FAT volume LABEL property configuration

[oleszczyk]

Currently when running USB MSC with FAT file system disk on host side it is visible as "non label volume":

This form of volume presentation on host OS is especially confusing when there is MSC with multiple LUNs (like on the screenshot above).

It turns out that FAT FS implementation is supporting f_setlabel(...) function which could be used for volume label configuration. The question here is: how it should be handled from user app?

File System interface is limited to only those actions. So there are 2 options:

1. extend File System API to add something like .setlabel field,
2. insert f_setlabel(...) call inside one of already existing API functions (maybe fatfs_mount?).

Please give me a feedback what do you thinks about that.
