MINOR: pools: permit to optionally specify extra size and alignment

Browse Source 
The common macros REGISTER_TYPED_POOL(), DECLARE_TYPED_POOL() and
DECLARE_STATIC_TYPED_POOL() will now take two optional arguments,
one being the extra size to be added to the structure, and a second
one being the desired alignment to enforce. This will permit to
specify alignments larger than the default ones promised to the
compiler.
