Instead of passing a pointer to memory now just extend the GByteArray
to all the read register helpers. They can then safely append their
data through the normal way. We don't bother with this abstraction for
write registers as we have already ensured the buffer being copied
from is the correct size.

This is cleaner than poking memory directly and will make later
clean-ups easier.

gdb-xml/i386-32bit.xml includes the k_gs_base register too, so we have to
handle it even if TARGET_X86_64 is not defined. This is already done in
x86_cpu_gdb_read_register, but not in x86_cpu_gdb_write_register where the
incorrect return value causes all registers after it to be clobbered.

The machine description we send is being (silently) thrown on the floor
by GDB and GDB silently uses the default machine description, because
the xml parse fails on <feature> nested within <feature>.
Changes to the xml in qemu source code have no effect.
In addition, the default machine description has fs_base, which fails to
be retrieved, which breaks the whole register window. Add it and the
other control registers.

The remote protocol can't handle flipping back and forth
between 32-bit and 64-bit regs. To compensate, pretend "as if"
on 64-bit cpu when in 32-bit mode.

We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
