Currently, if not specified in "./configure", QEMU_PKGVERSION will be
empty. Write a rule in Makefile to generate a value from "git describe"
combined with a possible git tree cleanness suffix, and write into a new
header.
$ cat qemu-version.h
#define QEMU_PKGVERSION "-v2.6.0-557-gd6550e9-dirty"
Include the header in .c files where the macro is referenced. It's not
necessary to include it in all files, otherwise each time the content of
the file changes, all sources have to be recompiled.

Implement a QIOChannel subclass that supports sockets I/O.
The implementation is able to manage a single socket file
descriptor, whether a TCP/UNIX listener, TCP/UNIX connection,
or a UDP datagram. It provides APIs which can listen and
connect either asynchronously or synchronously. Since there
is no asynchronous DNS lookup API available, it uses the
QIOTask helper for spawning a background thread to ensure
non-blocking operation.

This patch adds loading, stamp checking and initialization of modules.
The init function of dynamic module is no longer directly called as
__attribute__((constructor)) in static linked version, it is called
only after passed the checking of presense of stamp symbol:
qemu_stamp_$RELEASEHASH
where $RELEASEHASH is generated by hashing version strings and content
of configure script.
With this, modules built from a different tree/version/configure will
not be loaded.
The module loading code requires gmodule-2.0.
Modules are searched under
- CONFIG_MODDIR
- executable folder (to allow running qemu-{img,io} in the build
directory)
- ../ of executable folder (to allow running system emulator in the
build directory)
Modules are linked under their subdir respectively, then copied to top
level of build directory for above convinience, e.g.:
$(BUILD_DIR)/block/curl.so -> $(BUILD_DIR)/block-curl.so

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

Now only the qemu_*dir variables will become #defines. The other
directory names aren't used by the C code.
That means the following #defines won't be available in C code anymore:
- CONFIG_QEMU_BINDIR
- CONFIG_QEMU_LIBDIR
- CONFIG_QEMU_INCLUDEDIR
- CONFIG_QEMU_MANDIR
- CONFIG_QEMU_SYSCONFDIR
- CONFIG_QEMU_LIBEXECDIR
The following #defines are going to be kept because they are handled by
the qemu_* block on create_config:
- CONFIG_QEMU_CONFDIR
- CONFIG_QEMU_DATADIR
- CONFIG_QEMU_DOCDIR
This one will be kept because it is set directly by ./configure:
- CONFIG_QEMU_HELPERDIR
This patch keeps the 'prefix=*' (CONFIG_QEMU_PREFIX) pattern because
other variables may use $prefix on their config-host.mak definitions.
The remaining code will be simplified on a further patch.

The generic *dir section will eventually go away and be replaced with
qemu_* section. By now, both sections will be kept, while the variables
get renamed on config-host.mak.
With this patch, a XXXdir variable will become a CONFIG_QEMU_XXXDIR
define, and a qemu_XXXdir variable will become CONFIG_QEMU_XXXDIR as
well (instead of becoming a CONFIG_QEMU_QEMU_XXXDIR define).
Changes v1 -> v2:
- Rebase on top of newer qemu.git changes, that changed

Some locale settings let make fail or create wrong results
because tr '[:lower:]' '[:upper:]' which is used to convert
from lower to upper case depends on the locale.
With locale tr_TR.UTF-8, lower case 'i' is not converted to 'I'.
This results in wrong entries in config-host.h like these ones:
#define CONFIG_QEMU_PREFiX "/usr/local"
#define CONFIG_QEMU_BiNDiR "/usr/local/bin"
This problem was reported by Emre Ersin.
The same problem occurs when configure creates the target specific
files config-target.mak. They get wrong declarations:
TARGET_CRiS=y
TARGET_i386=y
TARGET_MiCROBLAZE=y
TARGET_MiPS64=y
TARGET_MiPS=y
TARGET_UNiCORE32=y
It is sufficient to restrict the conversion to the characters a-z.
Using this explicit range avoids the dependency on the locale
settings and is also shorter.
v2:
POSIX says that 'tr a-z' is unspecified outside of the POSIX
locale, so we must set LC_ALL=C to make sure that we are using
POSIX (hint from Eric Blake, thanks).

We have code for a quite a few block formats. While I trust that all
of these formats are useful at least for some people in some
circumstances, some of them are of a kind that friends don't let
friends use in production.
This patch provides an optional block format whitelist, default off.
If a whitelist is configured with --block-drv-whitelist, QEMU proper
can use only whitelisted formats. Other programs, like qemu-img, are
not affected.
Drivers for formats off the whitelist still participate in format
probing, to ensure all programs probe exactly the same. Without that,
QEMU proper would be prone to treat images with a format off the
whitelist as raw when the image's format is probed.
