pyuv >= 1.0.0 has 'getaddrinfo()' in 'dns' module

[Ed-von-Schleck]

From the first stable version on, pyuv has moved the 'getaddrinfo()' function from the 'util' module to the 'dns' module. This patch reflects this change.

If wanted for, I could modify it to fall back to 'util' when an import error occurs (just to preserve backwards compatibility), though I'd rather not.

getnameinfo, defined just below, was moved in the same way. FWIW, I'd go for requiring pyuv >- 1.0.0, since that will be supported long term with backwards compatible API changes.

[Ed-von-Schleck]

Thanks; I added this one as well.

Maybe you could add another commit fixing the dependency here: https://github.com/geertj/gruvi/blob/master/requirements.txt

[Ed-von-Schleck]

Thanks again; I removed the direct github download as well in favour of using pypi.

LGTM, but this is @geertj's project :-)

PS: The travis failure seems unrelated, FWIW.

[geertj]

Thanks @Ed-von-Schleck and @saghul! The Travis error appears related to the SSL changes in 2.7.9, not to this commit. Looking into it now.

[geertj]

The patch is good. The test failure is indeed an issue with the SSL changes in 2.7.9. Will fix those later tonight.

SSL in 2.7.9 has been fixes as well (in 274a798)
