Give the previously unnamed enum a typedef name. Use the packed
attribute so that we do not affect the layout of the float_status
struct. Use it in the prototypes of relevant functions.
Adjust switch statements as necessary to avoid compiler warnings.

The "access" arguments clash with a macro under Windows with MinGW:
CC m68k-softmmu/target/m68k/fpu_helper.o
target/m68k/fpu_helper.c: In function 'fmovem_predec':
target/m68k/fpu_helper.c:405:56: error: macro "access" passed 4 arguments,
but takes just 2
size = access(env, addr, &env->fregs[i], ra);
So this renames them access_fn.
Tested with:
./configure --target-list=m68k-softmmu
make -j8

It's either "GNU *Library* General Public License version 2" or
"GNU Lesser General Public License version *2.1*", but there was
no "version 2.0" of the "Lesser" license. So assume that version
2.1 is meant here.
Also some files mention the GPL instead of the LGPL after declaring
that the files are licensed under the LGPL, so change these spots to
use LGPL, too.

As cpu.h is another typically widely included file which doesn't need
full access to the softfloat API we can remove the includes from here
as well. Where they do need types it's typically for float_status and
the rounding modes so we move that to softfloat-types.h as well.
As a result of not having softfloat in every cpu.h call we now need to
add it to various helpers that do need the full softfloat.h
definitions.

real constants:

Convert the array to make_floatx80_init() to fix it.
Replace floatx80_pi-like constants with make_floatx80_init() as they are
defined as make_floatx80().
This fixes build on SmartOS (Joyent).
