3be166e3ae go.mod, go.sum: Update goleveldb 
Goleveldb recently had a PR in where memory allocation was reduced
drastically (github.com/syndtr/goleveldb/pull/367).  Update goleveldb
to use that PR.

txscript: Make op callbacks take opcode and data. 
This converts the callback function defined on the internal opcode
struct to accept the opcode and data slice instead of a parsed opcode as
the final step towards removing the parsed opcode struct and associated
supporting code altogether.

It also updates all of the callbacks and tests accordingly and finally
removes the now unused parsedOpcode struct.

The final results for the raw script analysis and tokenizer
optimizations are as follows:

txscript: Rename removeOpcodeByDataRaw func. 
This renames the removeOpcodeByDataRaw to removeOpcodeByData now that
the old version has been removed.

txscript: Refactor engine to use raw scripts. 
This refactors the script engine to store and step through raw scripts
by making using of the new zero-allocation script tokenizer as opposed
to the less efficient method of storing and stepping through parsed
opcodes.  It also improves several aspects while refactoring such as
optimizing the disassembly trace, showing all scripts in the trace in
the case of execution failure, and providing additional comments
describing the purpose of each field in the engine.

It should be noted that this is a step towards removing the parsed
opcode struct and associated supporting code altogether, however, in
order to ease the review process, this retains the struct and all
function signatures for opcode execution which make use of an individual
parsed opcode.  Those will be updated in future commits.

The following is an overview of the changes:

- Modify internal engine scripts slice to use raw scripts instead of
  parsed opcodes
- Introduce a tokenizer to the engine to track the current script
- Remove no longer needed script offset parameter from the engine since
  that is tracked by the tokenizer
- Add an opcode index counter for disassembly purposes to the engine
- Update check for valid program counter to only consider the script
  index
  - Update tests for bad program counter accordingly
- Rework the NewEngine function
  - Store the raw scripts
  - Setup the initial tokenizer
  - Explicitly check against version 0 instead of DefaultScriptVersion
    which would break consensus if changed
  - Check the scripts parse according to version 0 semantics to retain
    current consensus rules
  - Improve comments throughout
- Rework the Step function
  - Use the tokenizer and raw scripts
  - Create a parsed opcode on the fly for now to retain existing
    opcode execution function signatures
  - Improve comments throughout
- Update the Execute function
  - Explicitly check against version 0 instead of DefaultScriptVersion
    which would break consensus if changed
  - Improve the disassembly tracing in the case of error
- Update the CheckErrorCondition function
  - Modify clean stack error message to make sense in all cases
  - Improve the comments
- Update the DisasmPC and DisasmScript functions on the engine
  - Use the tokenizer
  - Optimize construction via the use of strings.Builder
- Modify the subScript function to return the raw script bytes since the
  parsed opcodes are no longer stored
- Update the various signature checking opcodes to use the raw opcode
  data removal and signature hash calculation functions since the
  subscript is now a raw script
  - opcodeCheckSig
  - opcodeCheckMultiSig
  - opcodeCheckSigAlt
