8f2fe273ea refactor(*): isolate std::thread dependency
This commit allows us to build Lean without the pthread dependency.
It is also useful if we want to implement multi-threading on top of Boost.

a2a5a77a44 fix(memory): increase memory counters by the actual size of reallocated memory
On OSX, we had a test failure on memory module. The problem was in
the realloc function (line 38):

    void * realloc(void * ptr, size_t sz) {
        size_t old_sz = malloc_size(ptr);
        g_global_memory.dec(old_sz);
        g_global_memory.inc(sz);
        g_thread_memory.dec(old_sz);
        g_thread_memory.inc(sz);
        void * r = realloc_core(ptr, sz);
        if (r || sz == 0)
            return r;
        else
            ...

The size of r could be bigger than sz. For instance,

    |ptr| = 40 but |r| = 48

In the current code, here we only increase counters by 40.
But later when we free it, we decrease them by 48, and this
caused the problem, underflow of an unsigned counter in
g_global_memory.
