Paul Tan 8c3bd9e288 builtin-am: implement patch queue mechanism ... git-am applies a series of patches. If the process terminates abnormally, we want to be able to resume applying the series of patches. This requires the session state to be saved in a persistent location. Implement the mechanism of a "patch queue", represented by 2 integers -- the index of the current patch we are applying and the index of the last patch, as well as its lifecycle through the following functions: * am_setup(), which will set up the state directory $GIT_DIR/rebase-apply. As such, even if the process exits abnormally, the last-known state will still persist. * am_load(), which is called if there is an am session in progress, to load the last known state from the state directory so we can resume applying patches. * am_run(), which will do the actual patch application. After applying a patch, it calls am_next() to increment the current patch index. The logic for applying and committing a patch is not implemented yet. * am_destroy(), which is finally called when we successfully applied all the patches in the queue, to clean up by removing the state directory and its contents.
