* Revert "Extend "read_argv" native"
This reverts commit aaa2934595379c371513cb9dd23de8f3c5e16d93.
This broke binary compatibility with either older, already compiled
plugins, or newly compiled plugins if you forgot to update .inc headers.
This happened because read_argv used to receive maxlen by value, and
after
this commit it receives it by reference. This causes read_argv either
to fail, or worse, to buffer overflow, resulting in a security vulnerability.
Newly introduced functionality for read_argv should be added with a new,
separate native.
* Add "read_argv_int" & "read_argv_float" natives
