Makes our error coverage a little more consistent across the board by applying it to Linux side of things as well. This also makes it more consistent with the warning settings in other libraries in the project. This also updates httplib to 0.7.9, as there are several warning cleanups made that allow us to enable several warnings as errors.

/* Quote from RFC2818 section 3.1 "Server Identity"
|
|
|
|
If a subjectAltName extension of type dNSName is present, that MUST
|
|
be used as the identity. Otherwise, the (most specific) Common Name
|
|
field in the Subject field of the certificate MUST be used. Although
|
|
the use of the Common Name is existing practice, it is deprecated and
|
|
Certification Authorities are encouraged to use the dNSName instead.
|
|
|
|
Matching is performed using the matching rules specified by
|
|
[RFC2459]. If more than one identity of a given type is present in
|
|
the certificate (e.g., more than one dNSName name, a match in any one
|
|
of the set is considered acceptable.) Names may contain the wildcard
|
|
character * which is considered to match any single domain name
|
|
component or component fragment. E.g., *.a.com matches foo.a.com but
|
|
not bar.foo.a.com. f*.com matches foo.com but not bar.com.
|
|
|
|
In some cases, the URI is specified as an IP address rather than a
|
|
hostname. In this case, the iPAddress subjectAltName must be present
|
|
in the certificate and must exactly match the IP in the URI.
