A fix for Bug#928222 Memory leak when running a long
stored procedure.

An original patch was prepared done by Alexey Demakov.

When running a long stored procedure, the server could
allocate a lot of memory in the fiber garbage collected
pool, when performing requests in a loop.

To fix the bug, garbage collect memory after every call to
rw_callback() from stored procedures module.

Add ptruncate() method to palloc, which rolls back
used memory to a saved position and use it in box_lua.m.

Since VALGRIND MEMPOOL API doesn't support ptruncate(),
don't use it, instead consistently use
VALGRIND_MAKE_MEM_DEFINED/VALGRIND_MAKE_MEM_UNDEFINED.

No test case since the problem is detected by a longevity
test, not a functional test.
