gpllib: Add parse_partition_table() to iterate through all partitions on a disk
Impact: expand gpllib disk API
parse_partition_table() can be used to execute a callback on each partition.
The signature of the callback is:
void callback(struct driveinfo *drive_info,
struct part_entry *ptab,
struct part_entry *ptab_root,
int offset_root,
int local_partition_number,
int ebr_seen)
* drive_info represents the disk.
* ptab is the current partition entry processed.
* ptab_root is the partition entry linking to the current one processed (extended only).
* offset_root is the offset of the ebr when iterating through extended partitions
(0 otherwise).
* local_partition_number is the number of the partition processed (0->3).
* ebr_seen counts the total number of ebr processed.

pxelinux: fix the handling of KeepPXE
KeepPXE was broken in 3.74, because we tried to use both bits 0 and 1,
but failed to actually test both bits. Instead, just use bit 0, but
move the place where we clear the bits.

com32: use xfer_buf_seg as the bounce buffer
We cannot realistically realign comboot_seg without breaking com16
modules (which have the DOS-derived assumption that they own the rest
of low memory.) However, we can use xfer_buf_seg as the com32 bounce
buffer, which allows us to retain the benefit of a 64K-aligned buffer.

core: don't misalign xfer_buf_seg
xfer_buf_seg is used for bulk transfers, and we really don't want
to break it up in order to avoid 64K DMA boundaries.
Note: the same is true for the com32 bounce buffer, which is
real_mode_seg. However, there are hard assumptions in the code that
real_mode_seg is the last segment; those need to be cleaned up, or we
need to verify that xfer_buf_seg can be used as the com32 bounce
buffer.

shuffler: work around KVM problem with the new shuffler
KVM uses V86 mode to simulate real mode. This causes problems with
the new shuffler. This changes the shuffler handover to be in
16-bit protected mode instead, and requires the stub to do the actual
entry to real mode. For the KVM hack to work, all segments must have:
(seg.base & 0xfff0000f) == 0 && seg.limit == 0xffff
As a result, we have to make sure the real-mode entry stub is
paragraph-aligned, lest we violate the first criterion.
