Fixed bit-rotted `show_area's count-based MANIFEST_CLOSURE botchery,

Fixed bit-rotted `show_area's count-based MANIFEST_CLOSURE botchery,
broken `break'-embedding macrology (got whacked in ver.9.46) and such:

0. Include "storage.c" for `Type_Names' and "gctype.c" goodies.
1. Fixed dropped high-order bit on addr & datum hex print (6-bit type).
2. Explicit (not embedded) `break's after (NON_)POINTER() macro calls.
3. Made `TC_NULL' & `TC_TRUE' print less misleadingly when not #T/#F.
4. Patched MANIFEST_CLOSUREs, STACK_ENVIRONMENTs & LINKAGE_SECTIONs as:
5. Area-based display a la "uxtrap.c" using GC macros is much cleaner
   (despite the odd redefinition of `MANIFEST_CLOSURE_END()' ver.1.31).
6. Fixed bogus `Next' update for `Const_Count' non-zero (fix end addr).
