installer: partionment: Add encryption support.
* gnu/installer.scm (set-installer-path): Add cryptsetup. * gnu/installer/newt/partition.scm (prompt-luks-passwords): New procedure, (run-partioning-page): Add the possibility to set encryption to "On" on a partition and choose a label, add a new partition scheme: "Guided - using the entire disk with encryption", prompt for encryption passwords before proceeding to formating. * gnu/installer/parted.scm (<user-partition>)[crypt-label], [crypt-password]: New fields, (partition-description): add the encryption label, (user-partition-description): add an encryption field, (auto-partition): add two partitioning schemes: entire-crypted-root and entire-crypted-root-home, (call-with-luks-key-file): new procedure, (user-partition-upper-path): new procedure, (luks-format-and-open): new procedure, (luks-close): new procedure, (format-user-partitions): format and open luks partitions before creating file-system. (mount-user-partitions): use the path returned by user-partition-upper-path, (umount-user-partitions): close the luks partitions, (user-partition->file-system): set device field to label for luks partitions and to uuid for the rest, (user-partition->mapped-device): new procedure, (user-partitions->configuration): add mapped-devices field.
