* marshal.c (emit_struct_conv): Take the native type of
	the field to decide what kind of conv to use if field
	is of type char.

	* marshal.c (mono_pinvoke_is_unicode): Unify auto
	and default.

	* marshal.c (emit_struct_conv_full): Kill this variant
	that doesn't make any sense as structures are marshaled
	in the same way regardless of the charset of the method.

	* metadata.c (mono_type_to_unmanaged): Handle marshalspec
	for char.

	Fixes the regression on MD caused by 1f3cfba3.

When security trimming is requested for sub-path of a location specified in the config file,
make sure that we match such a request to its parent location.

Based on patch from Mike Morano <mmorano@mikeandwan.us>, thanks!

        The overloads of EndReceive and EndSend that have an out SocketError
	parameter do not throw.

	Patch by Sven Groot that fixes bug #659056.

	Fixes bug #659123.

Stuff sometimes appears or disappears here, just use a wildcard.

Windows socket behaviour seems to be slightly different from
Linux/Mac, and Mono.Debugger.Soft was trying to disconnect a socket
that that doesn't get connected, causing an exception at launch.

For some reason it did check the main debugger socket before trying
to disconnect it, but not the console socket, so only apps with
redirected console output would crash.

Issues include: casts not being properly generated for nullable
types, missing cast when the type of a member does not match
the forced serialization type, and incorrect code generated
for handling [XmlText] members.

Use SIGXFSZ on FreeBSD too by checking for the __FreeBSD__ define. Like Apple and OpenBSD, it doesn't have SIGPWR.
