Fix the date time set in file by removing the ':'.

This is the same code than the one under SendCore. The date time should
not have the : (time zone offset) to be able to use the file.
[Mono.Parallel] Removed broken Mono.Threading.Tasks code

The code in MonoTaskExtensions.cs relied on the internal method Execute(Action<Task>) in System.Threading.Tasks.Task which was removed in 0a66e60.
add files System.Configuration.dll and System.Security.dll to monolite directory in tarball
to avoid: error CS0006: Metadata file `System.Security.dll' could not be found
make sure that the subdirectories of mcs/class/Facades are included in the tarball

to avoid errors like:
MCS     [net_4_5] System.Xml.Serialization.dll
/bin/sh: line 4: cd: System.Collections.Concurrent: No such file or directory
Mono.Cairo: Add Context.InClip method

The cairo_in_clip function was added in cairo 1.10.
Mono.Cairo: Add Context.HasCurrentPoint property

The cairo_has_current_point function was added in cairo 1.6.
Mono.Cairo: Add Context.SetSourceColor(Color) convenience method

The Color property was obsoleted, but the suggested replacement
SetSourceRGBA has 4 double parameters, which can be unconvenient.

Add a SetSourceColor that takes a Cairo.Color parameter, make the Color
property use it, and update the message on the Obsolete attribute.
[Mono.Debugger.Soft] Using environment variable MONO_SDB_LOG as logfile path
Added stress test to ConcurrentQueue.TryPeek.
The test checks that in some race condition the queue does not return null.
Changed TryPeek to handle race condition with Dequeue.
Dequeue sets the head.Value to its default. When TryPeek is interrupted in the process of retrieving the value some times Dequeue sets the value to its default. TryPeek now checks the head has not been changed before returning the value.
[sdb] Add a lower level lock and use it in place of the loader lock in some places.
Update README.md

Add info on parallel installations which is going to be the case for 99% of people trying to compile and use mono from source.

[Mono.Debugger.Soft] Using environment variable MONO_SDB_LOG as logfile path
MemoryMappedFile fixes

This patch includes a few fixes:

	* CreateNew will actually create a memory map file, the previous logic
	  in MemoryMapImpl.Open was wrong, and would fail if the file did not
	  exist.   We now cope with this (bug #20052 was caused by this).

 	* Some exceptions were wrong, so this patch updates the
	  exceptions being thrown to be the right ones

	* On Mobile, we inverted the logic to ensure that capacity must be
	  bigger or equal than the file size (which is what the API needs to do),
	  previously it performed the opposite test.

Added tests that match the behavior on .NET for this.

Print the correct GC type if compiling using --with-gc=none.

Allow building with null-gc and sgen.
Previously if --with-gc=none --with-sgen=yes was specified the sgen runtime
would include the null GC and the sgen GC which would confuse the linker.

This change released uner the MIT license.
