* src/fns.c (Fmember, Fassoc, Frassoc): Delegate to the cheaper Fmemq,
Fassq and Frassq for arguments of the appropriate types.
(eq_comparable_value): New function.

b87fc938a0 ; * src/xdisp.c (pos_visible_p): Yet another minor fix for...

* src/xdisp.c (decode_mode_spec): Don't use W->start if it is
outside of the buffer's accessible region.  (Bug#42220)

* src/json.c (lisp_to_json_toplevel_1, Fjson_parse_string): Check
whether input strings are actually strings.

* src/gnutls.c (gnutls_rnd) [WINDOWSNT]: Don't define a function
pointer, and don't load it from GnuTLS DLL.
(w32_gnutls_rnd) [WINDOWSNT]: Delete unused function.
* src/fns.c (gnutls_rnd) [WINDOWSNT]: Don't redirect to
w32_gnutls_rnd.

OpenBSD has pthread_set_name_np; FreeBSD appears to have both
this call and pthread_setname_np (the latter call is used in preference).

* configure.ac: Detect pthread_set_name_np.
* sys/systhread.c:
Include <pthread_np.h> and call pthread_set_name_np if available.

* admin/merge-gnulib (GNULIB_MODULES): Add getrandom.
* doc/lispref/text.texi (Format of GnuTLS Cryptography Inputs):
Don’t say that iv-auto uses GNUTLS_RND_NONCE.  Also, don’t say
that it returns the IV’s actual value, as it never has done that.
* src/fns.c, src/sysdep.c: Include sys/random.h, for getrandom.
* src/fns.c (Fsecure_hash_algorithms): Use getrandom so that this
function does not depend on HAVE_GNUTLS3.
* src/sysdep.c: Do not include <gnutls/crypto.h>.
(random_seed) [HAVE_LRAND48]: Can be long int now.
(init_random) [!WINDOWSNT]: Use getrandom syscall instead
of opening /dev/urandom, as this works even on GNU/Linux
hosts that lack /dev/urandom.  Don’t bother with gnutls_rnd
as it’s not needed now that we have getrandom.
