pptp-1.10.0-bp160.1.13

- Use %autosetup macro. Allows to eliminate the usage of deprecated
  %patchN.

- bsc#1194714: Remove pptp-command (the former SysV init scirpt).
  It has been broken for a long time (seeking deprecated ifconfig
  in the wrong location) without any complaints, so it seems safe
  to assume it is not being used anymore.

- boo#1191717: The upgrade to 1.10.0 also fixes an issue in
  combination with Microtic routers.

- Update to versioin 1.10.0
  * remove inststr in favour of prctrl PR_SET_NAME,
  * vector tests; include in make, fix code rot, fix return status,
  * pqueue; include missing sys/types.h,
  * pptpsetup; prevent world-readable peers file, use
    three-argument append, allow password trailing spaces, split
    prints to chap-secrets, allow passwords with quotes, use
    absolute path to pptp
  * remove uid from ip route get output; iproute2-4.10 and later
    may emit uid, (bsc#1131960).
- Changes in 1.9.0
  * close a memory leak in pqueue,
  * avoid clobbering heap (RHBZ #1183627),
  * fix use after free in call close request handler,
  * add --missing-window option (Debian #680455, Ubuntu #681617),
  * randomise call-id (Debian #721963),
  * replace gethostbyname(3) with getaddrinfo(3),
  * don't set build flags; use defaults,
  * fix for (null) in "pptp: GRE-to-PPP gateway on (null)".
