This reverts commit 86a8ef168dda766d2f25f15c15c4d3ecf21d0667.

* Fix memory errors when trim causes testcase growth

Modify trim_case_custom to avoid writing into in_buf because
some custom mutators can cause the testcase to grow rather than
shrink.

Instead of modifying in_buf directly, we write the update out
to the disk when trimming is complete, and then the caller is
responsible for refreshing the in-memory buffer from the file.

This is still a bit sketchy because it does need to modify q->len in
order to notify the upper layers that something changed, and it could
end up telling upper layer code that the q->len is *bigger* than
the buffer (q->testcase_buf) that contains it, which is asking
for trouble down the line somewhere...

* Fix an unlikely situation

Put back some `unlikely()` calls that were in
the e9d2f72382cab75832721d859c3e731da071435d commit that was
reverted.

96574854b3 libqasan/malloc: Additional pointer checks
Add checks to free() and malloc_usable_size() to
verify (sort of) that the pointers are actually
pointing at valid allocated memory before dereferencing
them and using the chunk_begin struct info.

This will catch use-after-free and wildly bad pointers
a little bit earlier.

87eb44abe4 Remove QEMU dependency checks
Most of these packages (bison, flex, pixman (in non-system mode)) are no
longer dependencies of QEMU and regardless, QEMU's build system is quite
capable of finding dependencies by itself and will error out
accordingly.  This prevents having to further change this code as QEMU's
dependencies inevitably change.
