to an undefined value for some large SCSI devices when

* ahci: Fix VPD page reporting so that it does not return
undefined values
* ahci: Set the write bit to true when sending a DATA SET

This also keeps the functionality of hrev53848, which simplifies the
list of disks searched for bootable partitions; however, it maintains
the previous behaviour of platform_get_boot_partitions that continues
to iterate over a list of possible boot partitions, which should
allow finding a bootable BFS partition better in more circumstances.
Particularly, there are numerous reports of the UEFI loader entering
the boot menu despite it finding a bootable partition, which this
should address.
EFI's device_contains_partition is also structured such that it
compares the disk GPT table of the partition the loader is
querying of the EFI disk's GPT table, in the case that there are
multiple disks, as the most reliable method of comparison, with
a generic fallback for non-GPT disks, which will be less reliable.

Previously, BUrlRequest returns data received via a callback that can't
return any value. This approach have several issues:
- It's not possible to signify failures to the request.
- Users have to implement custom listeners just to handle the common
case of outputting to a buffer/file/etc.
- The received data has to be serialized into BMessage when
BUrlProtocolDispatchingListener is employed. This can cause a
noticible slowdown in real-world scenarios as evident by #10748.
With this change, BUrlRequest will output directly into a BDataIO, which
exposes a richer API for request handlers to work with (for example a
BitTorrent client can request a BPositionIO for non-linear data
delivery), as well as simplifying common cases for users.
The adaptation only requires one additional API:
BHttpRequest::SetStopOnError(). This API simply instructs the HTTP
request handler to cancel the request if an HTTP error is occurred.

The switch to make BUrlResult serializable was debuted in
f9e1854f19 with the rationale is that
BHttpRequest auto-redirection might cause the headers to become
obsolete by the time a client process the BMessage received from
BUrlProtocolDispatchingListener.
With the change to BHttpRequest to not notify listeners when
auto-redirection is enabled, this is no longer the case and the
serialization code can go away now. This simplifies BUrlResult and its
subclasses, and gain us some performance for clients using
BUrlProtocolDispatchingListener as the result object no longer has to be
serialized.
This also change the ABI of BUrlProtocolListener::HeadersReceived to no
longer passing a BUrlResult.
Additionally, BUrlResult and BHttpResult now express the size of the content
as an off_t, thus allowing results larger than 4 GB.

The geometry is retrieved on demand in the first read or write or in a
call to the get geometry or get device size ioctl. It is not possible to
retrieve it from the device initialization because that is called as
part of the mmc_bus scanning, which needs a specific sequence of
commands and keeps the bus locked to prevent drivers to insert their own
commands in the middle of that sequence.

First implementation of reading sectors from an SD card.
This is not the best performance for many reasons:
- No DMA
- Reads only one sector at a time
- Cannot read more than 512 bytes per syscall
Also there are major limitations:
- Cannot read less than 512 bytes. The hardware of course works in full
sectors. The mmc_disk driver should go through the io scheduler to
make sure requests have a reasonable size and offset, and nothing
tries to read just a few bytes in the middle of a sector.
- SD cards only (no SDHC, no MMC)
Architecture problems:
I think too much of the implementation is done in sdhci_pci and should
be moved to the upper layers. However it is difficult to say without
having implemented DMA (which indeed will be at the low level of the
sdhci controller). It doesn't help that the order of operations is a
bit different depending on wether there is DMA or not. In DMA mode you
first prepare the buffer, then run the command. In non-DMA mode you
first send the command, then read the data into the buffer. We need an
API at the mmc_bus level that doesn't care about that low-level detail.
There are other things that the MMC bus should be doing however, such
as switching to different clock speeds depending on which card is
activated and how fast it can go.
At least the following should be done:
- The read method for mmc_bus and sdhci_pci should use a scatter-gather
structure as a parameter instead of a single buffer
- See if can be integrated into ExecuteCommand at sdhci level (it's
essentially a command with an additional data phase)

No read and write support for now. But we implement getting SD card
capacity. SDHC is not supported yet (it uses a different layout for the
CSD register which will be rejected by this version of the code)

is used, it's size will be 1 byte.
