Make test messages in gdb.mi/mi-var-display.exp unique

When I fix a bug in gdb.mi/mi-var-display.exp, I find its test
messages aren't unique, which makes some confusions for me.

$ cat testsuite/gdb.sum | grep "PASS" | sort | uniq -c | sort -n
...
 2 PASS: gdb.mi/mi-var-display.exp: set format variable bar
 2 PASS: gdb.mi/mi-var-display.exp: set format variable foo
 2 PASS: gdb.mi/mi-var-display.exp: set format variable weird.func_ptr
 2 PASS: gdb.mi/mi-var-display.exp: set format variable weird.func_ptr_ptr
 2 PASS: gdb.mi/mi-var-display.exp: show format variable foo
 3 PASS: gdb.mi/mi-var-display.exp: eval variable foo

This patch is to make test messages in mi-var-display.exp unique.

Remove duplicated code on checking address 0x0 is accessiable

I find some gdb.python tests fail on arm-none-eabi target, because the
tests assume that memory on address 0x is inaccessible.  Some tests
(in gdb.base) are aware of this, so do a "x 0" check first.  However,
the code is copy-n-paste.

This patch is to move the "x 0" check to a procedure in lib/gdb.exp,
and get needed tests call it.  The original code matches pattern
"0x0:\[ \t\]*Error accessing memory address 0x0\r\n$gdb_prompt $", but
I remove it from the new proc is_address_zero_readable, because GDB
doesn't emit such message any more.

Fix PR remote/9053: remove dead code on query packet size

The code becomes dead as GDB evolves.  In 2003, Andrew Cagney post patch
https://sourceware.org/ml/gdb-patches/2003-10/msg00511.html to add target
read/write partial methods.  They support query buffer size when both
OFFSET and LEN is zero, and it was used in avr-tdep.c and kod.c.  Then,
Daniel added target_read_object_alloc and avr-tdep.c switches to use that
in patch https://sourceware.org/ml/gdb-patches/2006-07/msg00009.html
From then on, GDB on longer queries the buffer size, so the code
returning packet size in remote_xfer_partial became dead.

PR 17060 is duplicated of PR 9053, so I mention the latter in the
ChangeLog entry.  Rebuild GDB with this patch.  OK to apply?
I'll mark PR 17060 as duplicated once the patch is applied.

Change ld "notice" interface for better handling of indirect symbols

The main aim of this change was to have non_ir_ref set correctly on
new indirect symbols.  I could have added a "copy" param to the "notice"
function, so that indirect symbols could be created in plugin_notice,
but it seemed cleaner to create indirect syms earlier and pass them
rather than "string" to "notice".

include/
	* bfdlink.h (struct bfd_link_callbacks <notice>): Remove "string"
	param, add "inh".
bfd/
	* coff-aux.c (coff_m68k_aux_link_add_one_symbol): Only call "notice"
	here when not calling the generic add_symbol function.  Formatting.
	Correct handling of indirect symbols.  Update notice call.
	* elflink.c (_bfd_elf_notice_as_needed): Update notice call.
	* linker.c (_bfd_generic_link_add_one_symbol): Create indirect
	symbols early.  Update notice call.  Add comments regarding weak
	symbols vs. indirect.
ld/
	* ldmain.c (notice): Update args.
	* plugin.c (plugin_notice): Likewise.  Follow warning sym link.
	Handle new indirect symbol.
Fix build breakage when ld plugins disabled

	* ldlang.h (struct lang_input_statement_flags): Don't make "reload"
	field conditional on ENABLE_PLUGINS.
	* ldlang.c (open_input_bfds): Expand plugin_should_reload.
	* plugin.h (plugin_should_reload): Delete.
	* plugin.c (plugin_should_reload): Delete.

Remove type directive
