OpenID code fails when CURL is not installed

[webmaster]

The current OpenID class requires the CURL module to be installed, to access SSL sites with certificate checking.

Enabling OpenID on a site that doesn't have CURL cases the class to terminate, which makes p.e. the edit_profile module crash.

Workaround and extra checks implemented in changeset [1978]: set the default authentication method for new installations to "Local database" only. added checks on the availability of the cURL library. If not present, OpenID will be disabled.

Leaving the ticket open because we need to replace the OpenID library by something that doesn't require external PHP modules

Created a fix for this problem using libcurlemu, with utilizes the cURL commandline tool if present, or emulating cURL in PHP if all else fails.

Don't have a PHP installation available without cURL linked in, so I can't test it.

Asked the user who reported the problem to test the fix, before I include it in the code.

Feedback from the user:

cURL emulator module fixed the error message, but unfortunately the OpenID library is not compatible with the emulator.

This idea is scrapped then, and a requirement for libcurl has been added to the wiki (only if OpenID authentication is required).
