Previously, there were technically definitions for Dev_Random in both server.c and numbers.c, as well as everywhere else that included server.h. GCC seems to've either been previously correcting or masking this issue, or perhaps Dev_Random just doesn't get used in practice outside of where it's set in server.c, so it never had a chance to cause issues. At some point, GCC switched to not silently merging the conflicting definitions without -fcommon, which isn't recommended to use in practice. Whatever the case, set the declaration in server.h extern, remove unnecessary declaractions, and actually define Dev_Random in server.c (to match server.h) so that there is one definition that is referenced everywhere. Fixes necanthrope#9

GCC versions above 10.0 use -fno-common instead of -fcommon. The change in default operation for GCC 10 prevented the project from building because of how the Dev_Random file pointer was defined, as it was being defined multiple times per the compiler.
