5a1b02bc10 Fix uninitialized use of scatter_unit_uX due to padding 
These non-packed structures are placed into a std::vector.  Later, they
contents of the vector are memcpy'd and the CRC of this space is taken.
Some compilers will zero the struct padding but GCC8.2 with -O2 at least
will not.  This means that the CRC is based on uninitialized memory.

Since it is expected that these bytes will be memcpy'd, zero in place once
they're in the std::vector.

Found by Valgrind.

Q.v. Issue #148

50ea83cb26 Move cpuid checks inline. 
During fat runtime function resolution there was a chance that the PLT
might not be initialised in time for us to call the cpuid check
functions. Moving them inline means there is no PLT to worry about.

Fixes #78

have to worry so much in future.
