Remove "big endian" DNS section and RR data integer parser macros from

ares_dns.h, which break c-ares on my Sparc64. Bit-wise operations in C
operate on logical values. And in any event the octets are already in
big-endian (aka network) byte order so they're being reversed (thus the
source of the breakage).

- William Ahern handles EAGAIN/EWOULDBLOCK errors in most of the I/O calls
