Avoid conflict between contrib/uuid and system uuid
glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.
