Merge branch 'ps/build-sign-compare'

Start working to make the codebase buildable with -Wsign-compare.

* ps/build-sign-compare:
  t/helper: don't depend on implicit wraparound
  scalar: address -Wsign-compare warnings
  builtin/patch-id: fix type of `get_one_patchid()`
  builtin/blame: fix type of `length` variable when emitting object ID
  gpg-interface: address -Wsign-comparison warnings
  daemon: fix type of `max_connections`
  daemon: fix loops that have mismatching integer types
  global: trivial conversions to fix `-Wsign-compare` warnings
  pkt-line: fix -Wsign-compare warning on 32 bit platform
  csum-file: fix -Wsign-compare warning on 32-bit platform
  diff.h: fix index used to loop through unsigned integer
  config.mak.dev: drop `-Wno-sign-compare`
  global: mark code units that generate warnings with `-Wsign-compare`
  compat/win32: fix -Wsign-compare warning in "wWinMain()"
  compat/regex: explicitly ignore "-Wsign-compare" warnings
  git-compat-util: introduce macros to disable "-Wsign-compare" warnings
