d4de73cd2c heap: update the calculation of fl index max and use bitfield in control_t
The calculation of fl index max is changed to always be the smallest
number that includes the size of the registered memory.

The control_construct() function now checks for minimum size as the control structure
parameters are calculated.

There is no longer a minimum configuration for fl index max so the tlsf_config
enum is striped down to remove unecessary compile time values.

the tlsf_size() function will fail if no tlsf pointer is passed as parameter since there
is no way to calculate a default tlsf size anymore.

bitfields are now used in control_t when possible which reduces the size of the structure
from 56 bytes to 36 bytes.

6536e51a32 heap: Provide tlsf_check_hook() mechanism to check for memory corruption
Add a call to tlsf_check_hook() in tlsf_check() that calls
multi_heap_internal_check_block_poisoning() and check the memory
of every free blocks when heap poisoning is active.

09db8845c6 Heap: Fix a possible bug in the TLSF allocator
Fix a bug that could return a chunk of memory smaller than requested,
easily leading to a memory corruption, when the required memory alignment
passed to the allocator is 4.
