CVE-2019-17041: Fixed a heap overflow in the parser for AIX log messages (bsc#1153451).

CVE-2019-17042: Fixed a heap overflow in the parser for Cisco log messages (bsc#1153459).

Non-security issues fixed: Handle multiline messages correctly when using the imfile module. (bsc#1015203)

Fix a race condition in the shutdown sequence in wtp that was causing rsyslog not to shutdown properly. (bsc#1022804)
