4ef9e50792 Really basic implementation of SDL2. 
Plus a crappy rectangle to prove that our vm screen code is working in
principle. (It will be removed shortly.)

8beb761535 Actually show a window. 
This is also the beginning outline of how we want to abstract graphics
away in erc.

b646bfc511 First stab at adding graphics. 
This involves using glfw. This first commit creates a window but doesn't
do anything with it; it also just hangs until you can escape out
somehow.

3f3210205f We missed the size multiplier for memset() 
In doing so, only a small portion of memory would have reliably been set
to zero; specifically, just the first element!

This change should resolve some intermittent test failures to guarantee
that all memory be zeroed.

079a35507c A number of updates in heavy dev phase 
1. Add an insert function (to insert a new disk).
2. Add a new shift function to coordinate sector position updates when
reading or writing.

256e0cf1d6 Don't write to the log stream if null

bb92162dba Zero, not NULL. 
Not that there's a practical difference, but we should be clear that
we're zeroing out memory because its contents are vm_8bit values, not
pointers.
