Silence compiler warnings (200 of them across the main CI workflows):
```
warning #2193: null argument provided for parameter marked with attribute "nonnull"
warning: Null pointer passed to 1st parameter expecting 'nonnull' [core.NonNullParamChecker]
warning: Null pointer passed to 2nd parameter expecting 'nonnull' [core.NonNullParamChecker]
warning: argument 1 null where non-null expected [-Wnonnull]
warning: argument 2 null where non-null expected [-Wnonnull]
warning: comparison of unsigned expression in '< 0' is always false [-Wtype-limits]
warning: null argument where non-null required (argument 1) [-Wnonnull]
```
Also drop `if ... can be linked` feature checks that were identical to
`if ... is compilable` checks, for:
`closesocket`, `ioctlsocket`, `socket`, `freeaddrinfo`, `getaddrinfo`,
`gethostname`, `getpeername`, `getsockname`,
`CloseSocket` (AmigaOS), `IoctlSocket` (AmigaOS).
Another option is to really do the link checks. But, if they weren't
missed so far, it seems safer to drop than risk a detection failure,
as was the case with AmigaOS functions while working on this PR.
There remain 22 `-Wnonnull` warnings in `gethostbyname_r()`,
`getpeername()` `getsockname()`. Most of the rest is necessary for
detection, or originate from autotools and CMake detection code
templates. Some still fixable, like duplicate libs.
