Quantum a380803d37 [client] libdecor: fix gcc compile warnings-turned-errors
This commit fixes the -Wmissing-field-initializers warning, which can only
be disabled with a pragma. GCC wants us to Initialize libdecor reserved
fields, which requires knowing how many reserved fields there are.
This is an implementation detail, and so we can only disable the warning.

This also fixes -Wincompatible-pointer-types, which is an actual bug.
