cfe5f01104 pflash_cfi01/pflash_cfi02: convert to memory API
cfi02 is annoying in that is ignores some address bits; we probably
want explicit support in the memory API for that.

In order to get the correct opaque into the MemoryRegion object, the
allocation scheme is changed so that the flash emulation code allocates
memory, instead of the caller.  This clears a FIXME in the flash code.

541dc0d47f Use new macro QEMU_PACKED for packed structures

git grep -la '__attribute__((packed))'|xargs perl -pi -e 's/__attribute__\(\(packed\)\)/QEMU_PACKED/'
git grep -la '__attribute__ ((packed))'|xargs perl -pi -e 's/__attribute__ \(\(packed\)\)/QEMU_PACKED/'
git grep -la '__attribute__((__packed__))'|xargs perl -pi -e 's/__attribute__\(\(__packed__\)\)/QEMU_PACKED/'

git grep -la '__attribute((packed))'|xargs perl -pi -e 's/__attribute\(\(packed\)\)/QEMU_PACKED/'

Whitespace in linux-user/syscall_defs.h was fixed manually
to avoid warnings from scripts/checkpatch.pl.

Manual changes were also applied to hw/pc.c.

I did not fix indentation with tabs in block/vvfat.c.
The patch will show 4 errors with scripts/checkpatch.pl.

0f7fdd3475 Add new macro QEMU_PACKED for packed C structures
A packed struct needs different gcc attributes for compilations
with MinGW compilers because glib-2.0 adds compiler flag
-mms-bitfields which modifies the packing algorithm.

Attribute gcc_struct reverses the negative effects of -mms-bitfields.
QEMU_PACKED sets this attribute and must be used for any packed
struct which is affected by -mms-bitfields.

Fix install(1) usage to be compatible with OpenBSD's install(1).

When creating a directory via the -d flag the -p flag cannot be

doesn't make sense to use the -p flag anyway so use the [default]
-c flag instead.

12d4536f7d main: force enabling of I/O thread
Enabling the I/O thread by default seems like an important part of declaring
1.0.  Besides allowing true SMP support with KVM, the I/O thread means that the
TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which
currently requires a (racey) signal based alarm system.

I know there have been concerns about performance.  I think so far the ones that
have come up (virtio-net) are most likely due to secondary reasons like
decreased batching.

I think we ought to force enabling I/O thread early in 1.0 development and
commit to resolving any lingering issues.
