57f14280a7 Fix use-after-free on bytecode load/execution. 
lsig->bc was referring to the bytecode directly (via a pointer),
but the bytecode struct changes place in memory (it is realloced on each .cbc
load). So use an index instead of the direct pointer.

c1aff5ec76 fix loading from .cvd. 
Chomp first line too, and look for \0 instead of \n.

f6e8bb802a fix segfault on failed cbc load. 
The bytecode struct might be only partially initialized. Account for that.

f6798708fd Fix some pointer dereferences, and sizeof. 
There were some variables initialized with values from dereferenced pointers,
and the null check after the init.
Also sizeof must be applied to pointed to element.
