Christian Kaiser e102086f80 - fixed a bug in 64 bit ASM for MSVC

Tomasz Sowa d3a64b79ca added: support for wide characters (wchar_t)
wide characters are used when macro TTMATH_USE_WCHAR is defined
       this macro is defined automatically when there is macro UNICODE or _UNICODE defined
       some types have been changed
        char               -> tt_char
        std::string        -> tt_string
        std::ostringstream -> tt_ostringstream
        std::ostream       -> tt_ostream
        std::istream       -> tt_istream
       normally tt_char is equal char but when you are using wide characters then tt_char will be wchar_t (and so on)
       (all typedef's are in ttmathtypes.h)

Christian Kaiser be8913866a - 32 bit ASM code and ASSERTS did not work as the ASM code put its result in EAX, but the ASSERT afterwards did destroy the EAX's contents, of course.

Christian Kaiser fdc292e91a current chk version - too many changes on both sides for now ;-(

Tomasz Sowa eaa19dd46a added: uint UInt::Mul3(const UInt<value_size> & ss2)
void UInt::Mul3Big(const UInt<value_size> & ss2, UInt<value_size*2> & result)
         a new multiplication algorithm: Karatsuba multiplication,
         on a vector UInt<100> with all items different from zero this algorithm is faster
         about 3 times than Mul2Big(), and on a vector UInt<1000> with all items different from
         zero this algorithm is faster more than 5 times than Mul2Big()
         (measured on 32bit platform with GCC 4.3.3 with -O3 and -DTTMATH_RELEASE)
added:   uint MulFastest(const UInt<value_size> & ss2)
         void MulFastestBig(const UInt<value_size> & ss2, UInt<value_size*2> & result)
         those methods are trying to select the fastest multiplication algorithm
changed: uint Mul(const UInt<value_size> & ss2, uint algorithm = 100)
         void MulBig(const UInt<value_size> & ss2, UInt<value_size*2> & result, uint algorithm = 100)
         those methods by default use MulFastest() and MulFastestBig()
changed: changed a little Mul2Big() to cooperate with Mul3Big()
changed: names of methods in macros TTMATH_LOG()
added:   uint AddVector(const uint * ss1, const uint * ss2, uint ss1_size, uint ss2_size, uint * result)
         uint SubVector(const uint * ss1, const uint * ss2, uint ss1_size, uint ss2_size, uint * result)
         three forms: asm x86, asm x86_64, no-asm
         those methods are used by the Karatsuba multiplication algorithm

Tomasz Sowa 277dd72fb6 fixed: UInt::AddInt() in no-asm code has incorrect assertion
changed: UInt::SubInt() in no-asm code is a little faster now
changed: small cosmetic changes in commentaries
deleted: some debug #ifdef's from UInt::Div() (in no-asm code)

Tomasz Sowa 85945b2bb0 added: ttmathuint_x86.h, ttmathuint_x86_64.h, ttmathuint_noasm.h,
all the methods which are using assembler code have been 
         rewritten to no-asm forms, now we have:
         1. asm for x86      file: ttmathuint_x86.h
         2. asm for x86_64   file: ttmathuint_x86_64.h
         3. no asm           file: ttmathuint_noasm.h
            (it's used when macro TTMATH_NOASM is defined)
            The third form can be used on x86 and x86_64 as well and
            on other platforms with a little effort.
            (Temporarily I left there some '#ifdef's for debugging.)
