The ABI wrapper from r775 made the SHARED definitions obsolete. They're

not that readable anyway, so kill them and use standard definitions
instead.

Introduce EXPORT_SYMBOL for shared symbols. EXPORT_SYMBOL tells the
compiler to use the standard calling conventions for a given symbol and
not to optimize it away.
Benefits:
- We can later use gcc -combine -fwhole-program without problems.
- It's a correctness fix for some optimizations.
- We could check for duplicated exported functions at link time.
- We could check whether exported functions are linked into initram or
stage2 by accident.
- We could generate usage statistics and possibly optimize away unused
shared functions.
- Through the above points, significant side reductions of 10-40%

Build and boot tested on qemu.
Build tested on all targets.
