We expect these macros to generate tautological compares
intentionally, so disabling the warning is just fine.

2082c0c3b5 lib/util: Avoid splitting tevent-unix-util as public library
BUG: https://bugzilla.samba.org/show_bug.cgi?id=11946

Commit 670db6ac1d split tevent-util public
library to create tevent-unix-util public library for standalone ctdb
use.  This created a public library dependency between samba and ctdb
for packaging.

Bundle tevent_unix.c in public library tevent-util as before.  However,
to avoid the dependencies for packaging, standalone ctdb build will
build tevent-util as a private library with only tevent_unix.c

This simplifies any new subsystems (or libraries) which need tevent-util
and are linked in both samba and ctdb.

88be24c279 util/attr.h: use HAVE___ATTRIBUTE__, not __GNUC__ comparisons
The comparisons that look like

    #if (__GNUC__ >= 3) && (__GNUC_MINOR__ >= 1 )

fail if __GNUC_MINOR__ is 0.  The intended comparison is something
more like

    #if __GNUC__ > 3 || (__GNUC__ == 3 && __GNUC_MINOR__ >= 1)

However, given that:

 * these checks are really trying to test the presence of
   __attribute__,

 * there are now credible compilers that are not GCC, which have
   __attribute__ but might not be good at emulating __GNUC__
   numbers, and

 * we really face little risk of running into GCC 2.95

 * we have a HAVE___ATTRIBUTE__ check in ./configure

let's not do the version comparisons.

(Untested on GCC 2.95, GCC 3.0 and GCC 3.1).

5235f1facf util/binsearch: macro for greater than or equal search
Sometimes you want to find the place where an item would be in a
sorted list, whether or not it is actually there.

The BINARY_ARRAY_SEARCH_GTE macro takes an extra 'next' pointer
argument over the other binsearch macros. This will end up pointing to
the next element in the case where there is not an exact match, or
NULL when there is. That is, searching the list

     { 2, 3, 4, 4, 9}

with a standard integer compare should give the following results:

search term    *result    *next
         1      -          2
         3      3          -
         4      4 [1]      -
         7      -          9
         9      9          -
        10      -          - [2]

Notes
[1] There are two fours, but you will always get the first one.
[2] The both NULL case means the search term is beyond the last list
item.

You can safely use the same pointer for both 'result' and 'next', if
you don't care to distinguish between the 'greater-than' and 'equals'
cases.

There is a torture test for this.

The intention of strv_addn() is to be able to add some number of

assumes that the old _strv_append() added the trailing NUL to form a
valid strv.  That's not true.
