Norman Feske 5ed5fddb7c base/os: remove deprecated APIs
This commit removes APIs that were previously marked as deprecated. This
change has the following implications:

- The use of the global 'env()' accessor is not possible anymore.
- Boolean accessor methods are no longer prefixed with 'is_'. E.g.,
  instead of 'is_valid()', use 'valid()'.
- The last traces of 'Ram_session' are gone now. The 'Env::ram()'
  accessor returns the 'Ram_allocator' interface, which is a subset of
  the 'Pd_session' interface.
- All connection constructors need the 'Env' as argument.
- The 'Reporter' constructor needs an 'Env' argument now because the
  reporter creates a report connection.
- The old overload 'Child_policy::resolve_session_request' that returned
  a 'Service' does not exist anymore.
- The base/printf.h header has been removed, use base/log.h instead.
- The old notion of 'Signal_dispatcher' is gone. Use 'Signal_handler'.
- Transitional headers like os/server.h, cap_session/,
  volatile_object.h, os/attached*_dataspace.h, signal_rpc_dispatcher.h
  have been removed.
- The distinction between 'Thread_state' and 'Thread_state_base' does
  not exist anymore.
- The header cpu_thread/capability.h along with the type definition of
  'Cpu_thread_capability' has been removed. Use the type
  'Thread_capability' define in cpu_session/cpu_session.h instead.
- Several XML utilities (i.e., at os/include/decorator) could be removed
  because their functionality is nowadays covered by util/xml_node.h.
- The 'os/ram_session_guard.h' has been removed.
  Use 'Constrained_ram_allocator' provided by base/ram_allocator.h instead.
