fc11e26511 core: pass ram, rm, io-ports to local services
This patch replaces the use of 'core_env()' in 'platform_services.cc' by
the function arguments 'core_ram', 'core_rm', and 'io_port_ranges'.

It also removes the 'Pd_session' argument from 'Io_port_root' and
'Irq_root' to avoid the reliance on the 'Pd_session' interface within
core,

43d7c3bd11 core: don't rely on Core_env in platform.cc
Replace the use of the global 'core_env()' accessor by the explicit
delegation of interfaces.

- For allocating UTCBs in base-hw, 'Platform_thread' requires
  a way to allocate dataspaces ('Ram_allocator') accounted to the
  corresponding CPU session, a way to locally map the allocated
  dataspaces (core's 'Region_map'), and a way to determine the
  physical address (via 'Rpc_entrypoint') used for the initial
  UTCB mapping of main threads. Hence those interfaces must be
  passed to 'Platform_thread'.

- NOVA's pager code needs to look up 'Cpu_thread_component'
  objects using a map item as key. The lookup requires the
  'Rpc_entrypoint' that hold the 'Cpu_thread_component' objects.
  To make this 'Rpc_entrypoint' available, this patch adds
  the 'init_page_fault_handing' function.

- The 'Region_map_mmap' for Linux requires a way to look up
  'Linux_dataspace' objects for given dataspace capabilities.
  This lookup requires the 'Rpc_entrypoint' holding the dataspaces,
  which is now passed to 'platform.cc' via the new Linux-specific
  'Core_region_map::init' function.

5e3a898109 base: add create_vcpu to Vm_session interface
`Vm_session_component::create_vcpu()` is present across all supported
kernels, yet until now it was not part of the `Vm_session` interface.

Add the method to the `Vm_session` interface. This unifies calls in the
base library and is the basis to remove the need for a common base class
for separate `Vm_session` implementations for SVM and VMX on x86_64.

d44ec53cd3 core: tie Platform_thread to Platform_pd
This patch tightens the coupling of the 'Platform_thread' objects
with their corresponding 'Platform_pd' objects by specifying the
'Platform_pd' as constructor argument, keeping the relationship
as a reference (instead of a pointer), and constraining the
lifetime of 'Platform_pd' objects to the lifetime of the PD.

It thereby clears the way to simplify the thread creation since all
PD-related information (like quota budgets) are now known at the
construction time of the 'Platform_thread'.

The return value of 'Platform_thread::start' has been removed because it
is not evaluated by 'Cpu_thread_component'.

d866b6b053 Remove exceptions from Cpu_session interface
The 'Thread_creation_failed' error is now reflected as

eefaa07024 base: add irq_type session argument
By adding the `irq_type` argument, one can explicitly specify whether to
use LEGACY, MSI or MSI-X interrupts. We formerly used the
`device_phys_config` to implicitly select MSI, however, with the
addition of IOMMU support to the platform driver there is at least one
instance where we need an MSI for a non-PCI device.

Yet, by adding another session argument to the Irq session, we exceed
the character limit for session args. Since not all arguments are
relevant for LEGACY interrupts resp. MSI, we can split the Irq_connection
constructor to handle the two cases separately and omit unneeded
arguments.

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.

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.

2e6dd010ae core: introduce 'Core' namespace
The namespace draws a clear line between the base library and the core
component.

It is declared at the new core-local header <types.h>, which is expected
to be included by all code of the core component. It is thereby a
natural place for kernel-agnostic general types like commonly used C++
utilities.

dc39a8db62 base: introduce Allocator::try_alloc
This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.

To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.
