Making an xyzdir variable for each directory prepares for the next
patches introducing config-host.h defines and configure options for them.
It also fixes the problem where overriding prefix at "make install"
time did not override it for sysconfdir.
Removes some of the differences between sysconfdir and other variables,
the rest will go away later.

Change code handling mips16-specific branches to use ISA-neutral special
opcodes. Since there are several places where the delay slot
requirements for microMIPS branches differ from mips16 branches, using
opcodes is easier than checking hflags, then checking mips16
vs. microMIPS.

Commit dd4239d657 broke multiboot. It replaced the
instruction "rep insb (%dx), %es:(%edi)" by the binary output of
"addr32 rep insb (%dx), %es:(%di)".
Linuxboot calls the respective helper function in a code16 section. So the
original instruction was automatically translated to its "addr32" equivalent.
For multiboot, we're running in code32 so gcc didn't add the "addr32" which
breaks the instruction.
This patch splits that helper function in one which uses addr32 and one which
does not, so everyone's happy.
The good news is that nobody probably cared so far. The bundled multiboot.bin
binary was built before the change and is thus correct.
Please also put this patch into -stable.

The correct model type wasn't getting added when hotplugging nics with
pci_add.
Testcase: start VM with default nic type. In the qemu_monitor:
(qemu) pci_add auto nic model=virtio
This results in a nic hot-plug of the same nic type as the default.
This was broken in 5294e2c774
Also changes the behaviour where no .init is defined for a
net_client_type. Previously, 0 was returned, which indicated the init
was successful and that 0 was the index into the nd_tables[] array.
Return -1, indicating unsuccessful init, in such a case.

Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64
to perform the move at the proper width, which may elide a REX prefix.
Introduce a TCG_TYPE_REG enumerator to represent the "native width"
of the host register, and to distinguish the usage from "pointer data"
as represented by the existing TCG_TYPE_PTR.

When snapshot handlers are not defined in the format driver, it is
better to call the ones of the protocol driver. This enables us to
implement snapshot support in the protocol driver.
We need to call bdrv_close() and bdrv_open() handlers of the format
driver before and after bdrv_snapshot_goto() call of the protocol. It is
because the contents of the block driver state may need to be changed
after loading vmstate.
