trans.c : reworking of transaction interruptions
My two previous hacks related to this part (8038190c7c4786e1c49494eea1b40cdddcbd5136 and b15a5194d1a8485a2769560e49e6ff03e1862533) were caused by the lack of understanding of a feature introduced a while ago: Better control over CTRL-C interruptions -- do not leave the DB in an inconsistent state (54008798efcc9646f622f6b052ecd83281d57cda). Now I have been looking at this commit, and the added feature is indeed interesting. The main problem I had with it is that it does a rather unusual use of alpm_trans_release, which caused a few problems that I tried to fix in a weird way. I think these problems were caused by the fact that there weren't any difference between "interrupt transaction" and "release a transaction which failed" actions from the alpm_trans_release POV. So I decided to add a new function instead, alpm_trans_interrupt, which is called on Ctrl+C, and which only sets trans->state to STATE_INTERRUPTED so that remove_commit and add_commit can exit cleanly at a safe moment. This allowed me to revert my two previous hacks as well. Also ensure we handle SIGINT correctly in all cases- if a transaction is not ongoing, then we can free the transaction and exit quickly.
