dname_dec: now iterates over the packet only once.
convert_dname: remove redundant checks and code shrink.
While testing I've noticed that some of the tests didn't compile
properly, so I fixed them.

Commit d1b75e184 (httpd: permit non-default home directory with NOMMU
enabled) only works when used with the '-f' (foreground) option.
When '-f' isn't specified and NOMMU is enabled bb_daemonize_or_rexec()
is called to daemonize the server. Since the server process has been
re-execed the previous patch results in the xchdir() not being called.
Fix this by resetting the re_execed variable in this case.

When ENABLE_FEATURE_WGET_OPENSSL is enabled, correctly implement TLS
verification by default. And only ignore verification errors, if
--no-check-certificate was passed.
Also note, that previously OPENSSL implementation did not implement
TLS verification, nor printed any warning messages that verification
was not performed.

When BusyBox is compiled with NOMMU enabled running httpd with
the '-h' option fails even if the specified directory exists:
$ ls -d www
www
$ busybox httpd -fvvvp 8080 -h www
...
... try to access http://localhost:8080/www
...
httpd: can't change directory to 'www': No such file or directory
The parent process executes xchdir("www"). When a connection is accepted
it's handled by re-executing httpd in inetd mode. The child process
inherits the current directory "www" and tries to change directory again
to "www", which fails.
Omit the call to xchdir() when httpd is re-executed.

Review of real-world results of the above shows that with small
initial offsets, freq correction can be allowed to kick in sooner,
whereas with large (~0.8s) offsets, we still start freq correction
a bit too soon.
Let's rebalance this a bit.

Under some circumstances, a DNS reply might contain no resource records,
e.g. when a valid domain is queried that does not have records of the
requested type.
Example with nslookup from BIND dnsutils:
$ nslookup -q=SRV example.org
Server: 10.11.12.13
Address: 10.11.12.13#53
Non-authoritative answer:
*** Can't find example.org: No answer
Currently the busybox nslookup applet simply prints nothing after the
"Non-authoritative answer:" line in the same situation.
This change modifies nslookup to either print "Parse error" or "No answer"
diagnostics, depending on the parse_reply() return value.

Back in 2007, commit 0c97c9d43707 ("'simple' error message functions by
Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower
overhead call to bb_perror_msg() when only a string was being printed
with no parameters. This saves space for some CPU architectures because
it avoids the overhead of a call to a variadic function. However there
has never been a simple version of bb_error_msg(), and since 2007 many
new calls to bb_perror_msg() have been added that only take a single
parameter and so could have been using bb_simple_perror_message().
This changeset introduces 'simple' versions of bb_info_msg(),
bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and
bb_herror_msg_and_die(), and replaces all calls that only take a
single parameter, or use something like ("%s", arg), with calls to the
corresponding 'simple' version.
Since it is likely that single parameter calls to the variadic functions
may be accidentally reintroduced in the future a new debugging config
option WARN_SIMPLE_MSG has been introduced. This uses some macro magic
which will cause any such calls to generate a warning, but this is
turned off by default to avoid use of the unpleasant macros in normal
circumstances.
This is a large changeset due to the number of calls that have been
replaced. The only files that contain changes other than simple
substitution of function calls are libbb.h, libbb/herror_msg.c,
libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c,
networking/udhcp/common.h and util-linux/mdev.c additonal macros have
been added for logging so that single parameter and multiple parameter
logging variants exist.
The amount of space saved varies considerably by architecture, and was
found to be as follows (for 'defconfig' using GCC 7.4):
Arm: -92 bytes
MIPS: -52 bytes
PPC: -1836 bytes
x86_64: -938 bytes
Note that for the MIPS architecture only an exception had to be made
disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h)
because it made these files larger on MIPS.
