p needs to point to LWIP_MEM_ALIGN(memp_pools[i]->base) otherwise it will cause
assertion in overflow checking.

When memp_free_pool was split out from memp_free (c838e1ed5b),
the check for freeing the null pointer was lost.
This resulted in the null value being put back in the list of free
objects, causing all subsequent allocations of that type to fail.
MEMP_SANITY_REGION_BEFORE and MEMP_SANITY_REGION_AFTER can be overridden in
lwipopts.h, if one of it is set to 0 we got build error due to unused variable.
Fix unused variable build error when MEMP_OVERFLOW_CHECK >= 1 &&
(MEMP_SANITY_REGION_BEFORE == 0 || MEMP_SANITY_REGION_AFTER == 0).

There is only one caller using memp_overflow_init(), and at that context
calling memp_overflow_init_element() actually simplifes the code.
Thus remove memp_overflow_init() function.

Use LWIP_MEM_ALIGN() in memp_overflow_init() to get alignment address for memp.
This fixes assertion in memp_overflow_check_element_overflow when
MEMP_OVERFLOW_CHECK is set.

Fix below build error.

- support memp stats when MEMP_MEM_MALLOC==1 (bug #48442);
- hide MEMP_MEM_MALLOC in memp.c instead of messing up the header file;
- make MEMP_OVERFLOW_CHECK work when MEMP_MEM_MALLOC==1
We don't really care the order of overflow/underflow checking because if
any checking fails we got assertion.

Current code already checks memp_overflow_check_all() in memp_free() if
MEMP_OVERFLOW_CHECK >= 2. So in memp_free_pool(), it should use
MEMP_OVERFLOW_CHECK == 1 instead.

The h will point to NULL if h->next->next is NULL anyway.
So remove the unnecessary NULL test for h->next->next in each iteration.
