Jake Hillion 7de35863f5 tbv2: fix Thrift isset lookups with padding 
Thrift isset was failing with a SEGV if the struct contained padding. This is
because we indexed the `isset_indexes` data structure using our field index
rather than the index of the field in Thrift. This then gave a rubbish index
for any exceeding which happens if we have added padding in the middle of the
struct, and this index was looked up in the bitset which can cause a SEGV.

Track a new index `thriftFieldIdx` which is only incremented if we've looked up
a Thrift index.

Namespaced the generated Thrift structs while I was there. This isn't necessary
anymore but cleans things up.

Test plan:
- Added a test case with lots of padding. These don't run in the CI but it
  passes locally.
- `FILTER='OilIntegration.*' make test` - no failures
- `FILTER='OidIntegration.*' make test` - no new failures

Object Introspection is a memory profiling technology for C++ objects. It provides the ability to dynamically instrument applications to capture the precise memory occupancy of entire object hierarchies including all containers and dynamic allocations. All this with no code modification or recompilation!

For more information on the technology and how to get started applying it to your applications please check out the Object Introspection website.
