The logging API changes in UHD-3.11, which causes build failure if
not properly handled.

* Explicitly check for sqlite3 at configure stage, remove old include
dir, fix header inclusion.
* Use configure results for linking instead of hardcoded linker option
for sqlite.
* Add dependency on -dev package for .deb

Previous patch switches to using system-wide sqlite3 so it's safe to
remove local copy now.

This reverts commit 93ca09ea61d044e5f8662b28bf084c808cac4f2c.
Ettus Research recommends the use of 3.9 series of UHD releases,
but requiring this version has lead to issues with broken OBS and
packaged binaries by Debian, Ubuntu, and other distributions.

Versions of UHD prior to 3.9.0 are no longer supported.
Rather then backport and ifdef UHD version specific API and
behavioral changes, set minimum support to the current LTS
release, which is 3.9.0.

Introduce polyphase channelizer (Rx) and synthesis (Tx) filterbanks,
which serve as the signal processing backend for multi-carrier GSM.
Fast Fourier Transform (FFT) is used internally. FFTW is added as
a new build dependency.

UHD handles built in tick and floating point timestamp conversion
since version 003.005.004. This removes the need for separate UHD
timespec to tick conversion.

Setup '--with-sse' option to check system capabilities by default, but
allow disabling by the user. Selective SSE build options can be
controlled by the user by defining specific HAVE_SSE options.

This will shutup automake and make it stop complaining about the
following subdirectory warnings.
"warning: source file 'common/fft.c' is in a
subdirectory, but option 'subdir-objects' is disabled"

Similar to the existing Intel SSE cases, add support for NEON vector
floating point SIMD processing. In this case, use ARM assembly
directly as the NEON intrinsics do not generate preferential code
output.
Currently support NEON vectorized convolution and floating point
integer conversions.

Currently the default configuration is to not build the full
transceiver, which is pointless. Set the UHD driver, which
includes either Ettus or Fairwaves variants, as the default.

Enabling the external reference on UHD devices through the configure
time switch is awkward. Use a database variable "TRX.Reference" with
'0' or '1' value for internal and external references respectively.
Use internal reference is no entry is defined.

Current functionality with these old versions is questionable.
There is no reason to use any version of GNU Radio / libusrp older
than 3.3. Version 3.4.2 is the only recommended version for USRP1
users.
Non-USRP1 users must use UHD driver from Ettus Research.

This large patch replaced the convolve() call with an SSE vector
enabled version. The lower C and SSE intrinsic based code operates
on fixed and aligned vectors for the filter taps. The storage format
of interleaved I/Q for both complex and real vectors is maintained.
SSE filter tap values must:
1. Start 16-byte aligned
2. Number with a multiple of 4 between 4 and 20 for real taps
3. Number with a multiple of 4 for complex taps
Non-compliant values will fall back to non-SSE usage. Fixed length
iterators mean that head and tail cases may require reallocation of
the input vector, which is automatically handled by the upper C++
interface.
Other calls are affected by these changes and adjusted or rewritten
accordingly. The underlying algorithms, however, are unchanged.
generateGSMPulse()
analyzeTrafficBurst()
detectRACHBurst()
Intel SSE configuration is automatically detected and configured at
build time with Autoconf macros.

Remove the built time resampling selection and link both options.
Move the normal push/pullBuffer() calls back to the base class and
overload them in the inherited resampling class.
USRP2/N2xx devices are the only devices that require resampling so
return that resampling is necessary on the device open(), which is
the point at which the device type will be known.
The GSM transceiver only operates at a whole number multiple of
the GSM rate and doesn't care about the actual device rate and
if resampling is used. Therefore GSM specific portion of the
transceiver should only need to submit the samples-per-symbol
value to the device interface.
Then, the device should be able to determine the appropriate
sample rate (400 ksps or 270.833 ksps) and if resampling is
appropriate.

This patch is long overdue and can now be merged after better understanding
of timestamp stability issues. UHD tick / timespec conversions were
generally used with the streamer interface, though these calls are actually
independent change sets. The combination would lead to internal rounding
errors and a timing drift most notably on B100 running at GSM symbol
rate multiples. There are no known issues, however, with the streamer code
itself.
The aforementioned issue was discovered in test code only, which was never
merged to mainline.
