Previously the curl_multi interface would freeze if darwinssl was
enabled and at least one of the handles tried to connect to a Web site
using HTTPS. Removed the "wouldblock" state darwinssl was using because
I figured out a solution for our "would block but in which direction?"
dilemma.
Replaced the Windows real path from mount hack with a more
reliable and simpler hack: the MSYS shell has a builtin pwd
which understands a -W option which does convertion to Windows
paths. Tested and confirmed that this works on all MSYS versions
I have back to a 3 year old one.
In many states the easy_conn pointer is referenced and just assumed to
be working. This is an added extra check since analyzing indicates
there's a risk we can end up in these states with a NULL pointer there.
I made "connmon" not get initialized properly before use, and I use the
big hammer and make sure we always clear the entire struct to avoid any
problem like this in the future.
Two commits ago, we fixed a bug where the connction would be closed
prematurely after a HEAD. Now I added connection-monitor to test 48 and
added a second HEAD and make sure that both are sent over the same
connection.
This triggered a failure before the bug fix and now works. Will help us
avoid a future regression of this kind.
This makes verifying easier and makes us more sure curl closes the
connection only at the correct point in time. Adjusted test 206 and 1008
accordingly and updated the docs for it.
A HEAD response has no body length and gets the headers like the
corresponding GET would so it should not get closed after the response
based on the same rules. This mistake caused connections that did HEAD
to get closed too often without a valid reason.

1 - str2offset() no longer accepts negative numbers since offsets are by
nature positive.
2 - introduced str2unum() for the command line parser that accepts
numericals which are not supposed to be negative, so that it will
properly complain on apparent bad uses and mistakes.
