Suggestion: Removal of BIND from base / Import alternative DNS Library ldns / import dig replacement drill

[Jan Lentfer]

Dear all,

I have lately been busy working on ripping BIND out from contrib and 
base. I entirely remove BIND from contrib/ and moved the necessary files 
for libresolv into lib/libc so libc still builds and works.

By removing BIND also all the related tools (host, nslookup, dig and 
others) are gone. To still provide a tool to make DNS queries I decided 
to put "drill" into base. This is a dig replacement that should be 
option- and output-equal to BIND's dig.

This made it necessary to also import the alternative DNS Library ldns 
(in which drill is included). In a second step ldns could also give us 
the opportunity to also make libc independent for BINDs resolver as it 
should provides it'S own resolver library. I guess all that needs to be 
done is to interface the res_* stuff from BIND to ldns.

Enough words, necessary links:

Please let me know what you think about his approach.
