The watchOS device has limited networking support; in particular
it does not allow inbound/output network connections using 'bind'
(kernel-level sandbox restrictions).
This means that we can't use BSD sockets to connect to the debugger
in the IDE on the desktop. Instead we create an http tunnel that
knows how to convert socket send/recv data into http requests on
both sides.

Launching a watchOS extension on device with the managed debugger
attached is slow, which means that the launch watchdog will kick in
and kill the app before it has launched.
So we attach the native debugger as well, which prevents the launch
watchdog from killing the app. Incidentally it also makes watchOS
not background the app.
We're using private API to determine whether a native debugger is
attached, but it's only in debug code, and as such would not be
included in release builds for customer apps. Also the code is
currently limited to watchOS since it's not needed on other
platforms for now.
64-bit iOS 9+ devices have a pagesize of 16kb (even when running 32-bit apps).
This means all executable code must have sectors aligned to 16kb when running
on such devices.
The native linker uses the min iOS version to determine the sector alignment;
if min iOS version is < 8.0, then the sector alignment is 4k, otherwise 16k.
This means that when we create our 32-bit dylibs we must link them with a min
iOS version of 8.0, or they won't work on a 64-bit device in a 32-bit app (bug
So change our makefiles to link armv7[s] dylibs with min iOS version 8.0.

The real fix for bug #43658 is in mono master, but the current
version of mono master doesn't build for us, so implement this
workaround instead.
The problem is that the linker doesn't preserve fields of nested types marked
in xml descriptions unless the declaring type is marked. So the workaround
(until we can bump mono) is to mark the declaring type.

Native code can provide the same native method for blocks
with different managed signatures, so it's not enough
to hash by method address, we need to take the target type
of the delegate into account as well.

* Bump [watch-]mono to master to get fix for #43658.

* [mtouch/mmp] Fix build after breaking cecil update in mono.
Also use mono's cecil instead of our own cecil submodule for mtouch.
* Bump [watch-]mono to get compilation fixes after cecil bump in mono.
* Remove cecil submodule, we only use the one in mono now.
This way we use the right version of any dependent dlls.
Otherwise we'd build with the cecil version from the mono repository,
and run with the system's cecil.
* [Mtouch] Use the mono tools to copy over the msym files.
* As per review:
* Do not create a DirectoryInfo when it is not needed.
* Do not throw exceptions for values that can be null, should never
happen.
* Remove unused import.
* Undo a wrong using removal and do the right thing.
* Fix build issues.
