Up until now, we completely ignore the XDG specification.
This commit does the following to change that:
- It uses XDG_DATA_HOME and XDG_CONFIG_HOME for cal and config data,
respectively.
- If config data is in ~/.uhd/uhd.conf, that is still accepted, but if
it conflicts with $XDG_CONFIG_HOME/uhd.conf, it is ignored and a
warning is displayed
- The default location for cal data is thus ${HOME}/.local/share/uhd/cal
on Unix, and %LOCALAPPDATA%\uhd\cal on Windows. This is a change in
location!
- The UHD_CONFIG_DIR environment variable was confusingly named and is
now removed. It provided an alternative location than the home
directory. The same purpose is now much better served by XDG_DATA_HOME
and XDG_CONFIG_HOME.
The specification can be found here:

Note: template_lvbitx.{cpp,hpp} need to be excluded from the list of
files that clang-format gets applied against.

The prefs API is supposed to load the config files once, and stash them
away for the process to consume at will. Because the init_done is never
set, it will read the config files every time it's asked for them. This
is usually not a problem, but it causes the logging output to be messy.

Swap out hyphens for underscores in the DPDK args. Also update list
of distributions with the correct DPDK version in the repos.

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.

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
