Bug fixes of srseNB scheduler TPC
...
- fix encoding of TPC command
- use of exponential average with irregular sampling for the ULSNR average estimate.

when a TPC is encoded

enb_mac: pre-allocate UE object for quicker PRACH/RAR handling
...
we've seen long delays in handling PRACH on low-power devices
such as the RPi4. This was mainly caused by long delays
in creating the UE object on the fly during PRACH handling.
This patch pre-allocates one UE object that is then used
during the PRACH.

extend eNB MAC to support multiple CC per UE
...
- add tx/rx softbuffers for each CC that a UE might have
- make sure to call assign correct buffers when iterating
over the CC for UL/DL grant assignment

fix SIB transmission for CA
...
Avoid double buffering of SIBs in MAC as this would require one buffer for each CC.
Instead, use byte_buffer managed by RRC that contains packed SIBs to avoid
double memcpy for each SIB tx. Only use MAC provided buffer in error case.
Also avoid MAC calling RLC for each SIB and call RRC directly.

refactor cell param handling and fix SIB transmissions
...
- move cell specific eNB params to cell list in rr.conf
- make sure DL EARFCN and DL freq can be used to manually overwrite a single cell config
- fix SIB packing and transmission for multi cell configs
- introduce cell list to MAC
- adapt default enb.conf.example and rr.conf.example
