    Use search-based fontification for $...$ (bug#33139)
    
    It turned out that using "text quotes" syntax for "$" in
    `font-lock-syntax-table' sometimes leads to scrambled fontification
    about in-line math $...$ (bug#33139). That's because conflicting
    results of `syntax-ppss' are compiled into syntax-ppss cache as
    explained in:
    https://lists.gnu.org/archive/html/emacs-devel/2020-05/msg02725.html
    We, Keita, Tassilo and Arash discussed this issue and decided to use
    search-based fontification for $...$ since syntactic fontification for
    $...$ doesn't seem prospective with regard to this bug.
    
    * font-latex.el (font-latex-match-dollar-math):
    
(font-latex-find-dollar-math,font-latex-extend-region-backwards-dollar-math):
    New functions to do search-based fontification for $...$.
    Fontification facility for $$...$$ is merged into them.
    (font-latex-make-user-keywords,font-latex-setup): Use new functions.
    (font-latex-syntax-alist): Don't change syntax of "$" during font lock.
    (font-latex-syntactic-face-function): Simplify.
