Instead of symlinks and build-time configuration the ipaplatform module
is now able to auto-detect platforms on import time. The meta importer
uses the platform 'ID' from /etc/os-releases. It falls back to 'ID_LIKE'
on platforms like CentOS, which has ID=centos and ID_LIKE="rhel fedora".
The meta importer is able to handle namespace packages and the
ipaplatform package has been turned into a namespace package in order to
support external platform specifications.

When writing extracted certs and keys to the file, we opened the
same file at a different spot but the original file position
indicator would not be moved when the certificate is written there.
The result is that the certificate gets rewritten by the private
key. This commit fixes it.

CA certificates MUST have the Subject Key Identifier extension to
facilitiate certification path construction. Not having this
extension on the IPA CA certificate will cause failures in Dogtag
during signing; it tries to copy the CA's Subject Key Identifier to
the new certificate's Authority Key Identifier extension, which
fails.
When installing an externally-signed CA, check that the Subject Key
Identifier extension is present in the CA certificate.
