This is primarily a minor refactor with the exception
of non-recoverable errors - notably if the receive times
out - which almost always requires a reload of the FPGA.
In these cases, quit without trying as resistance is
futile.
ERROR_TIMING: Soft restart of streaming
ERROR_UNHANDLED: Benign errors
ERROR_UNRECOVERABLE: Abandon ship
Non-recoverable behaviour has not been observed in recent
builds, but may exist in older (or future) configurations.

Overnight testing shows that this shouldn't be required
in the majority of cases, but shit happens. Enabling
this forces transmit timing realignment at one minute
intervals. As a fallback method, timing slips not
caught by normal checks will be reset at the update.

At startup, instead of flushing initial packets blindly,
send a stop streaming command, flush, and start. The same
procedure is used in the event of a runtime timestamp
validity error.

The output of the modulator or resampler is scaled and
converted from floating point to fixed point. The scaling
factor is the leftover dB in RF attention (relative to max
transmit power), which is handled prior to the integer
conversion. This should work across all daughterboards and
non-UHD installations.

Previously this was referenced off the the ad9862
PGA with a range from 0 to -20 dB. Instead base
the attenuation factor on the maximum total RF
gain returned by the device.

On a lapses of time monotonicity (and possibly other errors),
stop and restart the receive streaming with a buffer flush
in between. This is a cleaner replacement to the previous
clock reset with that didn't attempt to stop steaming.

Type size_t was used in the UHD time_spec_t to integer
conversion, which would overflow at roughly 4 and a half
hours causing the sample buffer to error on timestamp
validity. Builds where size_t takes on 64-bits were not
affected by this bug.

With UHD b4fc0d61bb6cbd1a5614745bab9aeb0abc22cb6f
Sample clock will reset to zero after an overrun. Earlier
versions may hang the FPGA, which is non-recoverable,
requiring a manual image reload or reboot.
If reset to zero, attempt to kick the sample clock to the
last properly received timestamp value. At this point,
there will be a timing continuity jump, which will drop
connections, but transmit and receive chains should be
aligned allowing for re-establishment.

Occasionally, the E100 will have errant timestamps at start
related to previous sessions. Early packets will be thrown
out anyways, so do this explicitly so the timestamps don't
royally fuck up the sample timing.

Remove all RFX specific parts and control daughterboard
functionality using the base API. The tuning is now set
to a non-inverted image so remove the I/Q swap as well.
Daughterboard configuration is set through an enum
variable. Currently, there is no auto-configuration and
the default is Tx/RX on sides A/B respectively. For
transceiver boards the receive antenna is set to RX2.
enum dboardConfigType {
TXA_RXB,
TXB_RXA,
TXA_RXA,
TXB_RXB
};
const dboardConfigType dboardConfig = TXA_RXB;
