proj/gentoo: Initial commit

This commit represents a new era for Gentoo:
Storing the gentoo-x86 tree in Git, as converted from CVS.

This commit is the start of the NEW history.
Any historical data is intended to be grafted onto this point.

Creation process:
1. Take final CVS checkout snapshot
2. Remove ALL ChangeLog* files
3. Transform all Manifests to thin
4. Remove empty Manifests
5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$
5.1. Do not touch files with -kb/-ko keyword flags.

+    LibTomMath is a free open source portable number theoretic multiple-precision 
+    integer library written entirely in C. (phew!). The library is designed to 
+    provide a simple to work with API that provides fairly efficient routines that 
+    build out of the box without configuration.
+
+    The library builds out of the box with GCC 2.95 [and up] as well as Visual C++ 
+    v6.00 [with SP5] without configuration. The source code is arranged to make it 
+    easy to dive into a particular area very quickly. The code is also littered with 
+    comments [This is one of the on going goals] that help explain the algorithms and 
+    their implementations. Ideally the code will serve as an educational tool in the 
+    future for CS students studying number theory.
+
+    The library provides a vast array of highly optimized routines from various 
+    branches of number theory.
+
+      * Simple Algebraic
+            o Addition
+            o Subtraction
+            o Multiplication
+            o Squaring
+            o Division 
+      * Digit Manipulation
+            o Shift left/right whole digits (mult by 2b by moving digits)
+            o Fast multiplication/division by 2 and 2k for k&gt;1
+            o Binary AND, OR and XOR gates 
+      * Modular Reductions
+            o Barrett Reduction (fast for any p)
+            o Montgomery Reduction (faster for any odd p)
+            o DR Reduction (faster for any restricted p see manual)
+            o 2k Reduction (fast reduction modulo 2p - k)
+            o The exptmod logic can use any of the four reduction algorithms when 
+              appropriate with a single function call. 
+      * Number Theoretic
+            o Greatest Common Divisor
+            o Least Common Multiple
+            o Jacobi Symbol Computation (falls back to Legendre for prime moduli)
+            o Multiplicative Inverse
+            o Extended Euclidean Algorithm
+            o Modular Exponentiation
+            o Fermat and Miller-Rabin Primality Tests, utility function such as 
+              is_prime and next_prime 
+      * Miscellaneous
+            o Root finding over Z
+            o Pseudo-random integers
+            o Signed and Unsigned comparisons 
+      * Optimizations
+            o Fast Comba based Multiplier, Squaring and Montgomery routines.
+            o Montgomery, Diminished Radix and Barrett based modular 
+              exponentiation.
+            o Karatsuba and Toom-Cook multiplication algorithms.
+            o Many pointer aliasing optimiztions throughout the entire library.
