    Include sysstdio.h instead of stdio.h, to avoid locking
    stdio streams in many cases.

    Simplify by using ordinary calls like putc to explicitly-unlocked
    calls like putc_unlocked, since the ordinary calls are now
    unlocked anyway.

    * src/pdumper.c (Fdump_emacs_portable):
    Coalesce adjacent printfs.
    * src/nsterm.h: Include sysstdio.h as this file’s macros rely on it.
    * src/regex-emacs.c (print_compiled_pattern):
    Omit redundant fflush.
    * src/sysstdio.h: Include unlocked-io.h.
