log: remove increasing windows usage in fastpath

The purpose of increasing windows is to allow backwards iteration on the
filelog  at a reasonable cost.
But is it needed?
 - if follow is False, we have no reason to iterate backwards.
   We basically just want to walk the complete filelog and yield all revisions
   within the revision range. We can do this forward or
   backwards, as it only reads the index.
 - when follow is True, we need to examine the contents of the filelog, and to
   do this efficiently we need to read the filelog forward.
   And on the other hand, to track ancestors and copies, we need to process
   revisions backwards. But is it necessary to use increasing windows
   for this?
   We can iterate over the complete filelog forward, stack the revisions, and
   read the reversed(pile), it does the same thing with a more readable code.

# The config file looks like this.  You can have paths to individual
# repos, collections of repos in a directory tree, or both.
#
# [paths]
# virtual/path = /real/path
# virtual/path = /real/path
#
# [collections]
# /prefix/to/strip/off = /root/of/tree/full/of/repos
#
# collections example: say directory tree /foo contains repos /foo/bar,
# /foo/quux/baz.  Give this config section:
#   [collections]
#   /foo = /foo
# Then repos will list as bar and quux/baz.

# Alternatively you can pass a list of ('virtual/path', '/real/path') tuples
# or use a dictionary with entries like 'virtual/path': '/real/path'
