BDE 3.99.3 Highlights

Move constructibility changes for BindWrapper

Moving a BindWrapper object (as created by BindUtil::bindS) would previously result in an unnecessary allocation and deallocation. This change ensures BindWrapper is bitwise move constructible and therefore the unnecessary allocation does not take place. A basic benchmark showed a performance improvement of up to 15% . As part of this change a small correction was also made to bsl::shared_ptr because previously, in C++03 only, the is_nothrow_move_constructible trait would incorrectly return false.

Continued Addition of C++17 Type Aliases

This release adds bsl:: aliases for the C++17 features in bsl_algoritm.h, bsl_chrono.h, and bsl_numeric.h. This is part of the general effort to simplify the use of bsl:: names, and in general better support C++17.

Fixed requests: 3.99.3
