Subject: build: drop duplicate C includes
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7d9004ee478878a494eb11776a53e9a58d08a8ef;p=thirdparty%2Fcurl.git

build: drop duplicate C includes

- `stdlib.h` and `string.h` is included via `curl_setup_once.h`,
  allowing to drop from `tests/server` sources and `tool_doswin.c`.

- `stdlib.h` is also included via `setup-vms.h` (earlier than above),
  allowing to drop it from `curl_addrinfo.h` on VMS.

Closes #20303
