Joel Brobecker 42a4f53d2b Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

Pedro Alves 66b4deae03 target_ops::to_stratum -> target_ops::stratum() virtual method
Given that a target's stratum is a property of the type, and not of an
instance of the type, get rid of to_stratum data field and replace it
with a virtual method.

I.e., when we have e.g., 10 target remote instances active, there's no
need for each of the instances to have their own to_stratum copy.

Pedro Alves f3d11a9a96 Convert default_child_has_foo functions to process_stratum_target methods
This patch converts the default_child_has_foo functions to
process_stratum_target methods.  This simplifies "regular"
non-inf_child process_stratum targets, since they no longer have to
override the target_ops::has_foo methods to call the default_child_foo
functions.  A couple targets need to override the new defaults
(corelow and tracefiles), but it still seems like a good tradeoff,
since those are expected to be little different (target doesn't run).

Pedro Alves 3b3dac9b3f Introduce process_stratum_target
This adds a base class that all process_stratum targets inherit from.

default_thread_address_space/default_thread_architecture only make
sense for process_stratum targets, so they are transformed to
process_stratum_target methods/overrides.
