714290979a configure: disable clang -Wstring-plus-int warning
Some versions of clang will warn about adding integers to strings:

disas/i386.c:4753:23: error: adding 'char' to a string does not append
      to the string [-Werror,-Wstring-plus-int]
      oappend ("%es:" + intel_syntax);
               ~~~~~~~^~~~~~~~~~~~~~
disas/i386.c:4753:23: note: use array indexing to silence this warning
      oappend ("%es:" + intel_syntax);
                      ^
               &      [             ]

disas/i386.c uses this idiom to to skip a "%" prefix if using intel
rather than AT&T syntax. This seems like a reasonable  thing to do,
and I don't think anybody contributing to QEMU is likely to believe
that '+' is a string concatenation operator in C, so just disable
-Wstring-plus-int.

24cb36a61c configure: Make NPTL non-optional
Now all linux-user targets support building with NPTL, we can make it
mandatory. This is a good idea because:
 * NPTL is no longer new and experimental; it is completely standard
 * in practice, linux-user without NPTL is nearly useless for
   binaries built against non-ancient glibc
 * it allows us to delete the rather untested code for handling
   the non-NPTL configuration

Note that this patch leaves the CONFIG_USE_NPTL ifdefs in the
bsd-user codebase alone. This makes no change for bsd-user, since
our configure test for NPTL had a "#include <linux/futex.h>"
which means bsd-user would never have been compiled with
CONFIG_USE_NPTL defined, and it still is not.

442a59c8dd linux-user: Enable NPTL for OpenRISC
The OpenRISC kernel ignores CLONE_SETTLS in its copy_thread()
implementation, so a cpu_set_tls() implementation is a no-op.
cpu_clone_regs() was setting the syscall return value in the
wrong register -- it is gpr[11], not gpr[2]. With these two
things fixed, we can compile with NPTL enabled.

only needed for broken installs of libfdt. Now that we have submodule
dtc, just ignore these broken installs and prompt for the dtc submodule
install instead. QEMU's local libfdt_env.h is removed accordingly.

Manifests as a bug when building QEMU with modern libfdt. The new
version of libfdt does not compile when QEMUs libfdt_env.h takes
precedence over the hosts.

2a78636bd2 dump: Drop qmp_dump_guest_memory() stub and build for all targets
qmp_dump_guest_memory() calls dump_init() and returns an Error when
cpu_get_dump_info() returns an error, as done by the stub.
So there is no need to have a stub for qmp_dump_guest_memory().

Enable the documentation of the always-present dump-guest-memory command.

That way we can drop CONFIG_HAVE_CORE_DUMP and leave configure
completely out of the picture for target CPU features.

c22d8e0448 memory_mapping: Drop qemu_get_memory_mapping() stub
dump.c:dump_init() never checked for the return code anyway.
If paging is not enabled, it will fall back to an identity map.
If paging is enabled and getting memory mapping list is not
implemented, qemu_get_guest_memory_mapping() will return an error.

Since the targets not implementing memory mapping also don't implement
dump support, we will not reach this code today and can worry about
changing cpu_paging_enabled() default when the need arises.

This allows us to drop CONFIG_HAVE_GET_MEMORY_SUPPORT.

b64ec4e4ad block: add block driver read only whitelist
We may want to include a driver in the whitelist for read only tasks
such as diagnosing or exporting guest data (with libguestfs as a good
example). This patch introduces a readonly whitelist option, and for
backward compatibility, the old configure option --block-drv-whitelist
is now an alias to rw whitelist.

Drivers in readonly list is only permitted to open file readonly, and
returns -ENOTSUP for RW opening.

E.g. To include vmdk readonly, and others read+write:
    ./configure --target-list=x86_64-softmmu \
                --block-drv-rw-whitelist=qcow2,raw,file,qed \
                --block-drv-ro-whitelist=vmdk

If the user specifies a target list themselves, check each entry

would probably eventually end up hitting the uninformative
"ERROR: Unsupported target CPU").

cbc8d595ef configure: remove confusing file manipulation
The configure script had some code to manipulate config-host.ld~ (i.e.,
a common backup filename), comparing it with the newly-generated file.
I believe the sense of the comparison was backwards.

Since it seemed to serve little purpose anyway, remove it to avoid any
confusion.
