Adapt io.c in libubifs, compared with linux kernel implementations:
1. Modify io related functions(eg. ubifs_leb_read/ubifs_leb_write,
etc.), adapt them with userspace io functions lseek/read/write.
2. Remove some functions(eg. record_magic_error, ubifs_bg_wbufs_sync)
which won't be used in fsck/mkfs.
3. Replce ubifs_errc with ubifs_err, because there will be no SB_SILENT
options in mkfs/fsck.
4. Initiate wbuf->size as c->max_write_size.

Because of namespace collisions mkfs.ubifs uses crc32() implementation from
/lib/libz.so.1, which generates incompatible CRC and later on the kernel reports
many CRC errors.
Fix this by re-naming mtd-utils' crc32 function to mtd_crc32.

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.
