0ab69a2bb8 base: de-duplicate src/lib/base/platform.cc
By splitting the 'init_capability_slab()' implementation to a separate
compilation unit 'capability_slab.cc', base-hw no longer needs a
customized version of 'lib/base/platform.cc'.

3489672bc0 base: remove env_deprecated from thread-start code
This patch replaces the internal use 'env_deprecated()' from the
implementation of the thread API in the base library. It also
replaces the global accessor 'main_thread_cap' by the explicit
propagation of the main-thread's capability to the single point of
use via a new 'init_thread_bootstap' function.

c907e44a02 register framework: read bitfields to fitting uint
* Replaces bool access types with uint8_t access types
* Ensures, that the framework always uses the smalles possible uint type
  for the return value wherever a bitfield is read and returned to the user.

3c5d27506f base: stricter distinction between rx and rwx
This patch restricts 'Region_map::attach_executable' to create read-only
mappings, while offering the option to map the full rights using a new
'attach_rwx' method.

The 'attach_rwx' method is now used by the dynamic linker to explicitly
attach the linker area with full rwx rights. With the old page-fault
handling code, the execute flag was evaluated only for leaf dataspaces,
not for managed dataspaces while traversing region-map hierarchies.
With the new page-fault handling code, the execute bit is downgraded
to no-execute when passing a managed dataspace that is not attached
as executable.

a4c59c03e3 core: rework page-fault resolution
The change "core: allow offset-attached managed dataspaces" addressed a
corner case of the use of nested region maps. Apparently, this change
negatively affects other scenarios (tool_chain_auto).

In order to confidently cover all the differnt situations, this patch
reworks the page-fault resolution code for improved clarity and safety,
by introducing dedicated result types, reducing the use of basic types,
choosing expressive names, and fostering constness.

It also introduces a number of 'print' hooks that greatly ease manual
instrumentation and streamlines the error messages printed by core.
Those messages no longer appear when a user-level page-fault handler
is reistered for the faulted-at region map. So the monitor component
produces less noise on the attempt to dump non-existing memory.

0d5571a820 base: close PD session last when destructing child
This patch moves the destruction of the child's PD session after the
closing of all other sessions because the PD session's role as resource
container might still be needed for orderly reverting the session quotas
when closing the other remaining sessions.

30b70da6c1 base/child.h: Child_policy::with_address_space
This patch replaces the former 'address_space' accessor by a new
'with_address_space' interface that grants access to the region map of
the child's address space, but limits the interface lifetime to the
scope of the caller.

f47c64e246 core: allow offset-attached managed dataspaces
This patch adds the missing application of the region offset to the
resolution of page faults inside managed dataspaces, which resulted in
an unexpected "invalid mapping" message after attaching a managed
dataspace with an offset.

This limitation could be observed during the implementation of the debug
monitor that locally maps a portion of the debugging target's address
space, e.g., a view port of 16 MiB. All traditional uses of managed
dataspaces (e.g., stack area, linker area) happened to attach the
managed dataspaces from their beginning.

ceaa02230e qemu: set default cpu model for x86_64 explicitly
With the update to sel4 and the gcc 12, assembly instructions are generated
and used, like POPCNT. The instruction is available on our native hardware,
but not emulated by the default cpu model necessarily, which leads to
undefined opcode exceptions (Qemu 4.2.1 && seL4). Additionally, the features
of the default Qemu cpu model may vary between Qemu releases and makes it
harder to correlate effects.

11764ed755 core: remove io_mem attachments before destruction
The attachment removal is triggered actually on _ds member destruction time,
but after the io_mem representation for the specific base-<platform> possibly
vanished already during _unmap_local in the ~Io_mem_dataspace. This creates
on base-sel4 several kernel warnings about invalid capabilities.

d59a2b4b38 ldso: fix page fault at IP 0 with GCC 12 on RISC-V
Eliminate the creation of 'Genode::String's before the linker has been
self relocated, because 'Genode::String's will call 'Genode::strlen' on
construction from C-Strings, which has now become a GOT relative call,
while the GOT contains only zeros before relocation -> page fault at
IP 0.

61926ebc07 base: introduce platform_init function
The new 'init_platform' function performs the platform-specific
component-local low-level initialization. It allows for the
differentiation between core and regular components as well as
kernel-dependent peculiarities.

This patch introduces a consistent notion of a 'Platform'. Within core,
the 'Platform' contains the kernel-specific initialization. Outside
core, the platform sets up the interplay with the parent component. In
all cases, the platform is constructed while running on the initial
stack.
