Verified with running tests with new "-e" run-tests arg:
$ make test TESTS=Zend/tests/*-on-non-objects-*phpt TEST_PHP_ARGS=-e
# Tests passed : 11 (100.0%)
$ make test TESTS=Zend/tests/*-on-non-objects-*phpt
# Tests passed : 11 (100.0%)
Before, this would cause a SEGV. Thanks @nikic for raising this concern
In PHP-5.6 and below each argument passed to user function was copies on VM stack twice.
Now we always have ZEND_INIT_FCALL (or simular) opcode that pushes "call frame" on top of VM stack.
"Call frame" is actually the same zend_execute_data structure.
All the following ZEND_SEND instructions push arguments on top of the stack in a way that they directly comes into corresponding CV variables of the called frame. Extra arguments are copied at the end of stack frame (after all CV and TMP variables) on function enterance.
There are two minor incompatibilities:
1) It's not allowed to decalre functions redefining arguments e.g. "function foo($a,$a) {}".
2) func_get_arg() and func_get args() return the current value of argument and not the original value that was sent.

Add NEWS. This doesn't need UPGRADING (or an RFC), IMO.
Fix broken test.
Add a mime type map generation script and update the header.
Move the mime type map out of php_cli_server.c for easier generation.
Replace the CLI server's linear search for extensions with a hash table.
