Higher ICB limit than Windows

[HT-7]

It appears that the bogus UDF 2.60 driver on Windows can not write ICBs (information control blocks) beyond block 25376 (source). This means that once block 25376 of the metadata track is reached, the rest of the main data track (where the files reside) becomes read-only.

Please make sure the Linux UDF driver does not have this bug, and also make fsck.udf able to remove the 25376 bug to make read-only Blu-ray discs with free remaining space writable again. (The 25376 bug can be reproduced by writing a high number of small files to BD-R using Windows File Explorer.).
