Removed case clause for length = 0 for both HTTP1.0 and HTTP1.1
Fix doc typos for R16B01
Include module, function and arity in Dialyzer's "overlapping domain" warnings

The function name can give information that the line number doesn't,
for example when using a parse transform that creates new functions.
Fix cover.xml formatting error
Document change to cover.erl source search

The change was introduced in commit 29231033.
Extend cover.erl source search

Commit 29231033 made cover fall back to compile info if source was not
found in pwd or ../src. This isn't sufficient for source that lies in
subdirectories of ../src when beams and source have been moved since
compilation (eg. install of some OTP applications), so first try finding
source relative to the beam directory.

For example, given a beam path

  /installed/path/to/app-1.0/ebin/root.beam

and a source path

  /compiled/path/to/app/src/subdir/root.erl

then look for

  /installed/path/to/app-1.0/ebin/../src/subdir/root.erl

before the source path.
