[DriveSetup] add Format partition checkbox to Create partition dialog

[diver]

When creating a BFS partition it's not immediately obvious that it won't be formatted to BFS. Installer will complain about such partition even though they will be labelled as (Be File System) adding even more confusion.

Adding "Format to BFS" checkbox (enabled by default) to this dialog could avoid the confusion:

Installer should also mark unformatted partitions somehow.

Do we even need a checkbox? Would it not make sense to automatically bring the user to the "filesystem initialization" dialog? Which can be cancelled anyway.

The checkbox will avoid additional "filesystem initialization" dialog.

The filesystem initialization dialog cannot be skipped completely. You have to select the block size and decide wether to enable queries or not.

There are really two different steps and each with different options and dialogs possible:

1) creating the partition. Which is different on MBR vs GPT disks

2) initializing, which is different in BFS, FAT, NTFS, etc.

I don't think it's easy to completely merge the two steps then. An "assisted" mode as is found in typical Linux installers would be nice and solve a lot of the confusion. Something like "I don't care, wipe everything from the disk and set it up however you want". But we should keep the existing dialogs for more advanced cases.

However, creating a partition and then not formatting it is quite useless, so chaining partition creation and initialization would make sense. Except there is currently no way to map a partition type (which is only informative and only exists for MBR anyway) to a filesystem, so we should add that too.

The filesystem initialization dialog cannot be skipped completely. You have to select the block size and decide wether to enable queries or not.

It should be merged into one dialog. Creating partition without formatting makes no sense (if it is really needed, RAW file system can be selected). The same behavior is done in Windows diskmgmt.msc.

Move unsolved issues to beta 4 since there is no chance of fixing them now.

Moving various tickets out of the beta4 milestone because no one is actively working on them.
