
regard to dangling allocations.

357dbdd64b sel4: allocate vm-space meta data statically
This patch removes the dynamically growing slab allocator from the
page-table registry. This has two benefits. First, we alleviate the
corner cases where the slab allocator needed to extend its backing store
while establishing a core-local memory mapping, thereby triggering a
nested core-local mapping. Without this corner case, no reentrant lock
is needed any longer. Second, it removes the dependency from the overly
large old API of the slab allocator. So we can tighten the slab
interface.
