gmmproc: Tidy up the generation of enum docs

* tools/m4/gerror.m4: Add "/** " at the start of the documentation,
like enum.m4 does.
* tools/pm/DocsParser.pm: lookup_enum_documentation(): Don't add "/** "
which is deleted by the caller. Add "\n * " with the right indentation.
* tools/pm/Output.pm: output_wrap_enum(), output_wrap_enum_docs_only(),
output_wrap_gerror(): Don't delete "/** ". Don't change indentation.
Regenerate gio .defs.
Regnerate glib .defs.
Regenerate .docs.xml files.
tests/giomm_tls_client: Put try/catch around Socket::connect().

Because it's currently timing out for me.

Tiny comment spelling fix.
gmmproc: Improve the conversion of Since to @newin

* tools/m4/enum.m4: Add a blank line in the enum documentation.
* tools/pm/Output.pm: Don't always add a blank line in the enum documentation.
* tools/pm/DocsParser.pm: Improve the rules for conversion of Since to @newin.
Add an empty line after @newin where it's missing

* gio/src/action.hg:
* gio/src/cancellable.hg:
* gio/src/charsetconverter.hg:
* gio/src/mount.hg:
* gio/src/notification.hg:
* gio/src/simpleaction.hg:
* gio/src/socket.hg:
* glib/src/datetime.hg:
* glib/src/glib_docs_override.xml:
* glib/src/keyfile.hg:
* glib/src/variant.hg: Add an empty line after @newin where it's needed in
order to avoid bad side effects in the documentation. Doxygen assumes that
@newin is followed by a paragraph that describes what is new.
gmmproc: Don't make one very long line for the enum documentation

* tools/pm/DocsParser.pm: lookup_enum_documentation(): Don't replace newlines
by spaces in the description of the enum constants.
Gio::UnixFDList, UnixFDMessage: Fix array lengths in steal_fds()

* gio/src/unixfdlist.[hg|ccg]: Hand-code both constructors that take a
Glib::ArrayHandle<int>, and call g_unix_fd_list_new_from_array() in them.
* gio/src/unixfdlist.ccg: Don't subtract 1 from the length returned by
g_unix_fd_list_[peek|steal]_fds().
* gio/src/unixfdmessage.hg: get_fd_list(): Add refreturn.
* gio/src/unixfdmessage.ccg: Don't subtract 1 from the length returned by
g_unix_fd_message_steal_fds(). Bug #741365.
