* Revert "Extend "read_argv" native"
This reverts commit aaa2934595.
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
* Fix floatround overflow
floatround would overflow for floats greater than 2^30 because internally
it would double the number (therefore anything greater than 2^30 results
in something greater than 2^31 which would cause overflow of course)
floatround behaviour is left exactly identical otherwise (although I find
it very weird and wrong to deliberately avoid banker's rounding, it would
be a bad idea to change this behaviour due to compatibility)
Remember to reassemble amxexecn and amxjitsn
* Update the compiled object files
