Couple use of initialization priorities to no NO_OS_DEPENDENCE
Add comments explaining what integer does, how it does it, and why we want to inprove on the Singleton pattern as a resource manager.
Update documentation.
This effectively decouples Integer and Public Key from the rest of the library. The change means a compile time define is used rather than a runtime pointer. It avoids the race with Issue 389.
The Public Key algorithms will fail if you use them. For example, running the self tests with CRYPTOPP_NO_ASSIGN_TO_INTEGER in effect results in "CryptoPP::Exception caught: NameValuePairs: type mismatch for 'EquivalentTo', stored 'i', trying to retrieve 'N8CryptoPP7IntegerE'". The exception is expected, and the same happend when g_pAssignIntToInteger was present.
Wrap DetectArmFeatures and DetectX86Features in InitializeCpu class
Use init_priority for InitializeCpu
Remove HAVE_GCC_CONSTRUCTOR1 and HAVE_GCC_CONSTRUCTOR0
Use init_seg(<name>) on Windows and explicitly insert at XCU segment
Simplify logic for HAVE_GAS
Remove special recipies for MACPORTS_GCC_COMPILER
Move C++ static initializers into anonymous namespace when possible
Add default NullNameValuePairs ctor for Clang
When MSVC init_seg or GCC init_priority is available, we don't need to use the Singleton. We only need to create a file scope class variable and place it in the segment for MSVC or provide the attribute for GCC.
An additional upside is we cleared all the memory leaks that used to be reported by MSVC for debug builds.
This avoids a potential problem when OR'ing with 0 that results in a WordCount() of 1. Integer's minimum reg[] size is 2 due to RoundupSize(), and there could be implicit assumptions for the minimum that did not surface under testing

This may not fix the issue. Drilling into the issue from the web-based dashboard, Coverity is targeting:
1. noescape: CryptoPP::Integer::operator =(CryptoPP::Integer const &) does not free or save its parameter t.
3049 Integer& Integer::operator=(const Integer& t)
3050 {
3051 if (this != &t)
3052 {
3053 if (reg.size() != t.reg.size() || t.reg[t.reg.size()/2] == 0)
3054 reg.New(RoundupSize(t.WordCount()));
3055 CopyWords(reg, t.reg, reg.size());
3056 sign = t.sign;
3057 }
3058 return *this;
3059 }
trap.h and CRYPTOPP_ASSERT has existed for over a year in Master. We deferred on the cut-over waiting for a minor version bump (5.7). We have to use it now due to CVE-2016-7420
