[Threads-devel] v2/shared_mutex bitmask refactoring

Subject: [Threads-devel] v2/shared_mutex bitmask refactoring

The "bitmask" manipulation in v2/shared_mutex and v2/upgrade_mutex makes
the code difficult to understand. The attached patch attempts to replace
the bitmasks with more manageable "bitfields". This leads to shorter and
more readable code with equivalent performance.

All "thread" tests still pass on my Win7/x64 computer with
v2/shared_mutex.hpp manually included from thread/shared_mutex.hpp.

If the patch is appreciated, then I can also send a similar patch for
v2/upgrade_mutex.

Regards,
Fredrik
