[stgt] [PATCH 0/8] ssc: the on-disk metadata format changes

[FUJITA Tomonori]

This patchset is against the ssc branch in the git tree (I'll merge
all the ssc patches soon).

This patchset includes two major changes to the on-disk metadata
format.

1. guarantees compatibility among various architectures

The previous format didn't consider about the endian and alignment. As
a result, it has no compatibility among various architectures. For
example, you can't move the ssc file created on an x86 box to an
x86_64 box, a ppc box, etc.

2. uses crc to verify the block header

The previous format uses magic number in the block header to verify
it. Instead I use crc for more integrity of metadata files. However,
we still need some work to make sure integrity in an expected event
such as a power failure.
