4c7e4b7738
All files that were including one of the following include files have been updated to only include haproxy/api.h or haproxy/api-t.h once instead: - common/config.h - common/compat.h - common/compiler.h - common/defaults.h - common/initcall.h - common/tools.h The choice is simple: if the file only requires type definitions, it includes api-t.h, otherwise it includes the full api.h. In addition, in these files, explicit includes for inttypes.h and limits.h were dropped since these are now covered by api.h and api-t.h. No other change was performed, given that this patch is large and affects 201 files. At least one (tools.h) was already freestanding and didn't get the new one added.
