THRIFT-922. cpp: Fix C++ compilation when using list<bool>

The STL specializes vector<bool> to store the values as individual bits, rather
than bools.  Therefore, when using a Thrift list<bool>, readBool() gets invoked
not with a bool&, but with a std::vector<bool>::reference.

TProtocol does provide a readBool(std::vector<bool>::reference) implementation.
However, almost all TProtocol subclasses defined only readBool(bool&), which
hides the other overloaded versions of readBool().  As a result, the code
worked only when accessing TProtocol objects via a "TProtocol*", and not
directly via the subclass type.  When using C++ templates, protocol objects do
get invoked via pointers to the subclass type, causing compile failures when
std::vector<bool> is used.

This change updates the various TProtocol implementations to also provide
readBool(std::vector<bool>::reference).
