Some ISO C fixes

This patch just fixes a limited number of bits not conforming to c99 by using
 - __asm__ instead of just asm
 - {0} instead of {} for struct initialization
 - h_addr_list[0] instead of h_addr to access the host address in
   struct hostent
 - #include <strings.h> where needed (for ffs and strcasecmp)

Based on a previous patch by Carl-Daniel.

Corresponding to flashrom svn r1585.
