[dynarray.cons] Move Throws: paragraph to be last, as is customary.

Thanks to Alisdair Meredith! Closes #130.
[dynarray.overview] Clean up ordering of members in dynarray synopsis.

Thanks to Alisdair Meredith! Closes #130.
[optional.inplace] Remove redundant explanation of in_place_t.

The existing wording in this paragraph is already normatively covered
by [optional.object.ctor], so refer there. This also removes the
term "argument pack" that isn't defined by the standard.

Also shorten "constructor and function overloading", since in_place_t
is in fact not used to disambiguate anything but constructors.

Thanks to Alisdair Meredith for pointing out the incorrect term
"argument pack".
Many sections: Use uniform placement of "*" following types.

For example, instead of "char *foo", use "char* foo". This follows the
prevailing style in the draft.

Some specific cases were left alone, most notably cases where multiple
declarations appeared in a single statement (e.g. "char foo, *bar").

This makes the style of pointer types nearly entirely consistent, and
fixes some really egregious examples of different styles used in the
same areas - sometimes even on the same line!
Fix accidental transposition introduced in previous commit.

This fixes a "return* this" introduced in ce29631dccd86d1e1eefff24d1dd3420c598258d.
