[PATCH] Return SIM file access conditions from read_file_info.

[Denis Kenzior]

Hi,

I've pushed this patch with some modifications afterward.  From reading the 
spec myself, I noticed that our interpretations are a 'bit' different.

According to TS 11.11 9.3:
- Read is in byte 9, upper 4 bits
- Update is in byte 9, lower 4 bits
- Increate is in byte 10, upper 4 bits
- Rehabilitate is in byte 11, upper 4 bits
- Invalidate is in byte 11, lower 4 bits

I've reworked the code according to the above spec.

Yet in your implementation they were in bytes 10-12 with lower & upper 
swapped.  E.g. Read in byte 10, lower 4 bits.

Can you confirm that my interpretation is correct, or am I missing something?

Regards,
-Denis
