core: Fix unused variable warnings on release builds
The recently introduced PTHREAD_CHECK and WINAPI_CHECK macros cause a
large number of compiler warnings for unused variables on release
builds. Fix this by implementing those macros in terms of some new
macros that are defined based on the definition of NDEBUG.
Closes #788
