SoC: remove already completed microprojects

Remove the microprojects that were completed and merged, and thus can't be re-used. Below the list of microprojects that were merged and removed from this list with the corresponding commit hashes: * Make "git -C '' cmd" not to barf: 6a536e2 * Make "git diff --no-index $directory $file" DWIM better: 0615173 + c9e1f2c * Forbid "log --graph --no-walk": 695985 And below a list of microprojects that are still in the list with some comments. * Allow "-" as a short-hand for "@{-1}" in more places: has been attempted multiple times (see $gmane/265260, $gmane/265240, $gmane/265562) but I couldn't find any commit that merged such functionality. * Use unsigned integral type for collection of bits: Couldn't find any attempt on the list or in the git log. * Move ~/.git-credentials and ~/.git-credentials-cache to ~/.config/git: git-credentials was moved in 558e5a8, as part of a larger cleanup series. Reword the project so only ~/.git-credentials-cache is left. * Add configuration options for some commonly used command-line options: This was completed outside the scope of a GSoC microproject in e97a5e7. But there are other commands that could probably benefit, so it's left in. The description should still be changed. * Add more builtin patterns for userdiff: This had no takers, so it's left in.
