Follow-up to 3463408.
Prior to 3463408 file:// hostnames were silently stripped.
Prior to this commit it did not work when a schemeless url was used with
file as the default protocol.

Closes https://github.com/curl/curl/pull/1124
Also fix for drive letters:
- Support --proto-default file c:/foo/bar.txt
- Support file://c:/foo/bar.txt
- Fail when a file:// drive letter is detected and not MSDOS/Windows.

- Call Curl_initinfo on init and duphandle.
Prior to this change the statistical and informational variables were
simply zeroed by calloc on easy init and duphandle. While zero is the
correct default value for almost all info variables, there is one where
it isn't (filetime initializes to -1).
