Rather than making the C library search for git every time we want to execute it we now search for the main git wrapper at startup, do symlink resolution, and then always use the absolute path that we found to execute the binary later on. This should save us some cycles, especially on stat challenged systems like Cygwin/Win32. While I was working on this change I also converted all of our existing pipes ([open "| git ..."]) to use two new pipe wrapper functions. These functions take additional options like --nice and --stderr which instructs Tcl to take special action, like running the underlying git program through `nice` (if available) or redirect stderr to stdout for capture in Tcl.
