d3539be8f2 Remove stime() function calls
stime() has been deprecated in glibc 2.31 and replaced with
clock_settime(). Let's replace the stime() function calls with
clock_settime() in preperation.

6937487be7 libbb: reduce the overhead of single parameter bb_error_msg() calls
Back in 2007, commit 0c97c9d437 ("'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.

2aeb201c97 libbb: new option FEATURE_ETC_SERVICES: if off, /etc/services reads often avoided
In practice, "wget http://host.com/" always uses port 80.
People explicitly set non-standard ports via options or parameters
("telnet 1.2.3.4 567" or "telnet 1.2.3.4 ftp") instead of modifying
/etc/services.

67b23e6043 getopt_ulflags -> getopt32.
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

5c0ae06ef1 - No options should set the current system time.
Shaun Jackman writes:
A bug introduced in svn 11946 broke rdate. It no longer sets the
current system time when no options are specified. The options have
the opposite sense from what one might think, and, oddly enough, -ps
is intentionally a no-op.

Quoth rdate(8) from the BSD System Manager's Manual:

    -p      Do not set, just print the remote time
    -s      Do not print the time.

bb_lookup_port now takes 3 parameters but rdate has not been modified
accordingly and fails to compile in the current CVS version.
The modification below fixes the problem.

Now, RFC868 allows both UDP and TCP implementations of the time protocol
so this may not work if someone defines a udp time service other than 37
but who would do that?

ffccf6eb5d Change interface to bb_lookup_host, dont try and set port inside this
function as there is no gracefull way of handling failures.
Rename bb_getport to bb_lookup_port, allow a default port to be
specified so it always returns a correct value.
Modify ftpgetput/rdate/wget to use the new interface.
wget/rdate now use etc/services with a falback default value.

89f10bcf37 Patch from Fillod Stephane:
* The "rdate.patch" file makes rdate to NOT settimeofday if the date to be
set equals current date. This prevents the system from experiencing nasty time
discontinuities caused by sub-second changes, with a protocol that has only
over second resolution. Depending on your taste, the "fprintf(stderr..." may be
removed.

04d055f4e1 Fix rdate and ftpget/ftpput so they compile with the new xconnect.
I have checked rdate.  Someone should also check ftpget/ftpput to
be sure they still work.

e6dc439b3a Rework wget, the xconnect interface, and its various clients
in order to fix the problems with round robin DNS reported
by Andrew Flegg:
    http://busybox.net/lists/busybox/2003-October/009579.html

This removes the ipv6 specific xconnect dns lookups.  I do
not see why that would need to be special cased for ipv6 as
was done, but that will just have to be tested.

So IPV6 people -- please test this change!

0b31586c71 A patch from Bart Visscher <magick@linux-fan.com> to add an
xconnect helper routine which does:
        -address and port resolving
	-tries to connect to all resolved addresses until connected
	-uses getaddrinfo, so works for IPv6 too
This patch also ports rdate, telnet, and wget to use the new
xconnect function.  Thanks Bart!
