General refactoring, using C++11

Browse Source 
* Remove broken RecycledObjectPool

* Fix beast::ServiceQueue using List instead of LockFreeStack

* Add class semaphore, fixes broken Semaphore

* Move crytpo module files to new beast directory

* Use c++11 replacements for boost and beast types:
  - std::atomic instead of beast::Atomic
  - std::function instead of boost::function, beast::function
  - std::unique_ptr instead of beast::ScopedPointer
  - std::shared_ptr instead of boost::shared_ptr

* Remove modules:
  - beast_db
  - beast_crypto
  - beast_extras

* Remove unnecessary classes:
  - AbstractFifo
  - AddConst
  - AtomicCounter
  - AtomicFlag
  - AtomicPointer
  - AtomicState
  - CopyConst
  - Expression
  - ForwardList
  - IfCond
  - Interval
  - IntrusiveArray
  - KeyvaDB
  - PointerToOther
  - PointerTraits
  - RemoveConst
  - RemoveConstVolatile
  - RemoveReference
  - RemoveVolatile
  - SharedObjectArray
  - SingleThreadedSharedObject
  - SophiaDB factory
  - SortedSet
  - WeakReference
  - beast::unique_ptr

/**
Encapsulates the logic required to implement a lock-free FIFO.
This class handles the logic needed when building a single-reader,
single-writer FIFO.
It doesn't actually hold any data itself, but your FIFO class can use one of
these to manage its position and status when reading or writing to it.
To use it, you can call prepareToWrite() to determine the position within
your own buffer that an incoming block of data should be stored, and
prepareToRead() to find out when the next outgoing block should be read from.
e.g.
@code
class MyFifo
{
public:
MyFifo() : abstractFifo (1024)
{
}
void addToFifo (const int* someData, int numItems)
{
int start1, size1, start2, size2;
abstractFifo.prepareToWrite (numItems, start1, size1, start2, size2);
if (size1 > 0)
copySomeData (myBuffer + start1, someData, size1);
if (size2 > 0)
copySomeData (myBuffer + start2, someData + size1, size2);
abstractFifo.finishedWrite (size1 + size2);
}
void readFromFifo (int* someData, int numItems)
{
int start1, size1, start2, size2;

Because the section of data that you want to add to the buffer may overlap the end

should copy your data into the first one, with any remaining data spilling over into
the second.
If the number of items you ask for is too large to fit within the buffer's free space, then
blockSize1 + blockSize2 may add up to a lower value than numToWrite. If this happens, you
may decide to keep waiting and re-trying the method until there's enough space available.
After calling this method, if you choose to write your data into the blocks returned, you
must call finishedWrite() to tell the FIFO how much data you actually added.
e.g.
@code
void addToFifo (const int* someData, int numItems)

prepareToWrite (numItems, start1, size1, start2, size2);

If the number of items you ask for is greater than the amount of data available, then
blockSize1 + blockSize2 may add up to a lower value than numWanted. If this happens, you
may decide to keep waiting and re-trying the method until there's enough data available.
After calling this method, if you choose to read the data, you must call finishedRead() to
tell the FIFO how much data you have consumed.
e.g.
@code
void readFromFifo (int* someData, int numItems)
{
int start1, size1, start2, size2;
prepareToRead (numSamples, start1, size1, start2, size2);
if (size1 > 0)
copySomeData (someData, myBuffer + start1, size1);
if (size2 > 0)
copySomeData (someData + size1, myBuffer + start2, size2);
finishedRead (size1 + size2);
}
@endcode
@param numWanted indicates how many items you'd like to add to the buffer
@param startIndex1 on exit, this will contain the start index in your buffer at which your data should be written
@param blockSize1 on exit, this indicates how many items can be written to the block starting at startIndex1
@param startIndex2 on exit, this will contain the start index in your buffer at which any data that didn't fit into
the first block should be written
@param blockSize2 on exit, this indicates how many items can be written to the block starting at startIndex2
@see finishedRead
*/
void prepareToRead (int numWanted, int& startIndex1, int& blockSize1, int& startIndex2, int& blockSize2) const noexcept;
/** Called after reading from the FIFO, to indicate that this many items have now been consumed.

Holds a set of unique primitive objects, such as ints or doubles.
A set can only hold one item with a given value, so if for example it's a
set of integers, attempting to add the same integer twice will do nothing
the second time.
Internally, the list of items is kept sorted (which means that whatever
kind of primitive type is used must support the ==, <, >, <= and >= operators
to determine the order), and searching the set for known values is very fast
because it uses a binary-chop method.

this master pointer in its destructor.

@code

// threads overlap while creating the first WeakReference to it.
}

// This will zero all the references - you need to call this in your destructor.

// You need to embed a variable of this type, with the name "masterReference" inside your object. If the
// variable is not public, you should make your class a friend of WeakReference<MyObject> so that the
// WeakReference class can access it.
