Errors during build if VIO_DEBUG is uncommented in vio_debug.h

[kmatveev]

Branch v5.0-release

If definition of VIO_DEBUG is uncommented in vio_debug.h , then build fails.

Following error message is issued during make_boot.bat DEBUG

11>..\..\..\src\jrd\vio.cpp(4999,67): error C2065: tail_length: unknown identifier [c:\firebird-build\builds\win32\msvc15\engine_static.vcxproj]

If this error is fixed, then make_boot.bat DEBUG is completed without errors. However, there will be lots of "missing symbol" linkage error during make_all.bat DEBUG. These errors are caused by several generated files, for example gen/alice/alice_meta.cpp , having length of 0.
I've tried to reproduce code generation step manually by running GPRE, to see it failing with access violation. Running it with debugger attached caused it to catch error with following stack trace:
