Subject: [PATCH] rules.mk, projects-dir.mk: Add git-log targets

The git targets of the workspace Makefile cover push, diff, and status, but
not history: inspecting commits means running git log by hand in a project
directory, and no target shows the history of all projects of a tree at
once.

Add git-log targets at both levels; the target suffix is passed to git log
as-is, so make git-log-5 asks for the last five commits.

- git-log-% in projects-dir.mk runs pgit.sh log over every project of the
  tree, one section per project
- git-log-% in rules.mk runs git log -$* in the current project directory
- git-log-tree-% in rules.mk runs git-log-$* in $(PROJECTS_DIR), giving the
  whole-tree view from inside a project; it prints a notice if PROJECTS_DIR
  is missing
