per maintainer update request by PR#44548.
Changes in pkgsrc:
* Added LICENSE.
Changes:
* Versions of ipa_{ac,db,st}_mod APIs were changed to 2.
* Optimized and simplified source code of IPA.
* New parameter "ictl" in ipa.conf.
* New parameter "ctl_query_max_size" in ipa.conf.
* New parameter "value_units" in ipa.conf and ipastat.conf.
* Now "restart" and "expire" parameters are optional in ipa.conf.
* Now "limit" and "threshold" parameters in ipa.conf can be
equal to zero.
* Now ipactl can create and delete dynamic rules.
* Now ipactl accepts commands "set limit ... counter ..."
and "set threshold ... counter ...".
* If a limit or a threshold uses "null" database and if it was
initialized, then next time during initialization (when some time
related problem occurred) imitate its old state from its current
state.
* Allow to use '_' characters in macro variables names.
* Added support for ipactl's messages credentials checking for NetBSD.
* Give limitation on the depth of included files (macro variable
INCLUDE_DEPTH_MAX with default value 100).
* configure.ac was optimized.
* All manual pages were reformatted to follow traditional
typographic style.
* Now all debug messages in ipa and ipastat are written with
the "DEBUG: " prefix.
* Check correctness of names of dynamic rules and names in
received control commands.
* Check correctness of names in ipa, ipastat and ipactl
options arguments.
* Now ipa does not use SIGALRM in timeout implementation for
control socket.
* Now ipactl does not use SIGALRM in timeout implementation.
* Now non-standard function mem_vasprintf() exported to modules
returns number of characters in allocated buffer.
* Now if some configuration error occurred in included file,
then ipa and ipastat log include history, that allows much
easy identify point of failure.
* Now ipactl does not have limits on lengths of rules, limits,
thresholds names.
* In some places where EWOULDBLOCK is checked, checks for EAGAIN
were added, as it is documented in SUSv3.
* On some systems there is no strtoull(3) function, which
is part of SUSv3, check it in the configure script and
use own version if it is absent.
