On legacy kernels with ROM devices, we can get mtdinfo errors like:
libmtd: error!: cannot open "/dev/mtd4"
error 13 (Permission denied)
mtdinfo: error!: libmtd failed get MTD device 4 information
error 13 (Permission denied)
We don't need O_RDRW access for informational ioctls(), so make this
O_RDONLY.

Implement the 'legacy_dev_present()' function which will check whether an MTD
device is present by scanning the /proc/mtd file when the MTD subsystem does
not support sysfs (the case for pre-2.6.30 kernels).
This patch also moves the 'mtd_dev_present()' function to a slightly more
logical position.

This converts libmtd to the common xalloc helpers and in doing so, makes
memory allocation failures fatal rather than returning an error to the
caller. I think this is acceptable behavior.

Source files for libmtd, crc32, and fec are scattered throughout the
tree. Move them to a central location so they can be built into a
common "libmtd.a" library used by all mtd-utils programs.
This patch only renames/deletes files and does not change the content.
Also modify the build system and source code so that libmtd.a can be built
from a "common" location (lib/). Statically link all utilities at the top
level with libmtd.a . Minor changes to mkfs.ubifs to allow using the common
crc32 implementation.
