Rename directories and parameteres to be more descriptive

Browse Source 
* squashfs images that will be part of read-only branchs for union mount in /
  are mounted on /ro_branch/{image_name} instead of /tmpfs/mnt/{image_name}
  (and avoid empty dirs on live env under /mnt)
* tmpfs that will be part of read-write branch for union mount in /
  is mounted on /rw_branch instead of /tmpfs
* tmpfs that is for store *.sqfs images when copytoram=y, is mounted on
  /copytoram instead of /tmpfs.sqfs

* tmpfs_size= parameter renamed to rw_branch_size=
* tmpfs_sqfs_size= parameter renamed to copytoram_size=
