Remove Cell Broadband Engine debugging support

Browse source 
This patch implements removal of Cell/B.E. support, including
- Support for the spu-*-* target
- Support for native stand-alone SPU debugging
- Support for integrated debugging of combined PPU/SPU applications
- Remote debugging (gdbserver) support for all the above.

The patch also removes the TARGET_OBJECT_SPU target object type,
as this is available only on Cell/B.E. targets, including
- Native Linux support
- Core file support (including core file generation)
- Remote target support, including removal of the qXfer:spu:read
  and qXfer:spu:write remote protocal packets and associated
  support in gdbserver.

it provides the following special commands:
@table @code
@item info spu event
@kindex info spu
Display SPU event facility status. Shows current event mask
and pending event status.
@item info spu signal
Display SPU signal notification facility status. Shows pending
signal-control word and signal notification mode of both signal
notification channels.
@item info spu mailbox
Display SPU mailbox facility status. Shows all pending entries,
in order of processing, in each of the SPU Write Outbound,
SPU Write Outbound Interrupt, and SPU Read Inbound mailboxes.
@item info spu dma
Display MFC DMA status. Shows all pending commands in the MFC
DMA queue. For each entry, opcode, tag, class IDs, effective

on the Cell Broadband Engine, it provides in addition the following
special commands:
@table @code
@item set spu stop-on-load @var{arg}
@kindex set spu
Set whether to stop for new SPE threads. When set to @code{on}, @value{GDBN}
will give control to the user when a new SPE thread enters its @code{main}
function. The default is @code{off}.
@item show spu stop-on-load
@kindex show spu
Show whether to stop for new SPE threads.
@item set spu auto-flush-cache @var{arg}
Set whether to automatically flush the software-managed cache. When set to
@code{on}, @value{GDBN} will automatically cause the SPE software-managed
cache to be flushed whenever SPE execution stops. This provides a consistent
view of PowerPC memory that is accessed via the cache. If an application
does not use the software-managed cache, this option has no effect.

/* Address conversions.
In a combined PPU/SPU debugging session, we have to consider multiple
address spaces: the PPU 32- or 64-bit address space, and the 32-bit
local store address space for each SPU context. As it is currently
not yet possible to use the program_space / address_space mechanism
to represent this, we encode all those addresses into one single
64-bit address for the whole process. For SPU programs using overlays,
this address space must also include separate ranges reserved for the
LMA of overlay sections.
The following combinations are supported for combined debugging:
PPU address (this relies on the fact that PPC 64-bit user space
addresses can never have the highest-most bit set):
+-+---------------------------------+
|0| ADDR [63] |
+-+---------------------------------+
SPU address for SPU context with id SPU (this assumes that SPU
IDs, which are file descriptors, are never larger than 2^30):
+-+-+--------------+----------------+
|1|0| SPU [30] | ADDR [32] |
+-+-+--------------+----------------+
SPU overlay section LMA for SPU context with id SPU:
+-+-+--------------+----------------+
|1|1| SPU [30] | ADDR [32] |
+-+-+--------------+----------------+
In SPU stand-alone debugging mode (using spu-linux-nat.c),
the following combinations are supported:
SPU address:
+-+-+--------------+----------------+
|0|0| 0 | ADDR [32] |
+-+-+--------------+----------------+
SPU overlay section LMA:
+-+-+--------------+----------------+
|0|1| 0 | ADDR [32] |
+-+-+--------------+----------------+
The following macros allow manipulation of addresses in the
above formats. */
