compiler: use fully-qualified names for tracking functions
...
Function name now consists of 3 parts:
1) full package path
2) method receiver type (if any)
3) function name itself .

compiler: process interop together with package
...
Closes #913 .
Provide package info in the funcScope to check if function is defined
insided an interop package. As a good side-effect bytecode for builtins from `util`
is no longer emitted.
Related #941 .

vm: implement slot-related opcodes
...
1. Slot is a new mechanism for storing variables during execution
which is more convenient than alt.stack. This commit implements
support for slot opcodes in both vm and compiler.
2. Remove old alt.stack opcodes.
3. Do not process globals at the start of every function, but instead
load them single time at main.

It really deserves it, I think. Especially given that it doesn't have any
direct usage of `vm` package now.
