bus: Make struct device a pointer ...

struct bus_type contains an embedded struct device_d which is quite
a big structure. Dynamically allocate this instead to save the space
in the binary.

drivers/base: fix corrupt device tree ...

dev_add_child is a very unsafe function. If called multiple times
it allows setting the same device to different parents thus corrupting
the siblings list. This happens regularly since:

|    bus: add bus device
|
|    automatically add it as parent of any bus device if none already specified
|
|    we have now a nice output per bus

If for example a FATfs is mounted this nice output per bus often ends with:

This patch fixes this by adding a device to its parents children list in
register_device so that dev_add_child is no longer needed. This function
is removed from the tree. Now callers of register_device have to clearly
set the parent *before* registering a device.

The name "serial_ns16550" is not handy because the devices

"serial_ns165502" etc.

The names like "ns16550_serial0" and "ns16550_serial1" look
much better.

Also it is reasonable to make serial driver's names unification.
E.g. see the names for drivers in drivers/serial directory:
 "netx_serial",
 "mpc5xxx_serial",
 "altera_serial",
 "s3c_serial",
 "imx_serial",
 "pxa_serial",
 "blackfin_serial",
 "stm_serial",
 "pl010_serial",

fs: fix standard zero, full devices ...

The standard devices are currently broken since they have
the size ~0. As now files use loff_t as file size which is a signed
type the read implementation gets confused and now returns -1.

The current implementation also has the (somewhat theorical) problem
that we do not have real streaming devices, so /dev/zero went out
of zeroes after reading 4GB (or now LLONG_MAX).

This patch introduces a new cdev flag DEVFS_IS_CHARACTER_DEV and a new
file size flag FILE_SIZE_STREAM which makes it possible to create
real stream devices instead.
