Viktor Szakats 2f3fa479dd build: enable -Wformat-signedness, fix issues found ... Adjust code to avoid `-Wformat-signedness` warnings, while making sure that enums are always cast to a known type when passing them to `printf` functions, to support compilers and compiler settings where enums are not default-size signed ints. - cast integers printed as hex to `unsigned`. (63 times, 20 of them in `mbedtls.c`) - cast misc enums to `int` for printing. (31 times) - cast `CURL_LOCK_DATA_*` enums to `int`. (4 times) - cast `CURL_FORMADD_*` enums to `int`. (13 times) - cast `CURLSHE_*` enums to `int`. (3 times) - cast `CURLUE_*` enums to `int`. (33 times) - cast `CURLMSG_*` enums to `int`. (6 times) - cast `CURLE_*` enums to `int`. (~380 times) - unit1675: fix mask. Follow-up to 7c34365cce #21879 Ref: #18343 (initial attempt) Closes #20848		2026-06-10 15:14:08 +02:00
