This makes symbols defined in com32.ld and syslinux.ld HIDDEN, to
avoid collisions.  Additional linker scripts should have this done, too.

If we have hardwired DHCP options, move them into high memory instead
of into the trackbuf.  This eliminates yet another trackbuf user.

We don't actually have any constructors/destructors in the core at
this time, but handle .init/fini_table in case that happens...

We don't need to use a special aux segment because we can represent
'fontbuf' with OFFS() and SEG(). We're guaranteed to be able to break
the 32-bit pointer up with these macros because we control where in
the address space the core is loaded. (Not all 32-bit pointers can be
represented with OFFS() and SEG(), only addresses in the range
0..0xFFFFF.)

This fixes the breakage that was introduced in commit 14531c47bc95
("core: Delete code that is duplicated in ldlinux").

This allows the default font to be displayed. Previously junk was
being returned in the COMBOOT API call to query the userfont, leading
the caller to believe that a user font was installed even when it
wasn't.

The EFI firmware loader might place syslinux.efi anywhere in RAM, we
can't assume that base addr of core_module is 0x0 to initialise it at
runtime with the correct value.

Also, using __dynsym_len doesn't seem to work properly with
syslinux.efi so calculate the length at runtime.

There are no more users of the .hugebss section, so remove it from
existence.
