Rename C names to match Lisp symbols better

This was inspired by commit e65c3079c65595d95749348366af9811fafff062,

symbol name itself.  Fix other instances of disagreements that I found.
Although this doesn’t fix a bug, it should make code easier to follow.

Fix an Isearch var to be a string (Bug#23038)

* isearch.el (isearch--describe-regexp-mode): The `description' var
  needs to always be a string.  Add the missing default case for the
  cond form that ensures that.

Before this bug fix, for the events when `regexp-function' and
`search-default-mode' both were nil, `description' also stayed nil.  So
when `space-before' was non-nil, the "non-string" `description'
(with a value of nil) got passed as an argument to
`replace-regexp-in-string' (where a string was expected).  That caused
the error described in Bug#23038.

Fix (args-out-of-range 1) error in cursor-sensor--detect

* lisp/emacs-lisp/cursor-sensor.el (cursor-sensor--detect): Don't

Resurrect earlier fix of resize_frame_windows

* src/window.c (resize_frame_windows): Resurrect earlier fix for
calculating the number of columns of the minibuffer window which
was lost in subsequent merges.

Move the cert files to the data directory

Further empty <li> tweaks

* lisp/net/shr.el (shr-tag-li): When showing several empty
<li> elements, ensure that they really get inserted on a new line.

Don't remove too much white space at the end of documents

* lisp/net/shr.el (shr--remove-blank-lines-at-the-end): Don't
remove too much white space -- leave it on the last line (in
case there's a background color).

Amend parse-partial-sexp correctly to handle two character comment delimiters

Do this by adding a new field to the parser state: the syntax of the last
character scanned, should that be the first char of a (potential) two char
construct, nil otherwise.
This should make the parser state complete.
Also document element 9 of the parser state.  Also refactor the code a bit.

* src/syntax.c (struct lisp_parse_state): Add a new field.

when that character might be the first of a two character construct.
(Fforward_comment, scan_lists): New dummy variables, passed to forw_comment.
(scan_sexps_forward): Remove a redundant state parameter.  Access all `state'
information via the address parameter `state'.  Remove the code which converts
from external to internal form of `state'.  Access buffer contents only from
`from' onwards.  Reformulate code at the top of the main loop correctly to
recognize comment openers when starting in the middle of one.  Call
forw_comment with extra argument (for return of syntax value of possible first
char of a two char construct).
(Fparse_partial_sexp): Document elements 9, 10 of the parser state in the
doc string.  Clarify the doc string in general.  Call
internalize_parse_state.  Take account of the new elements when consing up the
output parser state.

* doc/lispref/syntax.texi: (Parser State): Document element 9 and the new
element 10.  Minor wording corrections (remove reference to "trivial
cases").
(Low Level Parsing): Minor corrections.

* etc/NEWS: Note new element 10, and documentation of element 9 of parser
state.
