typecheck: accept expressions for option/info parameters
As expressions can have side effects, evaluate only once.
To enable deprecation reporting only once, get rid of the __typeof__
use to define the local temporary variable and use the target type
(CURLoption/CURLINFO). This also avoids multiple reports on type
conflicts (if some) by the curlcheck_* macros.
Note that CURLOPT_* and CURLINFO_* symbols may be deprecated, but not
their values: a curl_easy_setopt call with an integer constant as option
will never report a deprecation.
