Summary:                    Couple more bugs in gethostbyname() (patch attached)
Description: 
The following bugs have been observed in gethostbyname():

1. gethostbyname() fails if DNS server returns more than 23 addresses
(reported by me as 0001361)

2. gethostbyname() fails if the response from DNS server is truncated
(i.e. the full response would contain more than 512 bytes). Such situation
existed for a couple days for vpn.corbina.net - DNS was returning 29
addresses.

3. The h_aliases[0] field of struct hostent points to a corrupted buffer
(the buffer is always overwritten by h_addr_list[0]).

The attached patch fixes the issue for uClibc-0.9.29. Note: this patch
makes my fixes of 0001361 redundant.
