btrfs-progs: balance: enhance the limit fiter with range 

We can do more with the balance filter. Enhance it so we can specify
also the minimum number of block groups to process. The 'limit' filter
now accepts a range (a..b, can be partial) and needs kernel support.

The 'limit=value' filter is equivalent to 'limit=..value' but works on
older kernels as well.

The min/max values are 32bit, unlike the single-value limit which is
64bit.
