    Fix compilation errors in MSVC
    
    EncryptTest: Fixed test with macro non compiling in MSVC
    StringTest: Removed use of VLA to fix MSVC compilation
    podofocrop: Fix get_ghostscript_output compilation on MSVC with UNICODE builds
                Just switch use of CreateProcess to specific ANSI version CreateProcessA
    podofosign: Fix compilation error including libidn in MSVC
