[nongnu] elpa/emacsql 8f3d0d4b81 344/427: Use font-lock-flush and font-lock-ensure if available

[ELPA Syncer]

branch: elpa/emacsql
commit 8f3d0d4b81e17a0aac0449ca10fafa679cb6deec
Author: Jonas Bernoulli <jonas@bernoul.li>
Commit: Jonas Bernoulli <jonas@bernoul.li>

    Use font-lock-flush and font-lock-ensure if available
    
    `font-lock-fontity-buffer' is only intended for interactive use.  Emacs
    v25.1 adds `font-lock-flush' and `font-lock-ensure' as replacements.  A
    lot of reading revealed that we actually have to call both functions.
