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".

* bfdlink.h (struct bfd_link_callbacks <notice>): Remove "string"
param, add "inh".

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.

* remote.c (remote_xfer_partial): Remove dead code.
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.

Also rewrite the 'supply_regset' method, making it platform
independent. To avoid code duplication, move the logic for both to a
register map in regcache_map_entry format.
In order to provide 'collect_regset' support, the generic function
regcache_collect_regset is exploited. Since this requires writing
appropriate register maps, these can be used for supply_regset as
well.
Rather than supplying own supply/collect functions, use the generic
functions regcache_supply_regset and regcache_collect_regset instead.
The register maps are rewritten accordingly and become much shorter
(and better readable) than before.
These functions are intended to suit all targets that don't require too
special logic in their regset supply/collect methods. Having such
generic functions helps reducing target-specific complexity.
The regset structure's 'descr' field is intended to represent some
kind of "register map". Thus, before making more use of it, this
change renames it to 'regmap' and adjusts the comment appropriately.

This commit moves the inclusion of errno.h to common-defs.h and
removes all other inclusions. Note that prior to this commit
server.h included errno.h protected by "#ifdef HAVE_ERRNO_H".
This protection was added with the Windows CE port, which is
currently broken. Since no other platform needs this, I have
removed the protection and the configury to support it.
