[RFC PATCH v2 0/4] developer: support pedantic

WARNING: this will break CI with seen when merged and unless the
kwown pedantic issue still remaining from fsmonitor[0] is merged
first (expected to come in a reroll)

this series has a different subject than v1 and that is currently tracked as cb/ci-build-pedantic, but is a reroll (even if it discards all changes from v1) and was originally suggested by Phillip as an alternative.

because of that, it might conflict with changes proposed by Ævar[2] but that are still not in "seen" AFAIK and merges cleanly otherwise.

first patch was suggested[1] by Peff, so hopefully my commit message and his assumed SoB are still worth not mixing it with patch 2 (which has a slight different but related focus and touches the same files) but since it is no longer a single patch, lets go wild.

patches 3 and 4 are optional and mostly for RFC, so that a solution to any possible issue that the retiring of USE_PARENS_AROUND_GETTEXT_N are addressed.

Carlo Marcelo Arenas Belón (3):
  developer: enable pedantic by default
  developer: add an alternative script for detecting broken N_()
  developer: move detect-compiler out of the main directory

Jeff King (1):
  developer: retire USE_PARENS_AROUND_GETTEXT_N support
