The failure "UHD make failed" implies that a suitable device
was found, but construction failed. Output the the found
target device information along with message.

Unrecoverable device errors include send and receive
timeouts and mangled packets. Other device errors, such
as non-monotonic timestamps are sometimes recoverable
through a soft restart.
These fatal are generally limited to development
versions of UHD driver or device firmware, but can occur
in release versions.
Alert user on such device errors along with current UHD
version.

Changed the RRLP test scripts to provide instructions on their use.
Changed the RRLP test scripts and OpenBTS default SQL to use Sather Tower as the default location for RRLP traffic.
Remove the sendrrlp command from the OpenBTS CLI

Device errors regarding properties such as sample
rate or frequency tuning are almost always fatal and
lead to the common error "assuming TRX is dead".
Make sure that these errors are clearly presented to
the user.

Perform a UHD device search before constructing the object,
and inform the user if no device is found.
No device found is the most common reason for the transceiver
to fail with the dreaded error "assuming TRX is dead".

This configuration is invalid because of FPGA based timestamp
support for the USRP1 in the UHD driver.
Kindly inform the user to recompile with libusrp support from
GNU Radio.

Before setting the master clock rate, make sure that the
device is capable of being set. For now, assume that devices
that operate with default clock rates above 64 MHz,
specifically USRP2/N200/N210, cannot be set at 52 MHz.
Inform the user that these devices can be used with the
compile time option of host based resampling.

It was possible to reach a state where a resampled burst would
overrun the transmit output buffer and corrupt the global
allocated signal vectors. The result was a segmentation fault
when attempting to access heap allocated signal vectors since
the pointers were garbage.
Whether the segfault occured or not appears to depend on the
memory location of the signal vector pointers, since it does
not occur on all systems.
Double buffer size to accomodate an incoming burst plus up to
a full chunk that may be remaining from the previous resampling
operation.

Not sure why this functionality is commented out.
Make install places the FPGA firmware image in:
/usr/local/share/usrp/rev2/

With transceiver integration, the resampling filter files were
dropped. This created a working resampling implementation for
the USRP2 / N200, but with spectrum irregulaties that likely
caused issues at longer range operation. Simply reinsert the
filter files and modify the filter initialization to use them.
