- malloc(9) -> kmem(9)
- In ibm561_set_cmap(), allocating 3K on the stack is not polite; allocate
  a temporary buffer for the cmap data using kmem_alloc().

actually stop using the stack variable

avoid allocating almost 5k struct ibm561data on stack in ibm561_cninit();
it's too early for kmem_alloc(), so use static variable in BSS

Change old-style function defintions to C89 prototypes.

Approved by releng.

Don't pull in the whole uvm(9) API to access only PAGE_SIZE and
some other constants.  These are provided by sys/param.h now.

Commit is split, to avoid a "too many arguments" protocol error.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

eliminate uvm_useracc() in favor of checking the return value of
copyin() or copyout().

uvm_useracc() tells us whether the mapping permissions allow access to
the desired part of an address space, and many callers assume that
this is the same as knowing whether an attempt to access that part of
the address space will succeed.  however, access to user space can
fail for reasons other than insufficient permission, most notably that
paging in any non-resident data can fail due to i/o errors.  most of
the callers of uvm_useracc() make the above incorrect assumption.  the
rest are all misguided optimizations, which optimize for the case
where an operation will fail.  we'd rather optimize for operations
succeeding, in which case we should just attempt the access and handle
failures due to insufficient permissions the same way we handle i/o
errors.  since there appear to be no good uses of uvm_useracc(), we'll
just remove it.

add missing __KERNEL_RCSID()

Initial support for the IBM RGB561 RAMDAC.  This uses the same interface
as the Bt463 and Bt485 drivers.
