* Added TextElementBranch that uses a slot as the conditional.

* Added timeout to WindowText and updated download and peer info.

* Moved default http agent string to rtorrent/configure.ac.

* Periodic syncing of chunks now tries to only sync tightly packed
  ranges of chunks unless timeout_sync has been reached.

* ChunkManager now checks if max memory is set to RLIM_INFINITY, if so
  use 2^32.

* Added safe_sync option that forces MS_SYNC to be used before
  unmapping chunks.
