Just to underscore how we treat each other in this project. Nothing new
really, but could be useful for newcomers and outsiders to see our
values.

Flush the header stream when -D is used so that they are sent off
earlier.

Since we do prefix match using given header by application code
against header name pair in format "NAME:VALUE", and VALUE part can
contain ":", we have to careful about existence of ":" in header
parameter.  ":" should be allowed to match HTTP/2 pseudo-header field,
and other use of ":" in header must be treated as error, and
curl_pushheader_byname should return NULL.  This commit implements
this behaviour.

Following the fix made in 903b6e05.

by those versions, and to use an alternate backend like OpenSSL instead.

... in commit curl-7_43_0-18-g570076e8

In 3013bb6b I had changed cookie export to ignore any-domain cookies,
however the logic I used to do so was incorrect, and would lead to a
busy loop in the case of exporting a cookie list that contained
any-domain cookies. The result of that is worse though, because in that
case the other cookies would not be written resulting in an empty file
once the application is terminated to stop the busy loop.

libcurl can still be built with it, even if the tool is not. Maintain
independence!

It is similar to existing CURL_CFLAG_EXTRAS, but for
extra linker option.

Make sure that the error buffer is always initialized and simplify the
use of it to make the logic easier.
