copy/paste typo when registering the `show ravenscar' prefix command

gdb/ChangeLog:

        * ravenscar-thread.c (_initialize_ravenscar): Fix copy/paste typo
        in name of "show ravenscar" prefix command name.

Add missing \n in `show ravenscar task-switching' output

A new-line was missing at the end of the output of the `show ravenscar
task-switching' command.  For instance:

    (gdb) show ravenscar task-switching
    Support for Ravenscar task/thread switching is enabled(gdb)

This patch fixes it.

gdb/ChangeLog:

        * ravenscar-thread.c (show_ravenscar_task_switching_command):
        Add missing '\n' in output.

[Ada/ravenscar] New name for active-thread symbol

The GNAT Ravenscar implementation has recently been enhanced to allow
programs using that runtime to run on multi-cpu systems.  One of the
changes that were made is that the name of the symbol we use to
determine which task is the currently-running task has changed.

This patch enhances the debugger to use the new name, and fallback on
the old name if not found (this is for compatibility with older versions
of the compiler/runtime).

gdb/ChangeLog:

        * ravenscar-thread.c (running_thread_name): Change value.
        (read_thread_id): Remove advance declaration.
        (get_running_thread_msymbol): New function.
        (has_ravenscar_runtime): Use get_running_thread_msymbol to
        compute msym_running_thread.
        (get_running_thread_id): Renames read_thread_id. Slight modifications
        to not take any argument anymore, using get_running_thread_msymbol
        to determine which symbol to use instead.
        (ravenscar_running_thread): Use get_running_thread_id instead of
        read_thread_id.

Move ChangeLog entry to the correct ChangeLog file.

bfd: bfin: drop needless symbol flag handling imported from FRV

The Blackfin bfd merged some FRV code recently, and then removed pieces
that didn't make sense.  In the FRV code, it outputs a "_gp" symbol in
its BFD whereas in the Blackfin code, we don't.  So while on the FRV
side it fiddles with the "flags" variable (sometimes using it for section
flags and sometimes using it for symbol flags), we don't need any of
that.  This lead to BZ 12177 where the Blackfin code is a bit confusing.
So to fix things up, remove more stuff we don't need.  Shouldn't change
the behavior at all.
