Fix three clang warnings

Patch to silence three clang warnings:

dnslookup.c:476:1: warning: '/*' within block comment [-Wcomment]
  476 | /* End of routers/dnslookup.c */
      | ^
1 warning generated.

search.c:685:1: warning: unused label 'out' [-Wunused-label]
  685 | out:
      | ^~~~
1 warning generated.

In file included from tls.c:466:
./tls-gnu.c:1189:1: warning: non-void function does not return a value
[-Wreturn
-type]
 1189 | }
      | ^
1 warning generated.

The first is straightforward.
The second is not beautiful.
The last requires gnutls and I made an executive decision about the return
value.

I use
CC=/usr/bin/clang-19 -Wall -Wextra -Wno-constant-logical-operand
-Wno-dangling-else -Wno-format -Wno-format-extra-args
-Wno-format-insufficient-args -Wno-format-invalid-specifier
-Wno-misleading-indentation -Wno-missing-field-initializers -Wno-parentheses
-Wno-self-assign -Wno-sign-compare -Wno-unused-but-set-variable
-Wno-unused-function -Wno-unused-parameter -Wno-unused-variable
