  Use git_buf for path storage instead of stack-based buffers
  
  This converts virtually all of the places that allocate GIT_PATH_MAX
  buffers on the stack for manipulating paths to use git_buf objects
  instead.  The patch is pretty careful not to touch the public API
  for libgit2, so there are a few places that still use GIT_PATH_MAX.
  
  This extends and changes some details of the git_buf implementation
  to add a couple of extra functions and to make error handling easier.
  
  This includes serious alterations to all the path.c functions, and
  several of the fileops.c ones, too.  Also, there are a number of new
  functions that parallel existing ones except that use a git_buf
  instead of a stack-based buffer (such as git_config_find_global_r
  that exists alongsize git_config_find_global).
  
  This also modifies the win32 version of p_realpath to allocate whatever
  buffer size is needed to accommodate the realpath instead of hardcoding
  a GIT_PATH_MAX limit, but that change needs to be tested still.
