With this patch, the elements of of the return value of find_blocks()
are sorted lexicographically (specifically, using
uhd::rfnoc::block_id_it::operator<()).
The underlying block_container class stores the blocks in an unordered
set, so the return value for find_blocks() was always sorted randomly.
multi_usrp_rfnoc had to sort the return values every time find_blocks()
was used to get a useful return value.
Because find_blocks() had no contract for the order of returned blocks,
this change simply sorts the return value before returning it.
multi_usrp_rfnoc is modified to remove all the sorts that are now
superfluous.
A good way to see the change is to run uhd_usrp_probe, which will now
contain content like this:
| _____________________________________________________
| /
| | RFNoC blocks on this device:
| |
| | * 0/DDC#0
| | * 0/DDC#1
| | * 0/DUC#0
| | * 0/DUC#1
| | * 0/DmaFIFO#0
| | * 0/Radio#0
| | * 0/Radio#1
Assuming the blocks don't change, the order of this list will always be
the same following this patch. Note that the order is unrelated to the
order on the control crossbar, which it never was.
