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:
- CURLGSSAPI_DELEGATION_FLAG
- CURLGSSAPI_DELEGATION_NONE
- CURLGSSAPI_DELEGATION_POLICY_FLAG
- CURLMIMEOPT_FORMESCAPE
- CURLSSH_AUTH_AGENT
- CURLSSH_AUTH_ANY
- CURLSSH_AUTH_DEFAULT
- CURLSSH_AUTH_GSSAPI
- CURLSSH_AUTH_HOST
- CURLSSH_AUTH_KEYBOARD
- CURLSSH_AUTH_NONE
- CURLSSH_AUTH_PASSWORD
- CURLSSH_AUTH_PUBLICKEY
Also:
- keep existing cast within the documentation to make sure it applies
to older curl versions as well.
Closes#18134

- the year range is kept in COPYING
checksrc is updated to allow non-year using copyright statements
Closes#10205
Add licensing and copyright information for all files in this repository. This
either happens in the file itself as a comment header or in the file
`.reuse/dep5`.
This commit also adds a Github workflow to check pull requests and adapts
copyright.pl to the changes.
