Gcrypt deprecates functions by some reason, and VLC in that case should use
alternative functions, provided by libgcrypt.
They usually don't break ABI blindly until some time pass and surely they
provide alternative functions for deprecated one.
Currently there is no usage of deprecated libgcrypt functions in VLC core
and modules.
Note that future release of libgcrypt (1.6.0) will not be ABI compatible
with previous versions because of removal deprecated functions.

IMHO it is better to break during development process and fix usage of
deprecated functions early, then fixing it after real users note that
something gone wrong after updating libgcrypt library.
