MEDIUM: tree-wide: replace most DECLARE_POOL with DECLARE_TYPED_POOL

This will make the pools size and alignment automatically inherit
the type declaration. It was done like this:

   sed -i -e 's:DECLARE_POOL(\([^,]*,[^,]*,\s*\)sizeof(\([^)]*\))):DECLARE_TYPED_POOL(\1\2):g' $(git grep -lw DECLARE_POOL src addons)
   sed -i -e 's:DECLARE_STATIC_POOL(\([^,]*,[^,]*,\s*\)sizeof(\([^)]*\))):DECLARE_STATIC_TYPED_POOL(\1\2):g' $(git grep -lw DECLARE_STATIC_POOL src addons)

81 replacements were made. The only remaining ones are those which set
their own size without depending on a structure. The few ones with an
extra size were manually handled.

It also means that the requested alignments are now checked against the
type's. Given that none is specified for now, no issue is reported.

It was verified with "show pools detailed" that the definitions are
exactly the same, and that the binaries are similar.
