Subject: toolbox: Make have(), _try_include(), include() read-only
X-Git-Url: https://git.corax.cc/?a=commitdiff_plain;h=394e5ac616303b237a70a6ad9fc7c0e170c9c201;p=toolbox

toolbox: Make have(), _try_include(), include() read-only

Functions from toolbox.sh may be redeclared, causing all sorts of
problems from simple bugs to security issues.
This commit makes sure the functions are declared read-only when
toolbox is loaded so the user can't shoot themself in the foot.
