FILE: fix CURLOPT_NOBODY and CURLOPT_HEADER output

2018-10-08T06:35:40+00:00

Now FILE transfers send headers to the header callback like HTTP and
other protocols. Also made curl_easy_getinfo(...CURLINFO_PROTOCOL...)
work for FILE in the callbacks.

Makes "curl -i file://.." and "curl -I file://.." work like before
again. Applied the bold header logic to them too.

Regression from c1c2762 (7.61.0)

Fixes #3083
Closes #3101

Tests: fixes for Windows

- test 1268 requires unix sockets
- test 2072 must be disabled also for MSYS/MinGW

file: restore old behavior for file:////foo/bar URLs

2018-04-06T12:28:42+00:00

curl 7.57.0 and up interpret this according to Appendix E.3.2 of RFC
8089 but then returns an error saying this is unimplemented. This is
actually a regression in behavior on both Windows and Unix.

Before curl 7.57.0 this URL was treated as a path of "//foo/bar" and
then passed to the relevant OS API. This means that the behavior of this
case is actually OS dependent.

The Unix path resolution rules say that the OS must handle swallowing
the extra "/" and so this path is the same as "/foo/bar"

The Windows path resolution rules say that this is a UNC path and
automatically handles the SMB access for the program. So curl on Windows
was already doing Appendix E.3.2 without any special code in curl.

Regression

Closes #2438
