erts: Add pooled_list and traitor_list
erts: Fix bug causing mbc removed from cpool to be used at pool entrance

Clear both IN_POOL and BUSY flags when empty carrier is removed
is removed from pool to be destroyed.

we must clear IN_POOL to avoid using it as cpool_entrance in cpool_fetch().

erts: Fix bug causing mbc to be deleted from cpool before it was inserted

Set IN_POOL flag _after_ mbc has been actually inserted.

Earlier it did not matter if IN_POOL was set early as it was not possible
to find a carrier before is was fully inserted. Now when searching
pooled_list and traitor_list we must make sure a found carrier has been
fully inserted into cpool before removing it.

OTP-8188 introduced a fix for handling last expressions in
expressions like case, try and friends. However the fix did

have no clauses (only an after clause), leading to a function
clause error when cover compiling code with such expressions.

Fix signedness bug

The regression was introduced by making byte type signed.

Bitwise OR (|) applied to signed char (byte) and any longer type reqires the former to expand to the same size.
When the char is negative it is expanded with sign bit filling the extra bytes causing the unexpected result.
