[PATCH v7 0/7] strbuf cleanups

[Calvin Wan <calvinwan@google.com>]

I rebased this series onto 2.41 and noticed I was getting a compilation
error for a missing dependency to repository in dir.h. With all of the
other cleanups happening, I assume some dependency chain that used to
exist doesn't anymore. This reroll moves "strbuf: clarify dependency" to
the second patch so any dependency chain broken by the other cleanup
patches can be caught. And that is why patch 4 adds a forward
declaration back. I also caught an additional unnecessary dependency
that could be removed in patch 5. This series should now be able to be
rebased onto 2.41 without any issue.

Calvin Wan (7):
  strbuf: clarify API boundary
  strbuf: clarify dependency
  abspath: move related functions to abspath
  credential-store: move related functions to credential-store file
  object-name: move related functions to object-name
  path: move related function to path
  strbuf: remove global variable
