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. Issue #1987
