Prepare git credential to read input with DOS line endings

This contribution came in via Git for Windows
[https://github.com/git-for-windows/git/pull/2516].

Sadly, I did not find the time to go through all the changes of 8f309aeb ("strbuf: introduce strbuf_getline_{lf,nul}()", 2016-01-13) (as Junio asked
[https://public-inbox.org/git/[email protected]]).
Rather than delaying this patch indefinitely, I admit defeat on that angle.

Changes since v1:

* Added a commit to adjust credential-daemon and credential-store in the same manner.
* Adjusted the documentation accordingly.

Nikita Leonov (3):
credential.c: fix credential reading with regards to CR/LF
credentials: make line reading Windows compatible
docs: make notes regarding credential line reading
