[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=942da943f391fae3ce283f7dd8f57f94c7408ad1
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.02.x

Fixes the following security issues:

- CVE-2018-8785: FreeRDP prior to version 2.0.0-rc4 contains a Heap-Based
  Buffer Overflow in function zgfx_decompress() that results in a memory
  corruption and probably even a remote code execution.

- CVE-2018-8786: FreeRDP prior to version 2.0.0-rc4 contains an Integer
  Truncation that leads to a Heap-Based Buffer Overflow in function
  update_read_bitmap_update() and results in a memory corruption and
  probably even a remote code execution.

- CVE-2018-8787: FreeRDP prior to version 2.0.0-rc4 contains an Integer
  Overflow that leads to a Heap-Based Buffer Overflow in function
  gdi_Bitmap_Decompress() and results in a memory corruption and probably
  even a remote code execution.

- CVE-2018-8788: FreeRDP prior to version 2.0.0-rc4 contains an
  Out-Of-Bounds Write of up to 4 bytes in function nsc_rle_decode() that
  results in a memory corruption and possibly even a remote code execution.

- CVE-2018-8789: FreeRDP prior to version 2.0.0-rc4 contains several
  Out-Of-Bounds Reads in the NTLM Authentication module that results in a
  Denial of Service (segfault).

For details, see the upstream PR:
https://github.com/FreeRDP/FreeRDP/pull/5031

Add support to set tls security level (for openssl >= 1.1.0), for RDP
protocol version 10 (needed for windows 10 and windows server
2016). Also have some fix and features, see
