[L] Change in libosmocore[master]: core: Add software UART implementation

Attention is currently required from: fixeria, laforge. fixeria has uploaded a new patch set (#3) to the change originally created by laforge. ( https://gerrit.osmocom.org/c/libosmocore/+/30763?usp=email ) The following approvals got outdated and were removed: Verified-1 by Jenkins Builder Change subject: core: Add software UART implementation ...................................................................... core: Add software UART implementation This patch brings a Work-in-Progress implementation of the software UART (Universal Asynchronous Receiver/Transmitter) to libosmocore. Not only it will be useful in the context of retro-networking, but also it's needed for the MS-side CSD implementation (see OS#4396). It should be noted that the definition of struct osmo_soft_uart is intentionally kept private, since the API is not stable yet. Currently, the following limitations apply: * Only the receiver part is implemented, the transmitter is TBD. * Parity checking is not implemented in the receiver part. * Software flow control is not implemented. These missing components will be addressed in subsequent patches.
