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 used to have:

   typedef struct ucontext { ... } ucontext_t;

glibc now has:

   typedef struct ucontext_t { ... } ucontext_t;

(See https://sourceware.org/bugzilla/show_bug.cgi?id=21457
 for detail and rationale for the glibc change)

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

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.

This patch add a hmac speed benchmark, it helps us to
measure the performance by using "make check-speed" or
using "./tests/benchmark-crypto-hmac" directly.

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.
