debug: enable bget memory leak detection

This patch enables memory leak detection in bget_malloc.c.
This is very helpful to find memory leakage issue in teecore
or user TA. To enable it in teecore, build optee_os with
`CFG_TEE_CORE_MALLOC_DEBUG=y`. For user TA, build optee_os
with `CFG_TEE_TA_MALLOC_DEBUG=y`.

Then, add the following statement at some point of your
code that might frequently been triggered:

mdbg_check(1);

It will dump allocated memory blocks and the holders of
them. If you find a memory block appears multiple times
after the system runs a period of time, it is very likely
the source of memory leakage.

Here is an example output:

ERR TEE-CORE:mdbg_check:720: Orphaned buffer: 0 bytes core/tee/tee_svc_storage.c:260

You can see the buffer hold by strdup.c:34 appears 4 times,
so it's very likely to be the source of memory leakage.

Move bget to libutils replacing dlmalloc

* Moves bget to libutils replacing dlmalloc as kernel memory allocator
* Restores the code formatting of bget.{c,h} to the original state as
parts of the current code was unreadable
* Adds malloc_add_pool() to make use of previously unused memory
* Moves call to malloc_init() into platform specific code
* Restores MDBG into working condition
* Adds memalign function to bget.
