Split interface discovery in three stages: discover available programs
(extcap_get_extcap_paths), obtain outputs for each (extcap_run_all) and
processing of the output (process_new_extcap). The second step is most
expensive, do it in parallel in multiple threads.
extcap_foreach used to call extcap_if_exists, but as "cb_info.ifname" is
always NULL for interface discovery, it would always pass. Remove this
check and all other unused functions.
This saves 100ms startup time on Linux with 7 extcap tools.

extcap_foreach has two purposes: discovery of all interfaces for each
tool and querying info for an extcap interface. Observe that the latter
requires extcap_if_exists(ifname) to be true. This makes extcap_foreach
match exactly one interface, so we can avoid some complexity.

Launching USBPcap without going in the interface options menu exhibits 2 bugs:
- we should restore a value only if it is not an empty string (otherwise USBPcap with an ampty --devices multicheck argument)
- when building the argument list for a non boolean argument not using the default value, do not call g_strconcat. It will
build a string concatenating the option and value (for example "--devices 1" that will be treated as a single argument).
Instead option and value must be given separately to argument list.

In commit v2.3.0rc0-117-g485bc45 (backported to v2.2.0rc0-44-g66721ca),
extcap_prefs_dynamic_vals and extcap_cleanup were added in an attempt to
address dangling pointers.
Unfortunately it is not sufficient:
- A pointer to the preference value is stored in extcap_arg and passed
to the prefs API, but this extcap_arg structure can become invalid
which result in use-after-free whenever the preference is accessed.
- On exit, a use-after-free occurs in prefs_cleanup when the preference
value is being checked.
As the preference subsystem actually manages the memory for the string
value and consumers should only provide a pointer where the value can be
stored, convert the char* field in extcap to char**. This has as
additional benefit that values are not limited to 256 bytes anymore.
extcap_cleanup is moved after epan_cleanup to ensure that prefs_cleanup
does not operate on dangling pointers.
Crash is reproducible under ASAN with: tshark -i randpkt

This patch reads out the stderr messages from an extcap
utility and displays it to an user. It was tested on Qt
but not on GTK, but should work their as well.
On Mac OS/X and Windows the child_watch does not behave
as it was intended. Therefore in extcap_cleanup, the callbacks
are called manually, if and only if, they have not been
called already.
The reason why it displays two error messages is, that
by the time the first one is being displayed, glib has not
returned from the spawned process on Linux yet. So there
is no way to add the stderr correctly, and putting a handler
to stderr into interface_opts will lead to memory errors,
cause then the code tries to access memory outside of its
protection.
