Minor comment reformatting in generic_elf_osabi_sniffer

Comment says it all.  I just felt that putting some new text in
a separate paragraph allowed us to clearly identify the section
about ELFOSABI_NONE, and the part that talks about the new
ELFOSABI_GNU.

gdb/ChangeLog:

        * osabi.c (generic_elf_osabi_sniffer): Minor comment reformatting.

ada-tasks.c: handle known tasks maintained by a simply-linked list.

The mapping between Ada tasks, and the underlying threads is
normally maintained by the GNAT runtime under the known_tasks
array.  For performance reasons, this array is just a static
array with 10_000 entries in it. However, this is not very
practical in certain environments where memory is limited.
For those environments, the runtime has been enhanced to use
an alternate scheme with a linked list.

This change enhances the Ada tasking support to recognize this
situation and use the correct way of reading the tasks info
based on the the situation.

gdb/ChangeLog  (Tristan Gingold)

* ada-tasks.c (KNOWN_TASKS_LIST): New macro.
(tcb_fieldno): Add activation_link field.
(get_known_tasks_addr): Moved and rewritten.
(get_tcb_types_info): Set activation_link field.
(read_known_tasks_array): Add parameter.  Rewritten.

(read_known_tasks): New function.
(ada_build_task_list): Call read_known_tasks instead of
read_known_tasks_array.

(has_ravenscar_runtime): Check for task list too.

Minor changes in ada-tasks.c

Do not load .eh_frame section from separete object files

We don't need to read the .eh_frame section from the separate
object files, because this data is already present in the
main executable (it needs to, or the program wouldn't work).

We discovered this investigating a problem with the 'next' command,
which was due to unwind failures, which came from the fact that
the .eh_frame was incorrectly relocated.

gdb/ChangeLog (Tristan Gingold):

    * dwarf2-frame.c (dwarf2_build_frame_info): Do not load .eh_frame
    section in separate object files.

Throughout, open console handles with sharing for reading and writing.
* dcrt0.cc (insert_file): Open file with full sharing allowed.
* hookapi.cc (find_first_notloaded_dll): Ditto.
* spawn.cc (av::fixup): Ditto.

gdb/
Fix false GCC warning.
* linespec.c (decode_line_1): Initialize values.

* dtable.cc (dtable::init_std_file_from_handle): Change test for console
device in call to fh->init to avoid conhost crash on W7.

* environ.cc (environ_init): Reinstantiate on-the-fly CYGWIN variable
test and call to parse_options if found.

* fhandler.cc (fhandler_base::open_with_arch): Call close_on_exec last to avoid
setting close_on_exec for archetype.
* fhandler_tty.cc (fhandler_pty_master::setup): Protect {from,to}_pty handles.
Use consistent naming in debug output.  Use inheritable handles and...
(fhandler_pty_master::fixup_after_fork): ...avoid duplicating handles here.
(fhandler_pty_slave::open): Don't set close_on_exec flag here.
