Subject: CURLOPT: bump `CURL_SSLVERSION_*` macros to `long`
X-Git-Tag: curl-8_16_0~286
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ebbb8e3da75ee57925560ae0d352edfde86def07;p=thirdparty%2Fcurl.git

CURLOPT: bump `CURL_SSLVERSION_*` 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:

- CURL_SSLVERSION_DEFAULT
- CURL_SSLVERSION_SSLv2
- CURL_SSLVERSION_SSLv3
- CURL_SSLVERSION_TLSv1
- CURL_SSLVERSION_TLSv1_0
- CURL_SSLVERSION_TLSv1_1
- CURL_SSLVERSION_TLSv1_2
- CURL_SSLVERSION_TLSv1_3

- CURL_SSLVERSION_MAX_DEFAULT
- CURL_SSLVERSION_MAX_NONE
- CURL_SSLVERSION_MAX_TLSv1_0
- CURL_SSLVERSION_MAX_TLSv1_1
- CURL_SSLVERSION_MAX_TLSv1_2
- CURL_SSLVERSION_MAX_TLSv1_3

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

Closes #18135
