accel/tcg: Use interval tree for TBs in user-only mode
Begin weaning user-only away from PageDesc.
Since, for user-only, all TB (and page) manipulation is done with
a single mutex, and there is no virtual/physical discontinuity to
split a TB across discontinuous pages, place all of the TBs into
a single IntervalTree. This makes it trivial to find all of the
TBs intersecting a range.
Retain the existing PageDesc + linked list implementation for
system mode. Move the portion of the implementation that overlaps
the new user-only code behind the common ifdef.

it doesn't take into account any heap memory that qemu
may allocate after startup.

Now that PageDesc is not used for user-only, and for system
it is only used for tb maintenance, move the implementation
into tb-main.c appropriately ifdefed.
We have not yet eliminated all references to PageDesc for
user-only, so retain a typedef to the structure without definition.

accel/tcg: Move remainder of page locking to tb-maint.c
The only thing that still touches PageDesc in translate-all.c
are some locking routines related to tb-maint.c which have not
yet been moved. Do so now.
Move some code up in tb-maint.c as well, to untangle the maze
of ifdefs, and allow a sensible final ordering.
Move some declarations from exec/translate-all.h to internal.h,
as they are only used within accel/tcg/.
