target-xtensa: add missing window check for entry

Entry opcode needs to check if moving to new register frame would cause
register window overflow. Entry used in function prologue never
overflows because preceding windowed call* opcode writes return address
to the target register window frame, causing overflow exceptions at the
point of call. But when a sequence of entry opcodes is used for register
window spilling there may not be a call or other opcode that would cause
window check between entries and they would not raise overflow exception
themselves resulting in data corruption.

slirp/smbd: modify/set several parameters in generated smbd.conf

The file sharing module should not handle printers, so disable it.
The options 'load printers' and 'printing' have been available since the
beginning (May 1996, commit 0e8fd3398771da2f016d72830179507f3edda51b).
Option 'disable spoolss' is available since Samba 2.0.4, commit
de5f42c9d9172592779fa2504d44544e3b6b1c0d).

Next, "socket address" was reported as deprecated, use a combination of
"interfaces" and "bind interfaces only" instead (available since October
1997, commit 79f4fb52c1ed56fd843f81b4eb0cdd2991d4d0f4).

Override cache directory to avoid writing to a global directory. Option
available since Samba 3.4.0, Jan 2009, commit
19a05bf2f485023b11b41dfae3f6459847d55ef7.

Set "usershare max shared=0" to prevent a global directory from being
used. Option available since Samba 3.0.23, February 2006, commit
5831715049f2d460ce42299963a5defdc160891b.

The last option was introduced with Samba 3.4.0, but previously
"state directory" was already added which exists in Samba 3.4.0. As
unknown parameters are ignored (while printing a warning), it should be
safe to add another option.

gdbstub: Add a missing case of signal number translation in gdbstub

While using qemu with gdb "target remote" to debug an application that uses
fork and exec, the qemu process receives SIGSTOP every time the forked process
terminates (sending SIGCHLD).

This is caused by a missing call to gdb_signal_to_target in gdbstub.c, which
is fixed by this patch:

pc-bios: petalogix-s3adsp1800.dtb: Use 'xlnx, xps-ethernetlite-2.00.a' instead of 'xlnx, xps-ethernetlite-2.00.b'

For Linux upstream kernel (e.g. 3.17-rc7), the related compatible string
'xlnx,xps-ethernetlite-2.00.a' is supported, but 'b' is not supported,
so change qemu dtb file to match kernel driver.

The related operation for qemu (after this patch):

   yum install libvirt
   yum install tunctl
   tunctl -b
   ip link set tap0 up
   brctl addif virbr0 tap0

   ./configure
   make
   ./microblaze-softmmu/qemu-system-microblaze -M petalogix-s3adsp1800 \
     -kernel ../linux-stable.microblaze/arch/microblaze/boot/linux.bin \
     -no-reboot -append "console=ttyUL0,115200 doreboot" -nographic \
     -net nic,vlan=0,model=xlnx.xps-ethernetlite,macaddr=00:16:35:AF:94:00 \
     -net tap,vlan=0,ifname=tap0,script=no,downscript=no

   in microblaze qemu bash (guest machine):

     ifconfig eth0 add 192.168.122.2 netmask 255.255.255.0
     ifconfig eth0 up

   Then can telnet 192.168.122.2 directly without password from the host
   machine.

The related operation for generating new dtb:

   building Linux kernel firstly, then get dts tool "./scripts/dts/dts".
   "./scripts/dtc/dtc -I dtb -O dts  -o ../work.dts ../qemu/petalogix-s3adsp1800.dtb"
   edit work.dts (replace 'xlnx,xps-ethernetlite-2.00.b')
   "./scripts/dtc/dtc -I dts -O dtb  -o ..qemu/petalogix-s3adsp1800.dtb ../work.dts"

(Since I am not quite sure whether can read this patch or not, I put the
related dtb file in attachment, please check, thanks).

linux-user: Fix up timer id handling

When creating a timer handle, we give the timer id a special magic offset
of 0xcafe0000. However, we never mask that offset out of the timer id before
we start using it to dereference our timer array. So we always end up aborting
timer operations because the timer id is out of bounds.

This was not an issue before my patch e52a99f756e ("linux-user: Simplify
timerid checks on g_posix_timers range") because before we would blindly mask
anything above the first 16 bits.

This patch simplifies the code around timer id creation by introducing a proper
target_timer_id typedef that is s32, just like Linux has it. It also changes the
magic offset to a value that makes all timer ids be positive.

coroutine-sigaltstack: Change jmp_buf to sigjmp_buf

This is a simple patch to change the type of old_env from jmp_buf
to sigjmp_buf.  old_env is used by sigsetjmp and as such should be
a sigjmp_buf.

This fixes a stack_chk fail in a OSX 32bit build. Since at least on
OSX sigjmp_buf is four bytes larger then a jmpbuf, resulting in an
overflow in sigsetjmp. Due to variable reordering this overwrites
the stack cookie.
