* [verifier] limit the number of back edges

* [verifier] fix incorrect error code for per-module back edge limit check

* copyloc-pop test (starcoinorg#54)

* [gas] allow natives to read the gas balance

* [bytecode-verifier] Add metering logic and apply to absint based analysis (starcoinorg#58)

This adds a simple meter to the bytecode verifier which counts the number of abstract operations performed and can enforce a limit. The meter is for now only connected to locals and reference analysis, but plumped to all phases of the verifier so they can easily make use of it.

A set of test cases have been added which exercise the new meter for a number of known pathological cases.

PR history:

- Add metering in type safety, to capture cost of very large types. This reduces timing of large_type_test to 1/4
- Adjusting max metering units upwards and adding a new sample which needs it
- Addressing reviewer comments
- Add links to security advisories, and verify that all are covered.
- Switching metering granularity from function to module.
- Adding non-linear growing penalty to using input refs x output refs relations (bicycles), for dealing better with `test_bicliques`. Adding printing size in benchmarks.

* [bytecode verifer] Adjust metering to decrease runtime of some tests. (starcoinorg#62)

Specifically the test below now runs in 1/2 of the time. This adjustment appeard useful because the overall time allocation had to be increased to 8000 million units in production. Adjusted this as the default here too.

```
--> test_merge_state: verification time: 59.414ms, result: CONSTRAINT_NOT_SATISFIED, size: 63kb
```

Also adjusts the default to what aptos uses now in production.

* [bytecode verifier] Meter type instantiations (starcoinorg#64)

Instead of just metering size of types on the operand stack, also meter size of type instantiations in calls and other places. This e.g. capture the size of types in calls like `f<T>()`, where the type does not appear on the operand stack.
