pflash_cfi01/02: support read-only pflash devices

vmstate, memory: decouple vmstate from memory API
Currently creating a memory region automatically registers it forlive migration. This differs from other state (which is enumeratedin a VMStateDescription structure) and ties the live migration codeinto the memory core....

block: Attach non-qdev devices as well
For now, this just protects against programming errors like having thesame drive back multiple non-qdev devices, or untimely bdrv_delete().Later commits will add other interesting uses.
While there, rename BlockDriverState member peer to dev, bdrv_attach()...
pflash_cfi01/pflash_cfi02: convert to memory API
cfi02 is annoying in that is ignores some address bits; we probablywant explicit support in the memory API for that.
In order to get the correct opaque into the MemoryRegion object, theallocation scheme is changed so that the flash emulation code allocates...

Add endianness as io mem parameter
As stated before, devices can be little, big or native endian. Thetarget endianness is not of their concern, so we need to push thingsdown a level.
This patch adds a parameter to cpu_register_io_memory that allows adevice to choose its endianness. For now, all devices simply choose...
pflash_cfi01: add device ID read command
Add support to read manufacturer and device ID. For everything else (eg.lock bits) 0 is returned.

pflash: Buffer block writes
Buffer block writes to avoid flushing every word access onto backingstorage device. This significantly speeds up flash emulation for flashesconnected through an 8 or 16-bit bus combined with backing storage (-pflash).

pflash: Dont open memarea for full IO if already done.
When wcycle is non zero the area is already opened for readable IO.Avoiding the re-registration of the memarea significantly speeds upthe flash emulation. In particular for flashes connected through 8 or...

Flashes connected through an 8 bit bus cannot handle write bufferslarger than 256 bytes.

Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Somethinglike this must be presented on the list first so people can provide input...

Check block driver read error in pflash_cfi0x
If a flash file of size smaller than the flash size is specified inthe -pflash option, the block driver returns error. But thepflash_cfi0x ignores the error. This results in a flash content of allzeroes. And the simulation aborts while executing code....
