replacing strbuf_getline_lf() by strbuf_getline()

Although I was not sure [4], I decided to roll out v4, in the hope that the next reviewers will profit by the more polished commit messages and order.

This series deals with strbuf_getline_lf() in certain codepaths:
Those, where the input that is read, is/was trimmed before doing anything that could possibly expect a CR character. Those places can be assumed to be "text" input, where a CR never would be a meaningful control character.

The purpose of this series is to document these places to have this property, by using strbuf_getline() instead of strbuf_getline_lf(). Also in some codepaths, the CR could be a leftover of an editor and is thus removed.

Every codepath was examined, if after the change it is still necessary to have trimming or if the additional CRLF-removal suffices.

The series is an idea out of [1], where Junio proposed to replace the calls to strbuf_getline_lf() because it 'would [be] a good way to document them as dealing with "text"'.

Changes since v3 [3] (the changes to single patches are indicated below):

* Commit messages refined
* Order of patch 4 and 5 in v2 was switched.

The interdiff only removes an empty line (I noticed, when changing the order of commits, that the splitting operation had no newline before this whole series, so I left it that way):
