fernantho 10a2f0687b SSZ-QL: calculate generalized indices for elements (#15873)
* added tests for calculating generalized indices

* added first version of GI calculation walking the specified path with no recursion. Extended test coverage for bitlist and bitvectors.
vectors need more testing

* refactored code. Detached PathElement processing, currently done at the beginning. Swap to regex to gain flexibility.

* added an updateRoot function with the GI formula. more refactoring

* added changelog

* replaced TODO tag

* udpated some comments

* simplified code - removed duplicated code in processingLengthField function

* run gazelle

* merging all input path processing into path.go

* reviewed Jun's feedback

* removed unnecessary idx pointer var + fixed error with length data type (uint64 instead of uint8)

* refactored path.go after merging path elements from generalized_indices.go

* re-computed GIs for tests as VariableTestContainer added a new field.

* added minor comment - rawPath MUST be snake case

removed extractFieldName func.

* fixed vector GI calculation - updated tests GIs

* removed updateRoot function in favor of inline code

* path input data enforced to be snake case

* added sanity checks for accessing outbound element indices - checked against vector.length/list.limit

* fixed issues triggered after merging develop

* Removed redundant comment

* removed unreachable condition as `strings.Split` always return a slice with length >= 1

If s does not contain sep and sep is not empty, Split returns a slice of
length 1 whose only element is s.

* added tests to cover edge cases + cleaned code (toLower is no longer needed in extractFieldName function

* added Jun's feedback + more testing

* postponed snake case conversion to do it on a per-element-basis. Added more testing focused mainly in snake case conversion

* addressed several Jun's comments.

* added sanity check to prevent length of a multi-dimensional array. added more tests with extended paths

* Update encoding/ssz/query/generalized_index.go

* placed constant bitsPerChunk in the right place. Exported BitsPerChunk and BytesPerChunk and updated code that use them

* added helpers for computing GI of each data type

* changed %q in favor of %s

* Update encoding/ssz/query/path.go

* removed the least restrictive condition isBasicType

* replaced length of containerInfo.order for containerInfo.fields for clarity

* removed outdated comment

* removed toSnakeCase conversion.

* moved isBasicType func to its natural place, SSZType

* cosmetic refactor

- renamed itemLengthFromInfo to itemLength (same name is in spec).
- arranged all SSZ helpers.

* cleaned tests

* renamed "root" to "index"

* removed unnecessary check for negative integers. Replaced %q for %s.

* refactored regex variables and prevented re-assignation

* added length regex explanation

* added more testing for stressing regex for path processing

* renamed currentIndex to parentIndex for clarity and documented the returns from calculate<Type>GeneralizedIndex functions

* Update encoding/ssz/query/generalized_index.go

* fixed never asserted error. Updated error message
