Gareth Rees 981a266642 New public functions mps_pool_total_size and mps_pool_free_size.
Old (undocumented) functions mps_{mv,mvff,mvt}_size and mps_{mv,mvff,mvt}_free_size are now macros for the new public functions.
New pool methods PoolTotalSize and PoolFreeSize, with implementations for public pool classes except SNC.
Coverage of the new functions in apss and mpmss for the manual pool classes, and in finaltest for the automatic pool classes.

* size_t minimum_size,
* size_t mean_size,

* minimum_, mean_, and maximum_size are the mimimum, mean, and
* maximum (typical) size of objects expected to be allocated in the
* pool. reserve_depth is a measure of the expected hysteresis of the
* object population. fragmentation_limit is a percentage (between 0
* and 100): if the free space managed by the pool exceeds the
* specified percentage, the pool will resort to a "first fit"
* allocation policy.
