All those logging functions already add a newline to any message they
print, so there’s no need to add a trailing newline in the message
passed to them.

Very many testcases, some GLib tools (resource compiler, etc) and
GApplication were calling g_type_init().

Remove those uses, as they are no longer required.

This can be used for debugging, or for progress UIs ("Connecting to
example.com..."), or to do low-level tweaking on the connection at
various points in the process.

Remove the GError argument from g_thread_new() and abort on failure.
Introduce g_thread_try() for those who want to handle failure.

And remove the 'joinable' argument from g_thread_new() and
g_thread_new_full().

Change the wording in the docs.  Clarify expectations for
(deprecated) g_thread_create().

GSocket has a timeout flag now, but when using GSocketClient there was
no way to set the timeout until after connecting (or failing). Fix
that by adding a timeout property to GSocketClient.

Also update gio/tests/send-data.c to test async connection, and free
more stuff in several tests to make leaks easier to see.

This reverts commit 2262d76b33094304ece0d0d9cd5920682599a49b.

Move GIO tests back to where they belong.

This avoids getting tests built every time when working on libgio and
running make in the gio/ directory.
