The 5G phone OPPO has a very big UE capability (> 2KB).

We need bigger buffers to transfer this, especially in x2 handover.

Also the sctp messages need a bigger buffer.

Note: in sctp, we didn't check for partial messages, it's now
      done. When detected, we exit. To be redone differently
      if needed. (Look for "if (!(flags & MSG_EOR))".)

We declare variables in header files, we don't define them. So we need
to use 'extern' in the header file and put the definition
in some C file.

This used to be done to ease power estimation in the UE,
but this is not correct. Let's put no energy in the REs
with no DCI data, which is what needs to be done.

Plus it consumes a lot of CPU because of calling taus()
way too much.

To be used when you send data to another host.

On the other host, to avoid ICMP traffic about the port
not being open, do:

./nc -l -u -p 9999 > /dev/null

You need to restart this command each time you run macpdu2wireshark.
You can use any other program that will accept UDP packets on the
port 9999 (default port of macpdu2wireshark, change if you use another
port of course).

Some computation has been fixed in PUCCH reception.

SNR has been fixed, uses measurement instead of
a fixed value for the noise.

normalized_rx_power and target_rx_power have been removed,
replaced by snr and target_snr. All the files using those
variables have been updated.
