Remove the buggy and complex awk(1) magic in "plugins-scripts/subst.in"
in favor of simple sed(1) substitutions.
The plugins in the "plugins-scripts" directory now always use the PATH
specified via "./configure --trusted-path", or the default PATH
hard-coded in "configure.ac".
Fixes#1242.
'use lib utils.pm' is not valid Perl syntax:
Bareword "utils" not allowed while "strict subs" in use at plugins-scripts/check_ircd.pl line 52.
Bareword "pm" not allowed while "strict subs" in use at plugins-scripts/check_ircd.pl line 52.
This makes it impossible to use the plugins directly from the git tree,
e.g. while hacking on them.
Using FindBin::Bin as the library path allows that, while preserving
the original behaviour of adding the libexec path when the plugin is
properly installed.
When configuring the plugins you have the option to specify a trusted path with --with-trusted-path. This option seems to have been deprecated at some point for unknown reasons and had typically had no affect. This commit makes this option work again for those who have a desire to use it. There should be no affect on those who have not chosen to specify a trusted path.
