Coding Style is not consistent

[andrewhit]

The coding style in dpvs is not consistent.

For example, one whitespace is added or missing between "if" and "(".

neigh.c:198: if(!(neighbour->flag & NEIGHBOUR_HASHED)){
vlan.c:517: if (!conf || size < sizeof(*param) || !out || !outsize)

Some line exceeds the column number, 80. For example, dpvs/tools/dpip.

106 inet_ntop(neigh->af, &neigh->ip_addr, ipaddr, sizeof(ipaddr)) ? ipaddr : "::",

Or whether "{" should be added after "if ()" for the single statement.

The tool of "uncrustify" does the code beautification for your info.

It is better to add some coding style guideline to DPVS repo.

The auto check script/tool should be added to CI at the very beginning of project.
We'll perform more strict standard for review, and to see if we can hook some auto-check script to CI in the future.
