Andr�s Garc�a found out that Curl_protocol_connect() could return an
uninitialized variable.

Wez Furlong's curl_version_info() function added, still needs some
adjustments and possibly some improvments to feature all those things we
could possibly want from this.

5 changes since pre3

made the resume error more suitable for all protocols, but we provide a
fallback to the old ftp-one to make old programs work the same

fix resume when multiple files were specified

spell fix comment

removed use of extra unneeded variable

Dolbneff A.V and Spiridonoff A.V made the file:// code work with resumes
in the same style other code does.

properly disconnect failed connections

Craig Markwardt made the "struct hostent_data" get cleared too, as is
needed on Tru64 (or something).

Re-ordered all the options to be more logically structured. Hopefully this
will make this page more readable and easy to find things in!

a follow-up fix to the previous fix for HTTP servers that don't reply *any*
headers at all

better deal with HTTP(S) servers that respond with no headers at all, test
case 306 added to verify that we do right

clarified what CURLOPT_MAXCONNECTS actually do

306 added

request a page from HTTPS but get no headers

recent fixes

Lukasz Czekierda correctly pointed out that curl used a bad Host: header
when talking to a IPv6-server using IPv6 IP address only.

ignore html files here

added more recent return codes

filled in the -k text too

added -k for 7.10, added some more details on -y based on comments from
Kingsley Morse

remove redundant comment
