Fix Issue 8676 (2)

lockstep's stopping policy default value isn't documented because it's set inside the function definition. Once Issue 8687 (http://d.puremagic.com/issues/show_bug.cgi?id=8687) is fixed we'll be able to set the default value in the function header.
Get rid of transitional lfs API

Those kind of functions should be placed in druntime,
but the *64 (v) functions as a public interface are actually
deprecated and shouldn't be used anymore.

Druntime takes care that the normal stat, fopen, calls support
large files, if __USE_FILE_OFFSET64 is defined (which is what
the new C API does as well)

Note: It's actually important to use the functions from
core.sys.posix.stdio as the functions in core.stdc.stdio
are not large file aware. This is probably a bug in druntime.
fix issue 8709, from documentation
Made it so that deprecated functions in std.string are undocumented.
Fix modules which incorrectly use std.string's public imports.

Now, they should be correctly importing for the functions publicly
imported by std.string so that if those public imports are ever removed,
they won't break.
Remove std.ctype from the index.
Undocumented September deprecations.

The deprecated stuff scheduled for removal in September is now
undocumented and marked (in a normal comment) for removal in March 2013.
Undocumented the overload of canFind which was scheduled for deprecation.

It hasn't actually be deprecated, but it's now undocumented and marked
for possible deprecation in the future.

fix issue 8737 Unqual for AA
{SD}List [front|back] primitives

Just some minor details:
* Adding void [front|back](T value) for DList and DList.Range.
* A few missing ddocs in both.
* A few missing enforcement checks.

We *may* want to change some of the enforce into asserts, but right now, there was nothing, and it was inconsistent.
Tighter type checking for SortedRange
Tweak in /pop(Front|Back)/
Fixed link to the other Schwartz in documentation
Current check for additional parents uses "is(typeof())" and thus types given as a parameter are nor fully qualified, nor rejected. Changed this to more generic __trait(compiles) to allow wider usage as same implementation applies.

Improve std.traits unittests

* improve `isAssignable` unittests
* add immutable(S) test to `hasElaborateCopyConstructor`
* add const(S) test to `hasElaborateAssign`
