Write Support in the Intel Partitioning Module

[bonefish]

Implement the missing write support in the intel partitioning module (src/add-ons/kernel/partitioning_systems/intel).

[stippi]

Removing form the R1/alpha1 milestone, for the same reasons as #1822. Actually, write support is there for the features we need (initializing partitions). The most important problems are:

1) Retrieving possible disk system candidates for completely empty volumes. Currently, an empty harddrive can be initialized with BFS, but the BDiskDevice methods to retrieve disk systems do not work, since a proper object hierarchy is not being setup in the kernel.

2) Write support in the Intel Extended Partition. The Intel Partition Map write support could actually work already, but needs proper testing.

Replying to stippi:

2) Write support in the Intel Extended Partition. The Intel Partition Map write support could actually work already, but needs proper testing.

What and how can this be tested?
