Change in osmocom-bb[master]: trxcon: allow populating global SACCH cache via L1CTL

Attention is currently required from: pespin. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmocom-bb/+/28874 to look at the new patch set (#3). Change subject: trxcon: allow populating global SACCH cache via L1CTL ...................................................................... trxcon: allow populating global SACCH cache via L1CTL There is a time window between activation of a dedicated channel and receipt of a L1CTL_DATA_REQ with the first RR Measurement Report, in which trxcon may need to start transmission on Uplink SACCH. In this case trxcon is using a dummy SACCH block with hard-coded L1 SACCH header values and hard-coded Measurement Results. This mimics behavior of the layer1 implementation in firmware for Calypso phones. When running the mobile application, this error can be seen: DAPP ERROR trxcon(0)[0x55ee57bee1a0]{FBSB_SEARCH}: Event TRXCON_EV_RX_DATA_IND not permitted which means that the mobile is sending L1CTL_DATA_REQ *before* establishing a dedicated channel. And this message contains an RR Measurement Report. The idea behind this is to populate the SACCH cache in advance and thus avoid sending dummy values. Let's allow the L2 apps populating SACCH cache before establishing a dedicated connection using new TRXCON_EV_UPDATE_SACCH_CACHE_REQ.
