Title:
  Cannot include "netinet/in.h" with "linux/netfilter/nf_nat.h" and
  "sys/capability.h"

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I expect to be able to compile the following program (and indeed I am
  able to compile it on Ubuntu release before 15.10):

  ```
  // test.c
  #include "sys/capability.h"
  #include "netinet/in.h"
  #include "linux/netfilter/nf_nat.h"

  int main() {
    // Program that needs to call capset() and htonl(), and also needs
    // to do some netfilter things with NF_ACCEPT...
  }
  ```

  However, on 15.10 I get a bunch of errors:

  
  ```
  $ gcc test.c
  In file included from test.c:3:0:
  /usr/include/linux/in.h:28:3: error: redeclaration of enumerator ‘IPPROTO_IP’
     IPPROTO_IP = 0,  /* Dummy protocol for TCP  */
     ^
  /usr/include/netinet/in.h:42:5: note: previous definition of ‘IPPROTO_IP’ was here
       IPPROTO_IP = 0,    /* Dummy protocol for TCP.  */
       ^
  ...
  ```
