We have multiple scripts that generate headers from other data. All of these scripts have the assumption built-in that they are executed in the current source directory, which makes them a bit unwieldy to use during out-of-tree builds. Refactor them to instead take the source directory as well as the output file as arguments. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
