Subject: CURLOPT: bump `CURLALTSVC_*` macros to `long`
X-Git-Tag: curl-8_16_0~349
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d45b85d79198a0259123923a6aa186ded2aaca6c;p=thirdparty%2Fcurl.git

CURLOPT: bump `CURLALTSVC_*` macros to `long`

This patch bumps the size of these macros from `int` to `long`, while
keeping their actual values the same. It may cause incompatibilities in
user code, requiring the bump of holder variables and/or adding casts:

- CURLALTSVC_H1
- CURLALTSVC_H2
- CURLALTSVC_H3
- CURLALTSVC_READONLYFILE

Also:
- keep existing cast within the documentation to make sure it applies
  to older curl versions as well.

Closes #18063
