bdb917bf8a virtio-serial: allocate post_load only at load-time
This saves us a few bytes in the VirtIOSerial struct.  Not a big
savings, but since the entire structure is used only during a short
while after migration, it's helpful to keep the struct cleaner and
smaller.

e49d021e57 configure: Default to 'cc', not 'gcc'
Default to 'cc' as our compiler, rather than 'gcc'. We used to have
to insist on gcc when we still kept the CPU env in a fixed global
register, but this is no longer necessary and we will now compile OK
on clang as well as gcc.  Using 'cc' should generally result in us
using the most standard and maintained system compiler for the
platform.  (For instance on newer MacOS X 'gcc' exists but is an
elderly compiler provided mostly for legacy reasons, and 'cc'
(which is clang) is definitely the better choice.) On Linux there
will generally be no user-visible change since cc will be gcc.

This changeover necessitates a slight reworking of how we set the
'cc' variable, because GNU cross toolchains generally provide a
'${cross_prefix}gcc' but not a '${cross_prefix}cc'.

24c35a504e linux-user: Merge pread/pwrite into pread64/pwrite64
The Linux syscalls underlying pread() and pwrite() take a 64 bit
offset on all architectures, even if some of them name the syscall
"pread/pwrite" rather than "pread64/pwrite64" for historical reasons.
So move the four QEMU target architectures (arm, i386, sparc,
unicore32) which were defining TARGET_NR_pread/pwrite to define
TARGET_NR_pread64/pwrite64 instead, and drop the TARGET_NR_pread/pwrite
implementation code completely.

(Based on examination of the kernel sources for the four architectures
this patch affects.)

Now that QEMU 1.3 was released, we can finally kill the support for
cpudef config sections, and support only the built-in CPU models from
target-i386/cpu.c.

8f961357d0 target-i386: Separate feature string parsing from CPU model lookup
Instead of parsing the whole cpu_model string inside
cpu_x86_find_by_name(), first split it into the CPU model name and the
full feature string, then parse the feature string into pieces.

When using CPU model classes, those two pieces of information will be
used at different moments (CPU model name will be used to find CPU
class, feature string will be used after CPU object was created), so
making the split in two steps will make it easier to refactor the code
later.

This should also help on the CPU properties work, that will just need to
replace the cpu_x86_parse_featurestr() logic (and can keep the CPU model
lookup code as-is).

Replace it with an error_report() call, followed by abort().

This will also help reduce dependencies of the qdev code (as hw_error()
is from cpus.o, and depends on the CPU list from exec.o).
