package/gdb: add support for gdb 10.x

All patches from gdb 9.2 are kept, except
0006-sim-ppc-Fix-linker-error-with-fno-common.patch which is
upstream. The other patches are rebased to accommodate some code
re-organization in gdb 10.x, especially the move of the gdbserver code
from gdb/gdbserver/ to gdbserver/.

Subject: [PATCH] use <asm/sgidefs.h>
Build fix for MIPS with musl libc
The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
but not by musl. Regardless of the libc, the kernel headers provide
<asm/sgidefs.h> which provides the same definitions, so use that
instead.

Subject: [PATCH] gdbserver: fix build for m68k
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
As for strace [1], when <sys/reg.h> is included after <linux/ptrace.h>,
the build fails on m68k with the following diagnostics:
In file included from ./../nat/linux-ptrace.h:28:0,
from linux-low.h:27,
from linux-m68k-low.c:20:
[...]/usr/include/sys/reg.h:26:3: error: expected identifier before numeric constant
PT_D1 = 0,
^
[...]usr/include/sys/reg.h:26:3: error: expected « } » before numeric constant
[...]usr/include/sys/reg.h:26:3: error: expected unqualified-id before numeric constant
In file included from linux-m68k-low.c:27:0:
[...]usr/include/sys/reg.h:99:1: error: expected declaration before « } » token
};
^
Fix this by moving <sys/reg.h> on top of "linux-low.h".

Subject: [PATCH] nat/fork-inferior: include linux-ptrace.h
To decide whether fork() or vfork() should be used, fork-inferior.c
uses the following test:
#if !(defined(__UCLIBC__) && defined(HAS_NOMMU))
However, HAS_NOMMU is never defined, because it gets defined in
linux-ptrace.h, which is not included by fork-inferior.c. Due to this,
gdbserver fails to build on noMMU architectures. This commit fixes
that by simply including linux-ptrace.h.
This bug was introduced by commit
2090129c36c7e582943b7d300968d19b46160d84 ("Share fork_inferior et al
with gdbserver"). Indeed, the same fork()/vfork() selection was done,
but in another file where linux-ptrace.h was included.
Fixes the following build issue:
../nat/fork-inferior.c: In function 'pid_t fork_inferior(const char*, const string&, char**, void (*)(), void (*)(int), void (*)(), const char*, void (*)(const char*, char* const*, char* const*))':
../nat/fork-inferior.c:376:11: error: 'fork' was not declared in this scope
pid = fork ();
^~~~
../nat/fork-inferior.c:376:11: note: suggested alternative: 'vfork'
pid = fork ();
^~~~
vfork
