In order to consolidate the installer option-parsing system,
we add the --mbr (-m), --active (-a), and --force (-f)
options from the DOS, Win32, and mtools installers to
libinstaller.
Since the -m and -a options are not currently valid for the
Linux 'syslinux' and 'extlinux' installers, we add error
messages to both of these. The -f option is allowed but
does nothing for them.

It appears that the glibc version of asprintf() is braindamaged, and
doesn't set the target pointer to NULL in the event of an error (only
returns -1). Therefore we need to check the return value. Just in
case someone else made the *opposite* error, also check the pointer.
Bleh. The glibc documentation states that *BSD sets the pointer to
NULL, but instead of following that, the glibc people put
warn_unused_result on asprintf. Sigh.

Reduce sector 1 space pressure by moving objects that aren't needed by
Sector 1 proper into an "extended patch area". While we're mucking
with the installer code, make the syslxint and extlinux installer code

Switch to consistent use of 64-bit sector pointers; this should enable
booting even for individual *partitions* larger than 2 TB. In order
to not slow down the boot too much, switch the initial load from an
enumeration to an extent map. This means the table gets larger (since
we have to assume the worst case), but it simplifies the Sector 1 code
(since we can push all the hard stuff into the installer), and will
speed up booting in the general case.

Implement the !GPT handover protocol in the Syslinux core, and handle
partition offsets above 2 TB. We do not yet handle filesystem sizes
above 2 TB, but that should be a reasonably straightforward extension
at this time (need to switch to 8-byte block pointers).
This finally meant moving getlinsec out of the boot sector, since it
no longer fits. Instead have a very simple getonesec implementation
in the boot sector. getlinsec still fits in Sector 1, although it
doesn't leave space for very many block pointers. That's still better
than adding yet another boot loader stage, however.

The previous merging extlinux/syslinux patch is not sufficient, the
syslinux is not real "patchbased", hence:
* fill currentdir in patcharea
* search "extlinux.conf" and "syslinux.cfg" for generic_load_config
* define boot_image and boot_sector macro for ldsyslinux
this could make further merging extlinux and syslinux possible

Work on picking the initial cwd by storing a path instead of by
storing an inode number. This should be both more general (in the
sense of supporting filesystems in a generic way) as well as
conceptually cleaner. The code doesn't work yet, but this at least
provides support for the extlinux installer to store its subpath into
the installed image.

Additional fixes for the 32K limits in the installers. In the case
of the DOS installer, that means changing it from COM format to EXE
format (since COM format has a 63K hard limit); retain the name
syslinux.com for user compatibility, though (DOS doesn't care what the
extension except for pathname search; if it finds an MZ EXE header it
will use it.)
With the change to EXE means having to handle more than one segment.
Since we don't have a real DOS compiler we have to wing it a bit.
