db027ad9c5 vm: zero GAS means no GAS, use fee data to properly limit execution 
We were accepting transactions with zero system fee, but we shouldn't do
that. Also, transaction's verification execution has to be limited by network
fee.

1bb26dcdc1 vm: fix INITSSLOT, it's context-wide, not VM-wide 
It's tied to the current contract, not to VM.

73b630db9b *: switch from fixed8 to int64 
Follow C# implementation, we have to marshall JSON Fixed8 fields without
taking into account decimals.

a77357227a vm: fix caller's script hash returned from VM 
Regular CALLs don't update it, only Contract.Call does. Fixes the following
mismatch on preview2 testnet:

file BlockStorage_100000/dump-block-49000.json: block 48644, changes number mismatch: 6 vs 4

a7d4fff897 vm: make (*VM).GasLimit public 
VM is inherently single-threaded and replacing setter/getter methods
with public field simplifies code a bit.

7256efd1ed vm: implement (*VM).AddGas 
Calculating interop prices can be tricky. It is more convenitent to burn
gas inside interops where necessary parameters are popped.

0cb6dc47e4 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.
