f845fced91 udf: use crc_itu_t from lib instead of udf_crc
As pointed out by Sergey Vlasov, UDF implements its own version of
the CRC ITU-T V.41.  Convert it to use the one in the library.

bfb257a598 udf: Add read-only support for 2.50 UDF media
This patch implements parsing of metadata partitions and reading of Metadata
File thus allowing to read UDF 2.50 media. Error resilience is implemented
through accessing the Metadata Mirror File in case the data the Metadata File
cannot be read. The patch is based on the original patch by Sebastian Manciulea
<manciuleas@yahoo.com> and Mircea Fedoreanu <mirceaf_spl@yahoo.com>.

f4bcbbd92e udf: Fix handling of multisession media
According to OSTA UDF specification, only anchor blocks and primary volume
descriptors are placed on media relative to the last session. All other block
numbers are absolute (in the partition or the whole media). This seems to be
confirmed by multisession media created by other systems.

423cf6dc04 udf: Cleanup anchor block detection.
UDF anchor block detection is complicated by several things - there are several
places where the anchor point can be, some of them relative to the last
recorded block which some devices report wrongly. Moreover some devices on some
media seem to have 7 spare blocks sectors for every 32 blocks (at least as far
as I understand the old code) so we have to count also with that possibility.

This patch splits anchor block detection into several functions so that it is
clearer what we actually try to do. We fix several bugs of the type "for such
and such media, we fail to check block blah" as a result of the cleanup.

d0db181c07 udf: fix anchor point detection
According to ECMA 167 rev.  3 (see 3/8.4.2.1), Anchor Volume Descriptor
Pointer should be recorded at two or more anchor points located at sectors
256, N, N - 256, where N - is a largest logical sector number at volume
space.

So we should always try to detect N on UDF volume before trying to find
Anchor Volume Descriptor (i.e.  calling to udf_find_anchor()).

That said, all this patch does is updates the s_last_block even if the
udf_vrs() returns positive value.

Originally written and tested by Yuri Per, ported on latest mainline by me.

- size >= UDF_NAME_LEN:
    we copied UDF_NAME_LEN - 1 bytes, but dest->u_name is array

udf_get_filelongad and udf_get_shortad are called always for uint32_t
values (struct extent_position->offset), so it's safe to convert offset
parameter to uint32_t

gcc warned:
fs/udf/inode.c: In function 'udf_get_block':
fs/udf/inode.c:299: warning: 'phys' may be used uninitialized in this function
initialize it to 0 (if someday someone will break inode_getblk we will catch it immediately)

934c5e6019 udf: remove wrong prototype of udf_readdir
sparse generated:
fs/udf/dir.c:78:5: warning: symbol 'udf_readdir' was not declared. Should it be static?
there are 2 different prototypes of udf_readdir - remove them and move
code around to make it still compile
