fdisk: move DOS new/add partition code Since this is DOS specific logic, it belongs in its own label file. Additionally, a dos_new_partition() function is created that asks the user for partition type and then calls the actual dos_add_partition(). This patch passed fdisk regression tests, builds without problems and it was locally tested against adding and removing DOS partitions. Signed-off-by: Davidlohr Bueso <dave@gnu.org>

fdisk: use context as a parameter This program heavily uses global variables, which isn't very elegant and can lead to nasty bugs. Modify functions that use fdisk's context current features (descriptor and path), to receive the context as a parameter instead of globally. This includes DOS, SUN, SGI and BSD label code. Another benefit that comes with this is that as the API grows all the information regarding fdisk will be accessible from this structure so we can reduce even more global variables and simply code. This patch passed: - building - regression tests - local dos/sun/bsd partition changes Signed-off-by: Davidlohr Bueso <dave@gnu.org>

fdisk: add device topology to the API This patch adds device topology discovery to the internal API. This functionality is static only to the API and therefore hidden from general fdisk code. Functionality itself doesn't really change, min_io_size, io_size, logical and physical sector sizes and alignment offset are added to the fdisk_context structure and elements are accessed from there. The logical sector size (sector_size) is now unsigned long instead of unsigned int, this as no effect otherwise. A few things to notice: - The patch is larger than I wanted but we need to modify function parameters across fdisk and its labels to use the topology data from cxt-> instances. Hopefully this will be pretty much it regarding this kind of modifications - perhaps geometry will need something of the like too. - The -b option must override internal discovery. - A new helper function has added to verify if the device provides topology information, this replaces the 'has_topology' global variable.

fdisk: API: add geometry Add device geometry to the fdisk API. While it maintains traditional behaviour, the cylinders are changed to sector_t instead of unsigned int in order to avoid dealing with truncated cylinders. A new helper is added to compute the amount of cylinders based on the heads and sectors - if a user passed -H or -S to the program, it must call this function to update the corresponding values. This patch passes regression tests. Signed-off-by: Davidlohr Bueso <dave@gnu.org>

fdisk: isolate dos label logic DOS specific logic is currently embedded in the heart of fdisk code. This patch separates DOS label specific code into its own file, just like the rest of the labels, leaving a more generic fdisk.c file. Most changes are just moving code from fdisk.c to fdisk.h and fdiskdoslabel.[c/h]. The only logical modification is calling dos_delete_partition() from read_extended(), instead of the generic delete_partition. This is ok since read extended is only called from a DOS context.
