This patch will use QemuOpts related functions in block layer, add
a member bdrv_create_options to BlockDriver struct, it will return
a QemuOptsList pointer, which includes the image format's create
options.
And create options's primary consumer is block creating related functions,
so modify them together.
This patch also define a macro called STRINGIZER, it is used to convert
number to string.
v6->v7:
1) use osdep.h:stringify(), not redefining new macro.
2) preserve TODO comment.
3) fix typo: BLOCK_OPT_ENCRYPT->BLOCK_OPT_STATIC.
4) initialize disk_type even when opts is NULL.
v5->v6:
1) judge if opts == NULL in block layer create functions.
2) use bdrv_create_file(filename, NULL) in qcow_create and cow_create funtion.
3) made more readable while using qemu_opt_get_number.
