linux-user/qemu.h is an awkward header, for two reasons:
(1) its name suggests it's a rather common generic header,
but it's actually specific to the usermode emulators
(2) it is a mix of:
* lots of things internal to the implementation of linux-user
* functions that a few files outside linux-user want
(mostly the user-access functions like lock_user,
get/put_user_*, etc, and also the TaskStruct definition)
This patchset tries to clean it up a bit by at least splitting
most of the "just internal to linux-user" parts out of qemu.h
and putting them in a handful of different .h files that are
then included by the linux-user files that need them.
I think the ideal would probably be to eventually junk
qemu.h entirely and have a few separate headers specifically
for the bits that non-linux-user code needs (eg a 'user-access.h'
for the get/put_user stuff), perhaps located somewhere that
means we don't need to put linux-user/ on the include path.
But that's awkward as it needs interaction with bsd-user too.
So this much cleanup seemed like a reasonable start...
