2a6eaeaa85 Move get_logical_cpus() from lavc/pthread to lavu/cpu.
It will be useful in lavfi, and could conceivably be useful to the user
applications as well.

ca6c3f2c53 lzo: fix overflow checking in copy_backptr()
The check `src > dst' in the form `&c->out[-back] > c->out' invokes
pointer overflow, which is undefined behavior in C.

Remove the check.  Also replace `&c->out[-back] < c->out_start' with
a safe form `c->out - c->out_start < back' to avoid overflow.

e460aa3282 atomic: Check for __sync_val_compare_and_swap instead of __sync_synchronize
Not all gcc configurations have an implementation of all the atomic
operations, and some gcc configurations have some atomic builtins
implemented but not all.

Thus check for the most essential function, whose presence should
indicate that all others are present as well, since it can be used
to implement all the other ones.
