default to 1MiB alignment when possible
Change the linux_get_optimum_alignment() function to prefer
aligning partitions to PED_DEFAULT_ALIGNMENT (1MiB), if possible.
This helps tools like anaconda better support 4k sector drives.
* include/parted/parted.h (PED_DEFAULT_ALIGNMENT): Define.
* libparted/arch/linux.c (linux_get_optimum_alignment): Adjust.
See comments for details.
* libparted/device.c (ped_device_get_optimum_alignment): Use
PED_DEFAULT_ALIGNMENT rather than hard-coded 1048576.
* tests/t9020-alignment.sh: Adjust expectations to match new behavior.
See http://bugzilla.redhat.com/618255 for details.
