821775e983 Fix parsing of -A option so that the [/ptn_0_offset] part is optional, as 
described in the man page.

4d8b353d15 Put #endif in correct place - fixes PR/42500 
Update usage() for -A, and rename one of the variables for clarity.

9193c05dda Add support for partition being aligned on non-cylinder boundaries. 
Info can be specified with -A parameter.
Default is based on how the first partition is defined.
For empty disks larger than 128GB (arbitrary figure) use 1MB alignment.

795733c59e Add a large comment about disk geometries. 
Rename (with #defines) the variables use for aligning partitions to
separate them from the bios geometry.
All in advance of allowing other partition alignments (eg 2048 sectors).

6c1041b8b7 So that we can build a full-featured fdisk cross-tool with -DBOOTSEL, 
condition the definition of DEFAULT_BOOTxxx variables and SCAN_xxx
on defined(BOOTSEL), instead of defined(__i386__) || defined(__x86_64__).

While I'm here, only build get_diskname in the same conditions as
get_geometry is built, since only the latter calls the former.

opendisk() declared in that file is not used in this case anyway, and
