LaTeX: add \sphinxnotetitle et al.

In passing I reverted some deprecation I had added at 6bf4059 to some
internals of the sphinxadmonition environment, as it does not look that
pressing anyhow and the redundant namings of two colors in particular
may nevertheless prove useful to user \renewcommand's, as they avoid to
have to refer to \spx@noticetype.

-% It was possible for user to \renewenvironment this to use sphinxheavybox,

-% patch was added to allow the \renewenvironment method to work again for
-% note, hint, important, tip to use sphinxheavybox.
-%
-% Then at 6.2.0, note, hint, important, tip can now access full customization
-% of sphinxheavybox: CSS-named alike options (if used) trigger sphinxheavybox.
-% The \renewenvironment method still works but then only common border width,
-% non-configurable padding, straight corners and no shadow are all implied,
-% as long as the related CSS-named options are not used.
+% The more complex definition below will branch to sphinxheavybox if a certain
+% boolean associated to the notice type is true.  This boolean is set to true
+% whenever a CSS-named alike options for the notice type has been used in
+% sphinxsetup.  The old coding as above would still work, with the new options
+% being then simply ignored.  A user redefinition will probably either use
+% directly sphinxlightbox or sphinxheavybox or something else, with no need to
+% test the boolean.
+%
+% 6.2.0 also adds one layer of mark-up via \sphinxnotetitle etc..., because
+% the former \sphinxstrong{#1}<space> used a too generic \sphinxstrong.  But
+% perhaps the #1 should be passed over to sphinx{light,heavy}box as parameter.
+% Unfortunately replacing these environments with one-parameter environments
+% would be potentially a breaking change.  Anyway, sphinxpackageboxes.sty does not
+% provide a "titled" box; the caption of code-blocks is handled by extra
+% code in sphinxVerbatim.
