[PATCH 6/7] Remove dependency on the <sys/param.h> header

[Felix Janda <felix.janda@posteo.de>]

The header <sys/param.h> is of BSD origin and is mainly used for
system limit constants such as MAXHOSTNAMELEN.

Remove unecessary inclusions of <sys/param.h> and replace limit
constants by equivalent POSIX constants from <limits.h>.

Signed-off-by: Felix Janda <felix.janda@posteo.de>
