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.
