Summary description:  Mathematical tools to use with amsmath

Announcement text:

 Since the last release (2015) the following issues have been addressed:

 * Changed amsmath requirement to 2016/11/05 (in order to use the aligned fix)

 * Applied the amsmath aligned fix to multlined, now the left part aligned
   Reported by campa in a note to <https://tex.stackexchange.com/a/369212/3929>

 * Reimplemented `\DeclarePairedDelimiter` and friends to fix the following problem:

                 \mathclose{\rvert}^2 vs \mathclose\rvert^2

     They might not give the same result (depending on the font setup).
     Thus the internal wrappers need to be changed into three
     branches: star, nostarnonscaled, nostarscaled, where the
     difference between the last two is whether or not braces are
     applied to the fences.

     This problem was reported in <https://tex.stackexchange.com/q/364308/3929>

 * Since we were cleaning up `\DeclarePairedDelimiter` and friends,
   `\DeclarePairedDelimiterX` is now implemented as a call to
   `\DeclarePairedDelimiterXPP` with empty pre- and postcode.

 * The \DeclarePairedDelimiter(X,XPP) reimplementation removes a
   grouping issue reported in

 * Since there is no longer any `nostar` wrapper branch, redeclaring
   the `nostar` wrapper will now give an error.

 * Removed `-\jot` from the multlined implementation (invisible line).
   Issue reported in at least
       <http://tex.stackexchange.com/a/258162/3929> and
   It is not 100% correct, but better than with `-\jot`.

 * Fixed bug in empheq in relation to AMS clases

 * Renamed macros in mhsetup, mathtools and empheq such that any
   xxx_yyy: macro should now contain EQ, MH or HT as a prefix or infix.
   Thus making everyting truely separate from expl3 defined syntax.

 * Changed \shortintertext such that as long as 'original-intertext=false'
   (the default),
   \shortintertext now only work in the same context as \intertext

 * \shortintertext is now also an error inside the empheq construction

 * Sporadic space fixed in \noeqref, reported by Christian Vetter (private email)

 * Added \ignorespaces after \noindent (intertexts), bug inherited from amsmath
