partition: include partuuid string in debug string ...

When debugging partitions detected by barebox, knowing the partuuid
can be useful. Include it in the dev_dbg output.

of: partitions: flag partitions from a partition table ...

We are going to call the of_partition_fixup for regular block
devices like MMC/SD aswell. Add a flag to partitions indicating
they are instanciated from a on-disk partition table so that they
won't be added as device tree partitions during fixup.

string: Fix (v)asprintf prototypes ...

Our asprintf and vasprintf have different prototypes than the glibc
functions. This causes trouble when we want to share barebox code
with userspace code. Change the prototypes for (v)asprintf to match
the glibc prototypes. Since the current (v)asprintf are convenient
to use change the existing functions to b(v)asprintf.

partition: Create links with partition names ...

When a partition has a name create a link to the original partition
rather than registering a second cdev.

cdev: Add partuuid string to struct cdev ...

This adds the partuuid string to struct cdev in order to have this
available for constructing a suitable Linux root=PARTUUID= option
for booting Linux.

common: fix mbr filetype detection ...

Sometimes mbr is erroneously recocognised as FAT partion. Due to this the mbr
partition parser is not being called and the partitions on the media are not
detected. This patch should  fix the problem. The checking is done as in the
linux kernel.

I have seen the problem using usb sticks. Although partitioning and formatting
them under linux. The file system type field in the mbr remains there which
causes the wrong detections as FAT32 type and not as mbr.

block: implement block_read/block_write functions ...

Some drivers use blk->ops->read/write. This bypasses the caching block
layer and was never intended like this. The upper API to the block layer
is the cdev layer. This patch adds block_read and block_write functions
and uses them where appropriate.

common/partition: check only for partition table types ...

The detection of the partition table fails when we have a barebox image
in the MBR. So check only for partition table types.
