linux-nat: Add function lwp_is_stepping
Add the function lwp_is_stepping which indicates whether the given LWP
is currently single-stepping. This is a common interface, usable from
native GDB as well as from gdbserver.
gdb/gdbserver/ChangeLog:
* linux-low.c (lwp_is_stepping): New function.
gdb/ChangeLog:
* nat/linux-nat.h (lwp_is_stepping): New declaration.
* linux-nat.c (lwp_is_stepping): New function.
