- cmake: fix compiler warnings in `CheckNonblockingSocketSupport`. detection functions. Without this, these detections fail when `ENABLE_WERROR=ON`. - cmake: disable ENABLE_WERROR for MSVC during symbol checks in `src`. CMake's built-in symbol check function `check_symbol_exists()` generate warnings with MSVC. With warnings considered errors, these detections fail permanently. Our workaround is to disable warnings-as-errors while running these checks. ``` CheckSymbolExists.c(8): warning C4054: 'type cast': from function pointer '__int64 (__cdecl *)(const char *,char **,int)' to data pointer 'int *' in `return ((int*)(&strtoll))[argc];` ``` Ref: https://ci.appveyor.com/project/libssh2org/libssh2/builds/46537222/job/4vg4yg333mu2lg9b - example: replace `strcasecmp()` with C89 `strcmp()`. To avoid using CMake symbol checks in `example`. Another option is to duplicate the `check_symbol_exists()` workaround from `src`, but I figure it's not worth the complexity. We use `strcasecmp()` solely to check optional command-line options for example programs, and those are fine as lower-case. Without this, these detections fail when `ENABLE_WERROR=ON`. - also delete `__function__` detection/use in `example`. To avoid the complexity for the sake of using it at a single place in of the example's error branch. Replace that use with a literal name of the function. - cmake: also use `CMakePushCheckState` functions instead of manual save/restore. Closes #857
