Most of the API calls that default an arg to ALL_CHANS or ALL_MBOARDS
were in fact broken. This adds a macro to efficiently mux out API calls
that take such wildcard arguments so we don't have to repeat the same
loop all over the place, even for those API calls that already correctly
implemented wildcards (for consistency).

For RFNoC devices, multi_usrp::get_device() no longer returns a device
pointer, rather, it returns a nullptr.
This is intentional because access to the underlying device is no longer
allowed. However, legacy code can segfault (e.g. portions ofr gr-uhd).
This patch returns a faux uhd::device class, which almost mimicks the
original behaviour perfectly, by redirecting its class methods back to
multi_usrp_rfnoc. The only exception is recv_async_msg(), which requires
a TX streamer. This function will always return false now.

This allows access to the underlying property tree without having to
refer to the device object. Useful for RFNoC objects, where the device
object is not accessible.

This adds a new API call to multi_usrp: get_gpio_src_banks(). This
returns a list of GPIO banks who's source can be controlled through the
motherboard controller.
The remaining GPIO source methods' docstrings are improved, to explain
the difference between GPIO banks for set_gpio_attr() and
set_gpio_src(). The former controls the actual value on a GPIO bank, and
the latter who drives it. These can be different banks.

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.

When calling a multi_usrp object like this:
usrp->set_gpio_attr("TXB", "CTRL", 0xFFFF);
Previously, it would only be able to address daughterboard A. Now, there
is a full backward-compatible solution (compatible with 3.15), that will
address either daughterboard's GPIOs.

This API call is a more explicit way of setting the spp than passing in
an spp value in the args of the stream args when creating streamers. For
pre-RFNoC devices, this is done by injecting the spp arg back into the
stream args. For RFNoC devices, the set_property() call on the radio is
called.

This removes the following Boost constructs:
- boost::shared_ptr, boost::weak_ptr
- boost::enable_shared_from_this
- boost::static_pointer_cast, boost::dynamic_pointer_cast
The appropriate includes were also removed. All C++11 versions of these
require #include <memory>.
Note that the stdlib and Boost versions have the exact same syntax, they
only differ in the namespace (boost vs. std). The modifications were all
done using sed, with the exception of boost::scoped_ptr, which was
replaced by std::unique_ptr.
References to boost::smart_ptr were also removed.
boost::intrusive_ptr is not removed in this commit, since it does not
have a 1:1 mapping to a C++11 construct.

This adds a separate version of multi_usrp for RFNoC devices. It is
compatible with RFNoC devices only, and prefers C++ APIs over property
tree usage. The factory of multi_usrp is modified such that it picks the
correct version, users of multi_usrp don't care about this change.
This also introduces some API changes:
- Removing redundant GPIO functions. Now all GPIO control, setting, and
readback is done with uint32_t's.
- Adding getter/setter for GPIO source. This was done to simplify the
other GPIO settings, as the source for each pin is not always a
binary. The CTRL mode, for example, can either be ATR or GPIO.
However, the source can be controlled by various radios or "PS" or
some other source.
- Removing the mask from the RFNoC radio controllers' set_gpio_attr().
- Adding state caching to gpio_atr_3000, and a getter for it. Whenever
an attribute is set, that value is cached, and can now be retreieved.
- Remove low-level register API. Since UHD 3.10, there is no USRP that
implements that API.
Modifying the filter API in the following ways:
- Splitting filter API getter/setter/list into separate RX and TX
functions
- Adding channel numbers as an argument
- The filter name will no longer be a property tree path, but rather a
filter name. For RFNoC devices, this will take the form
`BLOCK_ID:FILTER_NAME`. For non-RFNoC devices, this will just be the
filter name (e.g. `HB_1`)
- Removing search mask from listing function. Users can do their own
searching
