clang-tidy fixes part-1

Details
- Use 'size_type' instead of 'int',
  propagate same 'size_type' into 'darray' etc.

- Use 'std::make_shared', 'std::make_unique'

- Use range-based for loops

- Remove redundant 'virtual', use 'override' in derived classes

- Use 'nullptr'

- Use default impl for dtor, ctor (incomplete)

- Use copy and std::move (incomplete)

- Explcitly catch std::bad_alloc in 'new' in 'noexcept' -> 'abort'
  - 'abort' was issued implicitly in noexcept methods

- L2CAPServer, L2CAPClient, NopGattServerHandler,
  DBGattServerHandler, FwdGattServerHandler
  - Use local close_impl(), usable in virtual destructor

- L2CAPClient::read, HCIComm::read
  - preset 'poll' result 'n', avoid garbage comparison

- BTAdapter::enableListening
  - loop through addMgmtEventCallback() result

- JNI code
  - explicit size_type is cast to jsize or jint w/o check
    - unchanged semantics
