ctrl: on parse errors, return a detailed message to sender
The recently added ctrl_cmd_parse2() returns non-NULL cmd with error messages
upon parsing errors. In handle_control_read(), use ctrl_cmd_parse2() and send
those back to the CTRL command sender as reply.
Retain the previous "Command parser error" reply only in case
ctrl_cmd_parse2()
should return NULL, which shouldn't actually happen at all.

add ctrl_cmd_parse2() to return parsing errors
If a control command fails to parse, we so far discard specific error messages
and instead send just "Command parser error".
In ctrl_cmd_parse() we actually compose detailed error replies, but in the end
simply talloc_free() them and return NULL.
A first step to report these errors to the ctrl command issuer is to not return
NULL and instead return the cmd with type = CTRL_TYPE_ERROR. Add
ctrl_cmd_parse2() to return such instead of NULL.
To stay API compatible, provide ctrl_cmd_parse2() to return a cmd on errors.
ctrl_cmd_parse() retains identical behavior but becomes just a simple wrapper
around ctrl_cmd_parse2() which discards the cmd on error.
No need really to deprecate ctrl_cmd_parse() yet; especially as long as
compiler warnings might break jenkins builds.

ctrl: fix mem leak when handling GET_REPLY and SET_REPLY
In ctrl_handle_msg() (code recently propagated from handle_control_read()),
talloc_free() the parsed ctrl_cmd in all code paths. In particular, a free was
missing in case ctrl_cmd_handle() returns CTRL_CMD_HANDLED.
CTRL_CMD_HANDLED is triggered by GET_REPLY / SET_REPLY parsing, as show by
ctrl_test.c. With the memleak fixed, adjust expected test output and make a
detected mem leak abort the test immediately.

ctrl_test: show memleak when receiving GET_REPLY and SET_REPLY commands
The "memleak!" output shows messages that lack a talloc_free() of the
parsed
ctrl command buffer. The leak shall be fixed in a subsequent patch.

ctrl_test: expand to test message handling and detect mem leaks

ctrl: prep test: separate new ctrl_handle_msg() from handle_control_read()
In order to allow unit testing the ctrl iface msgb handling, have a separate
msgb entry point function from the actual fd read function.
An upcoming patch will prove a memory leak in CTRL msgb handling by a unit test
that needs this separation.

ctrl_test.c: replace print_escaped() with new osmo_escape_str()

utils: add osmo_escape_str()
To report invalid characters in identifiers, it is desirable to escape any
weird characters. Otherwise we might print stray newlines or control characters
in the log output.
ctrl_test.c already uses a print_escaped() function, which will be replaced by
osmo_escape_str() in a subsequent patch.
control_cmd.c will use osmo_escape_str() to log invalid identifiers.
