[PATCH 0/2] split libosmocore library (to create libosmo-gsm)

Hi! The following patches split libosmocore in two libraries, the new libosmo-gsm, which contains GSM-specific functions, and libosmocore, which contains generic functions (like talloc, msgb, select, logging, ...). In case that you're OK with them, you have to apply them in the following way: 1) First, make a copy of libosmocore.git to libosmo-gsm.git. This is done to avoid losing the history in the new libosmo-gsm.git library. $ cp -r libosmocore.git libosmo-gsm.git 2) Apply the patch that removes the GSM-specific features to libosmocore.git (see [PATCH 1/2]) 2) Apply the patch that removes the non-GSM features to libosmo-gsm.git (see [PATCH 2/2]) After these patches, I'll send two patches for openbsc and osmocore-bb to make them use the new libosmo-gsm. Let me know what you think with this proposal.
