[v3] __native_type typedefs, condition_variable, typesize

[Benjamin Kosnik]

Adds consistent private __native_type typedefs for
mutex/condition_variable, makes the current ones private.

For std::condition_variable, there is an extra mutex data object that is
superfluous, as it is used only in notify_one/notify_all member
functions, which call pthread_cond_signal/broadcast, which do not need
to be locked. So, removed.

Adds some type/native_type compares to the testsuite.
