torrc parsing b0rks on carriage-return

(Specifically, carriage return after a quoted value in a config line. Fixes bug 19167; bugfix on 0.2.0.16-alpha when we introduced support for quoted values. Unit tests, changes file, and this parenthetical by nickm.) --- changes/bug19167 | 4 ++++ src/common/util.c | 2 ++ src/test/test_util.c | 31 +++++++++++++++++++++++++++++++ 3 files changed, 37 insertions(+)
