v6: memtank introduction
For analogy with mempool, named this structure memtank.
Same a s mempool it allows to alloc/free objects of fixed size
in a lightweight manner (not as lightweight as mempool,
but hopefully close enough).
The whole idea is that alloc/free is used at fast-path and don't
allocate/free more than *min_free* objects at one call.
So for majority of cases our fast-path alloc/free should be lightweight
(LIFO enqueue/dequeue operations).
Also user will need to call grow/shrink periodically
(ideally from the slow-path) to make sure there is enough
free objects in the tank.
Internally it is just a simple LIFO for up to *max_free* objects plus
a list of memory buffers (memchunk) from where these objects were
allocated.
v1 -> v2
- Added UT
- Fixed few bugs
v2 -> v3
- extend UT with more parameters
v3 -> v4
- add object alignement as parameter for memtank_create
- extend UT with more parameters
- added memtank dump routine
v4 -> v5
- fixed few bugs inside memtank lib
- extend UT with:
- new test case
- new command-line options: '-s <obj_size>', '-m <mem_func>'
v5 -> v6
- extend memtank dump to collect/display extra information
- make memtank dump routine MT safe
- add memtank sanity check function
- add proper comments for pubic API
