Writing specific TLB entries with TLBWI flushes shadow TLB entries
unless an existing entry is having its access permissions upgraded. This
is necessary as software would from then on expect the previous mapping
in that entry to no longer be in effect (even if QEMU has quietly
evicted it to the shadow TLB on a TLBWR).

However it won't do this if only EHINV, XI, or RI bits have been set,
even if that results in a reduction of permissions, so add the necessary
checks to invoke the flush when these bits are set.

Fixes: 2fb58b73 ("target-mips: add RI and XI fields to TLB entry")
Fixes: 9456c2fb ("target-mips: add TLBINV support")

Using MFC0 to read CP0_UserLocal uses tcg_gen_ld32s_tl, however
CP0_UserLocal is a target_ulong. On a big endian host with a MIPS64
target this reads and sign extends the more significant half of the
64-bit register.

Fix this by using ld_tl to load the whole target_ulong and ext32s_tl to
sign extend it, as done for various other target_ulong COP0 registers.

  vnc: Clarify documentation of QMP command change
Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

In various places in our test makefiles and scripts we use the
shell $RANDOM to create a random number. This is a bash
specific extension, and doesn't work on other shells.
With dash the shell doesn't complain, it just effectively
always evaluates $RANDOM to 0:
  echo $((RANDOM + 32768))     => 32768

However, on NetBSD the shell will complain:
  "-sh: arith: syntax error: "RANDOM + 32768"

which means that "make check" fails.

Switch to using "${RANDOM:-0}" instead of $RANDOM,
which will portably either give us a random number or zero.
This means that on non-bash shells we don't get such
good test coverage via the MALLOC_PERTURB_ setting, but
we were already in that situation for non-bash shells.

Our only other uses of $RANDOM (in tests/qemu-iotests/check
and tests/qemu-iotests/162) are in shell scripts which use
a #!/bin/bash line so they are always run under bash.

The current CONFIG_IVSHMEM is confusing, because it looks like it's a
flag for "do we have ivshmem support?", but actually it's a flag for
"is the ivshmem PCI device being compiled?" (and implicitly "do we
have ivshmem support?" is tested with CONFIG_EVENTFD).

Rename it to CONFIG_IVSHMEM_DEVICE to clear this confusion up;
shortly we will add a new CONFIG_IVSHMEM which really does indicate
whether the host can support ivshmem.

glibc now has:

(See https://sourceware.org/bugzilla/show_bug.cgi?id=21457

However, QEMU used "struct ucontext" in declarations. This is a
private name and compatibility cannot be guaranteed. Switch to

QMP command

    { "execute": "change",
      "arguments": { "device": "vnc", "target": "password", "arg": PWD } }

behaves just like

    { "execute": "change-vnc-password",
      "arguments": { "password", "arg": PWD } }

Their documentation differs, however.  According to
change-vnc-password's documentation, "an empty password [...] will set
the password to the empty string", while change's documentation claims
"no future logins will be allowed".  The former is actually correct.
Replace the incorrect claim by a reference to change-vnc-password.

Now we have two qcrypto backends, libiary-backend and afalg-backend,
but which one is faster? This patch add a cipher speed benchmark, it
helps us to measure the performance by using "make check-speed" or
using "./tests/benchmark-crypto-cipher" directly.
