Subject: parted: Escape printed device path in machine mode
References: bsc#1066467
Patch-mainline: submitted, 2017-11-07
The function _print_disk_info() uses the colon ':' as the separator
but the device path it prints can contain that character as well.
In that case parsing fails.
So introduce the function _escape_machine_string() to allocate an
output string twice as big as the input string and escape ':' and
'\' with a '\'. Print the escaped path and free it again. Ignore
the NULL pointer dereference in out-of-memory situation like it
is done for the other allocations in _print_disk_info() as well.
Resolves: bsc#1066467
