commit c13f8bde8f "merged in commercial
openbts" removed AC_CONFIG_MACRO_DIR in configure.ac, which in effect
disabled SSE support on environments where the detection macro, AX_EXT,
was not already present.
Rather than rely on AX_EXT be present in the distribution, use the
version that is already included with OpenBTS by re-enabling the config
m4 directory.

An errant shuffle register value used in complex-complex convolution
causes distorted correlation peak-to-average values for certain TSC
values. The error effect varies for different TSC sequences with the
most noticeable effect of degraded detection on TSC 1 and no effect on
TSC 7.

Fixed all places where + was not being sent. Plus can't be sent as a digit it has to be encoded as an international type.
Fixed error where # is displayed in reply address for +.
SMS reply not working with plus in from address.
Fixed all places in smqueue that crash on purpose when bad data is found.
Fixed several other crashes related to handling missing tags.
Added support for receiving addresses with and without +. Whether a + is received or not depends on what the sender enters.
3gpp mode is working.
Fixed error where smqueue gets into an infinite loop when restarted with bad messages in the queue.
Patch e5aa3f9975 "Set B2XX clock frequency
to 26 MHz" was inadvertently reverted by
c13f8bde8f "merged in commercial openbts".

Underruns are only explicitly set on the downlink side. Overruns
are logged but unused. In either case, reset indicators to false
to avoid sending false state information.

Use the same measurement method for RSSI as the noise level. Previous
method was to use the peak correlation amplitude relative to the
expected value. This created two very different amplitude approaches
between the noise measurement and RSSI measurement, which would
throw off the upper layer MS power control loop.

Previous removal of the energy detector requirement broke
the noise level calculation loop. The previous adaptive
approach was finicky - noticably at high gain levels. Since
we no longer use the energy threshold for primary burst gating,
we can return to a simpler world.
In the new approach, we compute a running average of energy
levels and track them with a noise vector. A timeslot that
passes the correlator threshold is a valid burst. These are
not used in the noise calculation. Everything else is
considered noise and used to compute the noise level with
respect to full scale input level, which for almost all
supported devices is 2^15.
