Version 0.1.11 2018-10-30
- portability: remove issues associated with AC_FUNC_MALLOC
  This configure.ac macro is known to cause issues and not provide real
  benefit. Thus many projects have removed it, as we have for most of
  the rsyslog projects. libestr seemed to have overlooked.
  This came up when troubleshooting issues on IBM AIX.
- make build on AIX
  Thanks to github user purnimam1 for the patch
- bugfix: es_str2num mishandling empty strings
  If es_str2num() receives an empty string, misadressing happens.
  Under extreme conditions, this theoretically can lead to a segfault.
  Thanks to Jan Gerhards for the patch.

- CI/Travis: now also test on osX

Version 0.1.9 2013-10-28
- bugfix: invalid number string when creating string from integer 
  Thanks to Pavel Levshin for the patch
----------------------------------------------------------------------
Version 0.1.8 2013-10-16
- bugfix: previous fix for string comparisons did not work properly
  Thanks to Tomas Heinrich for alerting us
----------------------------------------------------------------------
Version 0.1.7 2013-10-10
- bugfix: invalid comparison results for different-length strings
  es_strcmp, es_strcasecmp, es_strbufcmp, and es_strcasebufcmp
  returned incorrect results if the first string was smaller than
  the second. In that case, the first string was always assumed
  to be lexially lower than the second. If the second string was
  larger than the first, the same issue occured. This did not affect
  equal comparisons, but LT/GT checks lead to invalid result, with
  potentially harsh consequences (e.g. qsort() did not work properly).
  This bug is present for a very long time, potentially down to the
  initial implementation of libestr.
