Fixes Issue 6224 - Add ownerTid() property.
Remove Tid.send() duplicated function, as UFCS function can take its place.
Fixes Issue 9260 - std.getopt: Implement boolean parsing with optional argument.
Throw RangeError
issue 5013
Finally remove std.regexp.

It's been deprecated for some time now, and we no longer have anything
in Phobos which depends on it. So, it's long past time for it to be
fully removed.

std.process: Add an additional unit test for escapeShellCommand (issue 9310)
issue 5310
Deprecate std.metastrings.

std.metastrings is no longer required, because the corresponding
normal functions work in CTFE, and std.metastrings is actually very
inefficient.
Added CTFE-ability tests to some stuff in std.conv and std.string.

These tests are for the functionality that std.metastrings provides, and
we need to ensure that the normal functions which are replacing
those in std.metastrings continue to work in CTFE.
