malloc_test: new module for testing/debugging memory problems

malloc_test is a new module for stressing the memory allocators and easily simulating out-of-memory conditions or memory leaks.

Implemented RPCs: mt.mem_alloc size - allocates size bytes mt.mem_free [size] - frees at least size bytes. If size is missing frees everything allocated by any malloc_test test function. mt.mem_used - amount of currently allocated mem. by malloc_test. mt.mem_rnd_alloc min max total [unit] - allocates total <unit> bytes in chunks with the size randomly chosen between min and max. <unit> is optional and can be one of b-bytes, k - kb, m - mb, g -gb. mt.mem_test_start min max total min_int max_int total_time [unit] starts a malloc test that will take total_time to execute. Memory allocations will be performed at intervals randomly chosen between min_int and max_int (in ms). Each allocation will have a randomly chosen size between min and max <unit> bytes. After total <unit> bytes are allocated, everything is released/freed again and the allocations are restarted. The total_time is expressed in milliseconds. Several tests can be run in the same time. mt.mem_test_stop id - stops the test identified by id. mt.mem_test_destroy id - destroys the test identified by id (besides stopping it, it also frees all the data, including the statistics). mt.mem_test_destroy_all - destroys all the running or stopped tests. mt.mem_test_list [id] - Prints data about test id (running time, total allocations, errors a.s.o.). If id is missing, it will lists all the tests.

Script functions: mt_mem_alloc(size) - equivalent to the mt.mem_alloc RPC. mt_mem_free(size) - equivalent to the mt.mem_free RPC.
