sock-redirect implements read(), recv(), etc with intention to override
them. However, some versions of glibc provide "fortified" calls. This is
implemented by making regular symbols as inline wrappers on top of
__read_chk() or similar.

gcc allows to redefine such inline wrappers with specific attributes,
but clang fails with an error.

As a workaround for clang, rename glibc wrappers on the preprocessing
stage.

Clang doesn't allow variable sized type not at the end of a struct
claiming this is a GNU extension. Make a union instead of adding an
array after the variable sized field.

This fixes vmad compilation with clang.
