[WIP PATCH 0/4] Support for UDF 1.01 and 2.60 revisions

[Pali RohÃr]

These are my work-in-progress patches for UDF 1.01 and 2.60 revisions.
Patches are untested and UDF 2.60 support is only in R/O mode.

I'm sending them to know what do you think about it. There is missing
code for parsing of numFiles, numDirs, minUDFReadRev and minUDFWriteRev
values from UDF 1.50 VAT discs, but this could be done in other patches.

PS: If somebody is interested in UDF 1.01 specification, please let me
know and I could send it. It is missing on OSTA website.

Pali RohÃr (4):
  udf: Do not access LVIDIU revision members when they are not filled
  udf: Fix reading numFiles and numDirs from UDF 2.00+ VAT discs
  udf: Fix reading minUDFReadRev and minUDFWriteRev from UDF 2.00+ VAT
    discs
  udf: Allow to read UDF 2.60 discs
