Try to make sysctl options slightly more orthogonal:

 - introduce a -o option that displays opaque variables.
 - introduce a -x option that displays opaque variables in full.
 - deprecate -A in favor of -ao and -X in favor of -ax.
 - remove -A and -X from usage() and SYNOPSIS (but not from DESCRIPTION).
 - ignore -a if one or more variables were listed on the command line.
 - deprecate -w, it is not needed to determine the user's intentions.
 - some language and style cleanup in the man page.

This commit should not break any existing scripts.
