df7e526582 Rename 32- and 64-bit Intel files from "i386" to "x86" 
This commit renames nine files that contain code used by both 32- and
64-bit Intel ports such that their names are prefixed with "x86"
rather than "i386".  All types, functions and variables within these
files are likewise renamed such that their names are prefixed with
"x86" rather than "i386".  This makes GDB follow the convention used
by gdbserver such that 32-bit Intel code lives in files called
"i386-*", 64-bit Intel code lives in files called "amd64-*", and code
for both 32- and 64-bit Intel lives in files called "x86-*".

This commit only renames OS-independent files.  The Linux ports of
both GDB and gdbserver now follow the i386/amd64/x86 convention fully.
Some ports still use the old convention where "i386" in file/function/
type/variable names can mean "32-bit only" or "32- and 64-bit" but I
don't want to touch ports I can't fully test except where absolutely
necessary.

0b04e52316 link gdbserver against libiberty 
This builds a libiberty just for gdbserver and arranges for gdbserver
to use it.  I've tripped across the lack of libiberty in gdbserver at
least once, and I have seen other threads where it would have been
useful.

01f9f808e2 Add AVX512 registers support to GDB and GDBserver. 
This patch adds support for the Intel(R) Advanced Vector
Extensions 512 (Intel(R) AVX-512) registers.  Native and remote
debugging are covered by this patch.

Intel(R) AVX-512 is an extension to AVX to support 512-bit wide
SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31).
The number of available registers in 32-bit mode is still 8
(XMM0-7, YMM0-7, ZMM0-7).  The lower 256-bits of the ZMM registers
are aliased to the respective 256-bit YMM registers.  The lower
128-bits are aliased to the respective 128-bit XMM registers.

There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit
mode and 64-bit mode.

379a5e2d36 nameless LOAD_DLL_DEBUG_EVENT causes ntdll.dll to be missing 
This is the gdbserver-equivalent of the change made in GDB to handle
the case, in x64 windows version 2012, where the kernel produces
a LOAD_DLL_DEBUG_EVENT where the name of the associated DLL cannot
be determined at that time, and thus has to be processed later.

The visible symptom is that ntdll.dll is missing from the list of
shared libraries known to be mapped by the inferior, with other
side-effects such as failure to unwind through code provided by
that DLL (such as exception handling routines).

gdb/gdbserver/ChangeLog:

	* Makefile.in (safe-ctype.o, lbasename.o): New rules.
	* configure.srv: Add safe-ctype.o and lbasename.o to srv_tgtobj

50681a2705 Allow powerpc-*-lynxos* GDBserver to send register map via XML... 
... back to GDB.  The transfer occurs when GDB sends the
'qXfer:features:read:target.xml' packet.  This allows us to make
sure that GDB and GDBserver use the same register numbering.
This is important on Lynx 178, where GDB selects the rs6000:6000
architecture by default instead of the powerpc:common architecture.

gdb/gdbserver/ChangeLog:

        * configure.srv (powerpc-*-lynxos*): Set srv_xmlfiles.
