Merge #12366: http: Join worker threads before deleting work queue
11e0151 http: Remove numThreads and ThreadCounter (Wladimir J. van der Laan)
f946654 http: Remove WaitExit from WorkQueue (Wladimir J. van der Laan)
b1c2370 http: Join worker threads before deleting work queue (Wladimir J. van der Laan)

Pull request description:

  This prevents a potential race condition if control flow ends up in
  `ShutdownHTTPServer` before the thread gets to `queue->Run()`,
  deleting the work queue while workers are still going to use it.

  Meant to fix #12362.

Merge #10498: Use static_cast instead of C-style casts for non-fundamental types
9ad6746ccd Use static_cast instead of C-style casts for non-fundamental types (practicalswift)

Pull request description:

  A C-style cast is equivalent to try casting in the following order:

  1. `const_cast(...)`
  2. `static_cast(...)`
  3. `const_cast(static_cast(...))`
  4. `reinterpret_cast(...)`
  5. `const_cast(reinterpret_cast(...))`

  By using `static_cast<T>(...)` explicitly we avoid the possibility of an unintentional and dangerous `reinterpret_cast`. Furthermore `static_cast<T>(...)` allows for easier grepping of casts.

  For a more thorough discussion, see ["ES.49: If you must use a cast, use a named cast"](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#es49-if-you-must-use-a-cast-use-a-named-cast) in the C++ Core Guidelines (Stroustrup & Sutter).

11e01515fe http: Remove numThreads and ThreadCounter
The HTTP worker thread counter, as well as the RAII object that was used
to maintain it, is unused now, so can be removed.

6b3bb3d9ba Change LogAcceptCategory to use uint32_t rather than sets of strings.
This changes the logging categories to boolean flags instead of strings.

This simplifies the acceptance testing by avoiding accessing a scoped
 static thread local pointer to a thread local set of strings.  It
 eliminates the only use of boost::thread_specific_ptr outside of
 lockorder debugging.

This change allows log entries to be directed to multiple categories
 and makes it easy to change the logging flags at runtime (e.g. via
 an RPC, though that isn't done by this commit.)

It also eliminates the fDebug global.

Configuration of unknown logging categories now produces a warning.

d3773ca9ae httpserver: explicitly detach worker threads
When using std::thread in place of boost::thread, letting the threads destruct
results in a std::terminate. According to the docs, the same thing should be
be happening in later boost versions:
http://www.boost.org/doc/libs/1_55_0/doc/html/thread/thread_management.html#thread.thread_management.thread.destructor

I'm unsure why this hasn't blown up already, but explicitly detaching can't
hurt.
