Minor refactor
Fix possible stack corruption in std.net.curl

The HTTP and SMTP structs are used as value types. The delegate created
in onReceiveHeader stores a pointer to this HTTP as it needs to access
this.p so we potentially leak a reference to a stack variable here.

As the Impl struct is always allocated on the heap via RefCounted
storing a pointer to Impl is not an issue. So we move the delegate
generation out of HTTP and into impl to make sure it only stores a
pointer to Impl which will stay valid even if the original HTTP object
is moved.

Also reset some delegates in _basicHTTP and _basicFTP to avoid leaving
references to stack variables around.
Fix Issue 11738 - partialShuffle should actually _be_ a partial shuffle :-)

This patch fixes the problem that partialShuffle was in fact invariably
shuffling the whole of the input, undetected because there were unittests
only for randomShuffle.

As well as the fix I've added some unittests specifically for partialShuffle
to ensure that it works properly, and I've taken the opportunity to tweak a
couple of bits of Ddoc and tidy up the randomShuffle unittests.
fixup deprecation of externalAttributes

- directly access private member internally
- only deprecate the property
add @safe pure nothrow
