inets: Remove use of default gen_server timeout

If you need a timeout between client and server use a server side
timeout instead of the default gen_server:call/2 timeout that is quite
useless. Also remove legacy code that has no further use.

wx: Fix LDFLAGS for Mac

MacOSX min version must be applied to LDFLAGS otherwise linking with static
wxWidgets libraries doesn't work.
wx: Fix crash when garbage collect event handlers (debugger caused seg fault)

wxStyledTextCtrl had no wrapper class so, because it was not detected
that it had virtual destructors, thus references to it was not cleaned
up on destruction. When a process dies and wx cleans up the event handlers
access was made to the deleted object and caused a seg fault.

Added a testcase which I thought could provoke the bug but didn't.

ssl: fix elliptic curve selection in server mode

The server code erroneously took the list of curves supported by the
client from it's own hello extension, effectively breaking curve
selection all together.

Also the default fallback secp256k1 curve is not supported by
all clients. secp256r1 is recommended as part of the NIST Suite B
cryptographic suites. The chances are much better that all clients
support it, so use that as fallback.

wx: Fix hanging wx calls

wxWakeUpIdle doesn't always work on wxGTK and the workaround is to
periodically invoke it, so the gui-thread doesn't get stuck in poll.

Previously it was only called when NOT in batch mode, however if the
wxWakeUpIdle call after a batch_begin command did not wake up the
thread it would still get stuck in poll.
