15f0899efb refactor(*): replace LEAN_THREAD_LOCAL with MK_THREAD_LOCAL_GET, the new macro uses the Boost thread_local_ptr instead of 'thread_local' directive
Motivation: clang++ on OSX does not support 'thread_local'.

e7ae749221 feat(boost): implement multi-threading support using Boost
To use Boost instead of the standard library, we must use the cmake option
    -D BOOST=ON

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.

a776c8b158 feat(util/interrupt): add sleep_for, and simplify request_interrupt
The Lean sleep_for checks the interrupt flag from time to time.

c4c548dc5d feat(*): simplify interrupt propagation
Instead of having m_interrupted flags in several components. We use a thread_local global variable.
The new approach is much simpler to get right since there is no risk of "forgetting" to propagate
the set_interrupt method to sub-components.

The plan is to support set_interrupt methods and m_interrupted flags only in tactic objects.
We need to support them in tactics and tacticals because we want to implement combinators/tacticals such as (try_for T M) that fails if tactic T does not finish in M ms.
For example, consider the tactic:

    try-for (T1 ORELSE T2) 5

It tries the tactic (T1 ORELSE T2) for 5ms.
Thus, if T1 does not finish after 5ms an interrupt request is sent, and T1 is interrupted.
Now, if you do not have a m_interrupted flag marking each tactic, the ORELSE combinator will try T2.
The set_interrupt method for ORELSE tactical should turn on the m_interrupted flag.
