Benchmarks show that using C++ chrono features beats
uhd::get_system_time(), and the latter is simply not appropriate unless
a uhd::time_spec_t is required.

This is a portable version of POSIX's isatty(). Windows has its own
version, called _isatty(). UHD thus gains its own, portable version.
The underscores aren't beautiful, but they're necessary so we can
distinguish the POSIX version from the UHD version.

Add configuration sections to the UHD config file for NIC entries. Keys
are based on MAC addresses, and the entries beneath the section describe
which CPU and I/O thread to use for the NIC and its IPv4 address.
Make ring sizes configurable for uhd-dpdk. Ring size is now an argument
for packet buffers. Note that the maximum number of available buffers
is still determined at init!
Add ability to receive broadcasts to uhd-dpdk. This is controllable by
a boolean in the sockarg during socket creation. dpdk_zero_copy will
filter broadcast packets out.
Add dpdk_simple transport (to mirror udp_simple). This transport allows
receiving from broadcast addresses, but it only permits one outstanding
buffer at a time.
Fix IP checksum handling in UHD-DPDK.
TX checksums were not being calculated in the NIC, and in RX, the check
for IP checksums allowed values of zero (reported as none). Now packets
with bad IP checksums will be dropped.

Using new rpc client new API that ensure atomic setting of timeout on
each rpc call.

The current implementation of the UHD RPC client has a timeout that is
being accessed non-atomically. Many calls follow the pattern:
1. set_timeout(value)
2. request_rpc()
3. set_timeout(default)
which is not atomic. Other concurrent calls on the same rpc client may
change the timeout value; leads to unexpected behavior
These new set of function will, instead, handle
setting and re-setting the timeout atomically in the RPC request.

To avoid the proliferation of additional include directories and
multiple ways of including project-local headers, we now default to
moving all headers that are used across UHD into the uhdlib/
subdirectory.
Some #include statements were also reordered as they were modified for
closer compliance with the coding guidelines.
Internal cpp source files should now include files like this:
#include <uhdlib/rfnoc/ctrl_iface.hpp>

This defines and reads configuration files that can be used to customize
UHD's behaviour. On Unix systems, they default to:
/etc/uhd/uhd.conf
$APPDATA/.uhd/uhd.conf
On Windows systems, it will look in:
%ProgramData%/uhd/uhd.conf
%AppData%/.uhd/uhd.conf

SPDX headers were also updated to latest version 3.0.
