* Always compile with -ldl when building for CODE_COVERAGE
When building with CODE_COVERAGE, the afl runtime contains code that
calls `dladdr` which requires -ldl. Under most circumstances, clang
already adds this (e.g. when building with pc-table), but there are some
circumstances where it isn't added automatically.
* Add visibility declaration to __afl_connected
When building with hidden visibility, the use of __AFL_LOOP inside such
code can cause linker errors due to __afl_connected being declared
"hidden".
* Update docs to clarify that CODE_COVERAGE=1 is required for dynamic_covfilter
- Check if too many cmdline params here, each time before insert a new param.
- Check if it is "-fsanitize=..." before we do sth.
- Remove improper param_st transfer.
