1a02abf7b2 feat(util/script_state): add a lua hook function that checks for the interrupt flag 
This is a very convenient feature for interrupting non-terminating user scripts.
Before this commit, the user had to manually invoke check_interrupt() in potentially expensive loops. Now, this is not needed anymore.

Remark: we still have to check whether this trick works with LuaJIT or not.

f80106a895 chore(*): use 'explicit operator bool' everywhere. 
operator bool() may produce unwanted conversions.
For example, we had the following bug in the code base.

...
   object const & obj = find_object(const_name(n));
   if (obj && obj.is_builtin() && obj.get_name() == n)
...

obj.get_name() has type lean::name
n              has type lean::expr

Both have 'operator bool()', then the compiler uses the operator to
convert them to Boolean, and then compare the result.
Of course, this is not our intention.

After this commit, the compiler correctly signs the error.
The correct code is

...
   object const & obj = find_object(const_name(n));
   if (obj && obj.is_builtin() && obj.get_name() == const_name(n))
...

83aaf64318 fix(library/tactic): memory leaks 
Proof/Cex builders and tactics implemented in Lua had a "strong reference" to script_state. If they are stored in the Lua state, then we get a cyclic reference.
That is, script_state points to these objects, and they point back to script_state.

To avoid this memory leak, this commit defines a weak reference for script_state objects. The Proof/Cex builders and tactics now store a weak reference to the Lua state.

ce674d2d43 feat(library/tactic): execute Lua tactics using coroutines 
This is very important when several Lua tactics are implemented in the
same Lua State object.  In this case, even if we use the par
combinator, a Lua tactic will block the other Lua tactics running in
the same Lua State object.

With this commit, a Lua tactic can use yield to allow other tactics
in the same State object to execute.

d87ad9eb7e refactor(util/lua): propagate C++ Lean exceptions in Lua 
The following call sequence is possible:
C++ -> Lua -> C++ -> Lua -> C++

The first block of C++ is the Lean main function.
The main function invokes the Lua interpreter.
The Lua interpreter invokes a C++ Lean API.
Then the Lean API invokes a callback implemented in Lua.
The Lua callback invokes another Lean API.
Now, suppose the Lean API throws an exception.
We want the C++ exception to propagate over the mixed C++/Lua call stack.
We use the clone/rethrow exception idiom to achieve this goal.

Before this commit, the C++ exceptions were converted into strings
using the method what(), and then they were propagated over the Lua
stack using lua_error. A lua_error was then converted into a lua_exception when going back to C++.
This solution was very unsatisfactory, since all C++ exceptions were being converted into a lua_exception, and consequently the structure of the exception was being lost.

956f203a55 refactor(bindings/lua): move Lua bindings to the file associated with them 
The directory bindings/lua was getting too big and had too many dependencies.
Moreover, it was getting too painful to edit/maintain two different places.
Now, the bindings for module X are in the directory that defines X.
For example, the bindings for util/name.cpp are located at util/name.cpp.

The only exception is the kernel. We do not want to inflate the kernel
with Lua bindings. The bindings for the kernel classes are located
at bindings/kernel_bindings.

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.

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.
