This extends the socket infrastructure in libosmocore to allow
to create non-blocking sockets.
Basically, it replaces the connect0_bind1 parameter by one
flags parameter.
autoconf >=2.68 demands the body of an AC_COMPILE_IFELSE to be wrapped in
an AC_LANG_SOURCE macro, otherwise outputs annoying warnings on the
invocation of `autoreconf -i`. this patch follows that demand.
and export the underlying raw value_string arrays instead:
abis_nm_obj_class_names / abis_nm_adm_state_names.
This permits the caller to use get_string_value() as well as
get_value_string().
osmo_sock_init_ofd() is a wrapper around osmo_sock_init() which will
take care of initializing and registering a 'struct osmo_fd' for the
newly-created socket.
* use write_queue where applicable
* provide functions that work on raw FD and those with osmo_fd
* add support for multiple gsmtap instances (no global variables)
Harald reported a problem in the logging:

Reverting 81e9636454 seems to
fix the problem. However, that workaround looks ugly.
Holger gives us another clue on what was wrong:
http://lists.osmocom.org/pipermail/openbsc/2011-May/002905.html
While digging in the manpage, I found this:
"The functions vprintf(), vfprintf(), vsprintf(), vsnprintf()
are equivalent to the functions printf(), fprintf(), sprintf(),
snprintf(), respectively, except that they are called with a
va_list instead of a variable number of arguments. These functions
do not call the va_end macro. Consequently, the value of ap is
undefined after the call. The application should call va_end(ap)
itself afterwards."

The plan is to collect structs and routines for application
setup and remove many copies of the boilerplate code we have
right now. This starts with routines to ignore certain signals
and the stderr init code.
Increment the age of the library because a new interface was added.

minor glitch included in this patch while I was at it:
-#include "linuxlist.h"
+#include <osmocom/core/linuxlist.h>
This can be helpful where we send GSMTAP messages to the loopback
device (localhost, 127.0.0.1) from where the kernel would then
send ICMP reject packets as nobody is listening on that port.
This patch removes a workaround to fix some strange memory corruption
now that _output() has been completely reworked and we make use of
snprintf appropriately.
