[PATCH 0/5] slimming down installed size

[Jeff King <peff@peff.net>]

A while ago I was looking at the size of an installed (and stripped)
build of Git, and noticed we could make a few more things into builtins.

Patches 2-4 do that.  I don't think there's any real downside here.
We're not bringing in any new link dependencies to the main binary. And
even if these programs don't use all of the code that's in the main
binary, operating systems are good at just loading the pages that we do
need (and you're probably running other Git programs anyway, which means
the main binary is in RAM anyway and we're actually reducing the overall
memory footprint).

The final patch is not strictly related, but it's something I've had
sitting around for a long time. I actually posted it almost exactly two
years ago:

  https://lore.kernel.org/git/20180817190310.GA5360@sigill.intra.peff.net/

which ended with Jonathan saying:

So...I held off for a bit, but I'd really like to be done with this (and
I prefer dropping the code, because I have a few other tree-wide
cleanups for which I'd just as soon not have to deal with vcs-svn).

  [1/5]: Makefile: drop builtins from MSVC pdb list
  [2/5]: make credential helpers builtins
  [3/5]: make git-bugreport a builtin
  [4/5]: make git-fast-import a builtin
  [5/5]: drop vcs-svn experiment
