With Clang 10.0.0 on FreeBSD 11.4, compiling lib/dns/spnego.c triggers
the following warnings:

Address by replacing all instances of the GSS_S_DEFECTIVE_TOKEN constant
with a boolean value. Invert the values returned by cmp_gss_type() so
that its only call site reads more naturally in the context of the
comment preceding it.

The three functions has been modeled after the arc4random family of
functions, and they will always return random bytes.
The isc_random family of functions internally use these CSPRNG (if available):
1. getrandom() libc call (might be available on Linux and Solaris)
2. SYS_getrandom syscall (might be available on Linux, detected at runtime)
3. arc4random(), arc4random_buf() and arc4random_uniform() (available on BSDs and Mac OS X)
4. crypto library function:
4a. RAND_bytes in case OpenSSL
4b. pkcs_C_GenerateRandom() in case PKCS#11 library
4183. [cleanup] Use timing-safe memory comparisons in cryptographic
code. Also, the timing-safe comparison functions have
been renamed to avoid possible confusion with
memcmp(). [RT #40148]

2988. [experimental] Added a "dlopen" DLZ driver, allowing the creation
of external DLZ drivers that can be loaded as
shared objects at runtime rather than linked with
named. Currently this is switched on via a
compile-time option, "configure --with-dlz-dlopen".
Note: the syntax for configuring DLZ zones
is likely to be refined in future releases.

2987. [func] Improve ease of configuring TKEY/GSS updates by
adding a "tkey-gssapi-keytab" option. If set,
updates will be allowed with any key matching
a principal in the specified keytab file.
"tkey-gssapi-credential" is no longer required
and is expected to be deprecated. (Contributed
