Using a variable that is declared "const" for this tells the
compiler that it may read the value once and assume that it
does not change across function calls.
For target_page_size, this means we have only one assert per
function, and one read of the variable.
This reduces the size of qemu-system-aarch64 by 8k.

Such support is present almost everywhere, except for Xcode 9.
It is added in Xcode 10, but travis uses xcode9 by default,
so we should support it for a while yet.

The next patch will play a trick with "const" that will
confuse the compiler about the uses of target_page_bits
within exec.c. Moving everything to a new file prevents
this confusion.
No functional change so far.

qcow2_detect_metadata_preallocation() calls qcow2_get_refcount() which
requires s->lock to be taken to protect its accesses to the refcount
table and refcount blocks. However, nothing in this code path actually
took the lock. This could cause the same cache entry to be used by two
requests at the same time, for different tables at different offsets,
resulting in image corruption.
As it would be preferable to base the detection on consistent data (even
though it's just heuristics), let's take the lock not only around the
qcow2_get_refcount() calls, but around the whole function.
This patch takes the lock in qcow2_co_block_status() earlier and asserts
in qcow2_detect_metadata_preallocation() that we hold the lock.
