Fixes cookie domain specification

if the domain given in HTTP_HOST variable happens to have a port
specification. Technically, the port specification should not be included in
the domain spec given in the cookie.

(And for the record, that makes no sense to me, seeing as a cookie would
otherwise be valid for all servers on any ports at a particular domain).
Avoid double-encoding thread titles

This is safe now, because the title is appropriately encoded in
class.thread.php/ThreadEntry::create()

Fixes #567, #718
Fixes ROOT_PATH detection on Windows

Also converts ROOT_DIR detection to always use forward slashes. And it fixes
the removal of the leading double-backslash on Windows UNC names (fixes #649)

Fix 1.6-* upgrade to 1.7.1

8e72e521d48ca04fd8db7d05318e2c55b9b2d278 (v1.7.1.2+) introduced a bug where
osTicket version 1.6 would not send a cookie (by calling PHP
session_start()) for the login page. Therefore, after unpacking the 1.7.1
source code, an upgrade would not be possible, because a login would never
be processed correctly.

Detect attachments with Content-Type: ...; name=

RFC2045, section 5.1 seems to indicate that arbitrary parameters can be
appended to a Content-Type header specification. Some email clients seem to
use the Content-Type header to specify an attachment without giving a
separate Content-Disposition header normally used to signify attachments.

This patch corrects attachment detection for piped emails to detect such
emails. The patch also correctly decodes filenames specified either in the
Content-Disposition or Content-Type headers using RFC5987, where the
filename can be encoded using an arbitrary character set (ie, not us-ascii).
