Tomasz Sowa c73af9c116 - changed info in headers in source files: (new) BSD licence -> 3-Clause BSD Licence 
- added svn:ignore in some places




git-svn-id: svn://ttmath.org/publicrep/ttmath/trunk@1051 e52654a7-88a9-db11-a3e9-0013d4bc506e

Tomasz Sowa e2cdeac423 fixed: in x86_64 asm code (for Win64) there were in some places the esp register used, 
there should be rsp used instead
       (reported by Villi on the tttmath forum)

Tomasz Sowa 362207e2f1 added some missing methods: ToUInt, ToInt, FromUInt, FromInt in Big<> class

Tomasz Sowa 4c0d8c26ff changed: small optimization in ttmath_subindexed_x64() 
(asm for x86_64 on MS VC)
changed: removed some MS VC warnings
changed: if TTMATH_DEBUG_LOG is defined then UInt::UInt()
         constructor fills the table with special values
added:   macro: TTMATH_BITS(min_bits)
         which returns the number of machine words
         capable to hold min_bits bits

Tomasz Sowa 9ccacd8817 added: uint __fastcall ttmath_addvector_x64(const uint * ss1, const uint * ss2, uint ss1_size, uint ss2_size, uint * result); 
uint __fastcall ttmath_subvector_x64(const uint * ss1, const uint * ss2, uint ss1_size, uint ss2_size, uint * result);
       asm code for AddVector() and SubVector() for MS VC x86_64
changed: added prefixes "ttmath_" to all public procedures from ttmathuint_x86_64_msvc.asm

Tomasz Sowa e13e5eb329 added: flag TTMATH_BIG_ZERO to Big<> class 
if this flag is set then there is a value zero
added:   Big::ClearInfoBit(unsigned char)
         Big::SetInfoBit(unsigned char)
         Big::IsInfoBit(unsigned char)
         some methods for manipulating the info flags
changed: IsZero() is using TTMATH_BIG_ZERO flag
         now it has O(1) complexity
         previously was O(n)
changed: optimized some methods
         they are using IsZero() for testing at the beginning
         because this method is much faster now
changed: Big::Div(ss2)
         Big::Mod(ss2)
         they return 2 when ss2 is zero
         previously returned 1

Tomasz Sowa 28964d30f7 merged: x86_64 asm code for Microsoft Visual compiler 
file: ttmathuint_x86_64_msvc.asm from chk branch (original was: ttmathuint_x86_amd64_msvc.asm)
        (this file should be compiled first because MS VC doesn't support inline assembler in x86_64 mode)
