Subject: vquic: use new curl_int64_t type
X-Git-Tag: curl-8_8_0~287
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9287563e86a5b2007fb67f68c075a87a93825861;p=thirdparty%2Fcurl.git

vquic: use new curl_int64_t type

- add curl_int64_t signed 64-bit type for lib use

- define CURL_PRId64, CURL_PRIu64 format ids

- use curl_int64_t in vquic

curl_int64_t signed complements the existing curl_uint64_t unsigned.

Note that `curl_int64_t` and `int64_t` are assignable from each other
but not identical. Some platforms with 64 long type defint int64_t as
"long long" (staring at macOS) which messes up things like pointers and
format identifiers.

Closes https://github.com/curl/curl/pull/13293
