mrambacher 826295a5e9 Change autovector to have a reserved size in LITE mode (#6868) 
Summary:
Previously in LITE mode, an autovector did not have a reserved size. When
elements were added to the vector, the underlying array could be reallocated.

There was a set of code that never expands the autovector and was doing &autovector::back().  When the vector is resized, the old addresses may become invalid, causing a later exception to be thrown.

By reserving space in the autovector up front, this problem is eliminated for those uses where the vector will never exceed the initial size.

the resize happens, these pointers become invalid, leading to SEGV or other exceptions.

This change allows the autovector to be fully populated before we take the address of any of its elements, thereby elminating the potential for a resize.

There is comparable code to this change in Version::MultiGet for dealing with the context objects.
