Bumped version to 1.4.1

Changed so that normal XMPP "pings" are always sent when keep alive is enabled. The change to disable the periodic sending of spaces in order to ensure traffic over the socket made the LM clients disconnect periodically with specific gateways. The implementation looks correct but it might be the firewall software that is not handling it correctly. This commit reverts the behaviour to always send the spaces even if the platform supports the TCP keep alive settings.

The blocking dns resolver now works as expected. Fixed up the last bits and and use the blocking dns lookup in the simple test. Next step will be to make a second one that uses asyncns to do the job.

Added test-dns-blocking to ignore file

Removed soup dependencies from the build

Added small test program and simple tests seems to work. Added test-dns-blocking, this program will be removed later though. Also needed to export some internal functions in the library file to get the test program to build. These were lm_resolver_lookup and lm_blocking_resolver_get_type.

Moved MIN_PORT and MAX_PORT to lm-internals.h and renamed them. Now call the LM_MIN_PORT and LM_MAX_PORT to make it clear they are defined inside of Loudmouth. Also more work on the DNS cleanups.

Added GMainContext to LmResolver and use lm_misc_add_idle to add an idle in it. Since we need to use the correct GMainContext it is now being passed to LmResolver and later used in LmBlockingResolver.

Added protocol for srv lookups

More work on the blocking resolver

Implemented the idle "spawn" in LmBlockingResolver. In order to simulate the asynchronous API of LmResolver the synchronous LmBlockingResolver runs in an idle callback. That means the lm_resolver_lookup call will return just as it does in the asynchronous version and instead the result will come through the given callback.

Added LmBlockingResolver which will handle the case when we do not have libasyncns. The blocking resolver will be blocking while waiting for response from a web server.

Added LmAsyncnsResolver

Fixed some spaces

Added type property to LmResolver

Changed so that we create a resolver with various arguments depending on type. Instead of having the lookup_host and lookup_srv virtual methods there is now only one lookup method and the resolver is created using new_for_host or new_for_srv instead. The host or domain/srv values are set as properties on the base class for the sub classes to read out.

Made LmResolver an object for subclassing instead of an interface

Added LmResolver interface. The LmResolver interface will be implemented in one blocking fashion and one implementation that uses Libasyncns. Designing this as an interface will make it easy to implement an asynchronous version using platform specific technologies for Windows and Mac OS X. It will also make it easier to create a mock implementation to simulate various error codes to test the layers using the resolver.

Some style fixes

Refactored some of the SSL code in LmConnection. Added functions to wrap LmSSL functions in LmOldSocket to minimize the number of calls from LmConnection to LmSSL directly. Also split out function to register a STARTTLS handler if it is not already registered and we are using STARTTLS.

Moved the call to _lm_ssl_close to LmOldSocket

Split out old_socket_do_write from lm_old_socket_do_write. The reason for having the buffer setup split out of lm_old_socket_do_write was that it's also used internally in LmOldSocket. Split out the part that should not care about buffered output into old_socket_do_write. Also renamed lm_old_socket_do_write to lm_old_socket_write.

Some more cleanups

Moved the ifdefs for HAVE_ASYNCNS to the LmOldSocket code. This cleans up the code a bit as it leaves the ifdefs to internal in LmOldSocket.

Updated _asyncns_cancel to follow coding style

Made the output buffer functions private to LmOldSocket.

Moved output buffer creation/addition to LmOldSocket where it belongs.

slight style fix

Some more work on the soup socket

Initital start on implementing the various write functions in LmSoupSocket
