Since the implementation is the same as for mulsi3, that code was moved to `riscv/int_mul_impl.inc` and is now reused by both `mulsi3.S` and `muldi3.S`.

So when there is a fork, the counters are resetted in the child process and they will be dumped at exit using the interprocess file locking. When there is an exec, the counters are written out and in case of failures they're resetted.

Let's ensure release 10 does not unexpectedly break builders with old SDKs and add proper minimal SDK checking in CMake for subsequent releases. This fix `#ifdef`s out interceptors for newer APIs. Note that the resulting TSan runtime is less complete: when these newer APIs are used TSan will report false positives.

This materialized in deadlocks in children. In order to properly support fork, we will lock the allocator pre-fork and unlock it post-fork in parent and child. This is done via a `pthread_atfork` call installing the necessary handlers. A couple of things suck here: this function allocates - so this has to be done post initialization as our init path is not reentrance, and it doesn't allow for an extra pointer - so we can't pass the allocator we are currently working with. In order to work around this, I added a post-init template parameter that gets executed once the allocator is initialized for the current thread. Its job for the C wrappers is to install the atfork handlers. I reorganized a bit the impacted area and added some tests, courtesy of cferris@ that were deadlocking prior to this fix.

Merge pool size >= 10 may be beneficial when the concurrency is large. Also fix a small problem about snprintf. It can cause the filename to be truncated after %m.

This change adds an explicit run of the comparator on all elements of the input array to catch any sanitizer bugs.
