JIRA: RTOS-927

Description

Motivation and Context

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Chore (refactoring, style fixes, git/CI config, submodule management, no code logic changes)

How Has This Been Tested?

• Already covered by automatic testing.
• New test added: (add PR link here).
• Tested by hand on: (list targets here).

• My change requires a change to the documentation.
• I have updated the documentation accordingly.
• I have added tests to cover my changes.
• All new and existing linter checks and tests passed.
• My changes generate no new compilation warnings for any of the targets.

Special treatment

• This PR needs additional PRs to work (list the PRs, preferably in merge-order).

I would rather fix these issues in ports by local patches than disable warnings.

lighttpd is slightly bugger issue, because we have an upgrade PR to 1.4.77 pending, so patching lighttpd before PR is merged may be wasteful

mbedtls (2.28.0) does the following:

#if defined(__socklen_t_defined) || defined(_SOCKLEN_T) ||  \
    defined(_SOCKLEN_T_DECLARED) || defined(__DEFINED_socklen_t) || \
    defined(socklen_t) || (defined(_POSIX_VERSION) && _POSIX_VERSION >= 200112L)
    socklen_t n = (socklen_t) sizeof( client_addr );
    socklen_t type_len = (socklen_t) sizeof( type );
#else
    int n = (int) sizeof( client_addr );
    int type_len = (int) sizeof( type );
#endif

Apparently, we don't define any such macros, commonly found in glibc, musl, FreeBSD's libc, etc. (We only define SOCKLEN_T_DEFINED in lwip.) We don't even have _POSIX_VERSION defined in unistd.h. I think defining _POSIX_VERSION is the way to go.

Finally, we opted for _SOCKLEN_T phoenix-rtos/libphoenix#408 Defines which shadow existing types cause LSP/IDEs to only show macro expansion instead of treating it as a type

This changes do not disable warnings but rather mark warnings as not errors. There are more warnings in the ports. I do not think that patching all of them is feasible.

phoenix-rtos/libphoenix#408 is merged now so you can omit the mbedtls patch
