835b04ed79 bsd-user: Add stubs for new signal routines
Until the signal support is merged from the bsd-user fork, we need stubs
for cpu_loop_exit_sigsegv and cpu_loop_exit_sigbus to link. These call
abort after logging a message. Since singals aren't supported here
yet, this is sufficient.

6f08c9c531 Revert "elf: Relax MIPS' elf_check_arch() to accept EM_NANOMIPS too"
Per the "P32 Porting Guide" (rev 1.2) [1], chapter 2:

  p32 ABI Overview
  ----------------

  The Application Binary Interface, or ABI, is the set of rules
  that all binaries must follow in order to run on a nanoMIPS
  system. This includes, for example, object file format,
  instruction set, data layout, subroutine calling convention,
  and system call numbers. The ABI is one part of the mechanism
  that maintains binary compatibility across all nanoMIPS platforms.

  p32 improves on o32 to provide an ABI that is efficient in both
  code density and performance. p32 is required for the nanoMIPS
  architecture.

So far QEMU only support the MIPS o32 / n32 / n64 ABIs. The p32 ABI
is not implemented, therefore we can not run any nanoMIPS binary.

Revert commit f72541f3a5 ("elf: Relax MIPS' elf_check_arch() to
accept EM_NANOMIPS too").

See also the "ELF ABI Supplement" [2].

Checking the CFCMSA opcode result with gdb we get 0x60140:

  Breakpoint 1, 0x00000001200037c4 in main ()
  1: x/i $pc
  => 0x1200037c4 <main+52>:  cfcmsa       v0,msa_ir

  (gdb) i r v0
  v0: 0x60140

MSAIR bits 17 and 18 are "reserved" per the spec revision 1.12,
so mask them out, and set MSAIR=0x0140 for the Loongson-3A4000
CPU model added in commit af868995e1.

73053f6228 target/mips: Remove one MSA unnecessary decodetree overlap group
Only the MSA generic opcode was overlapping with the other
instructions. Since the previous commit removed it, we can
now remove the overlap group. The decodetree script forces
us to re-indent the opcodes.

Diff trivial to review using `git-diff --ignore-all-space`.

Note, the format definition could be named @3rf_b (for

class is named '3R', we simply call the format @3r to
ease reviewing the msa.decode file.
However we directly call the trans_msa_3rf() function,
which handles the BYTE-based df field.

7da9623cc0 block/vpc: Add a sanity check that fixed-size images have the right type
The code in vpc.c uses BDRVVPCState->footer.type in various places
to decide whether the image is a fixed-size (VHD_FIXED) or a dynamic
(VHD_DYNAMIC) image. However, we never check that this field really
contains VHD_FIXED if we detected a fixed size image in vpc_open(),
so a wrong value here could cause quite some trouble during runtime.

f3d43dfd9a vmdk: allow specification of tools version
VMDK files support an attribute that represents the version of the guest
tools that are installed on the disk.
This attribute is used by vSphere before a machine has been started to
determine if the VM has the guest tools installed.
This is important when configuring "Operating system customizations" in
vSphere, as it checks for the presence of the guest tools before
allowing those customizations.
Thus when the VM has not yet booted normally it would be impossible to
customize it, therefore preventing a customized first-boot.

The attribute should not hurt on disks that do not have the guest tools
installed and indeed the VMware tools also unconditionally add this
attribute.
(Defaulting to the value "2147483647", as is done in this patch)
