Silence compiler warnings on clang 21

Clang 21 shows some new compiler warnings, for example:

warning: variable 'dstsize' is uninitialized when passed as a const pointer argument here [-Wuninitialized-const-pointer]

The fix is to initialize the variables when they are defined.  This is
similar to, for example, the existing situation in gistKeyIsEQ().
