r258537 (hrs):
Add ICONV_{GET,SET}_ILSEQ_INVALID iconvctl. GNU iconv returns
EILSEQ when there is an invalid character in the output codeset
while it is valid in the input. However, POSIX requires iconv()
to perform an implementation-defined conversion on the character.
So, Citrus iconv converts such a character to a special character
which means it is invalid in the output codeset.
This is not a problem in most cases but some software like libxml2
depends on GNU's behavior to determine if a character is output
as-is or another form such as a character entity (&#NNN;).
r258587 (peter):
Move the iconv wrapper source from libc_nonshared to libc/iconv so
that it is all in the one place again. Rename libc/iconv/iconv.c
to bsd_iconv.c. Compile the wrappers into libc.a so that
WITHOUT_DYNAMICROOT works again.

r257583 (peter):
Remove the WITH_LIBICONV_COMPAT hack that seems to do more harm
than good. This caused libc to spoof the ports libiconv namespace
and provide a colliding libiconv.so.3 to fool rtld. This should
have been removed some time ago.
r258012:
Remove WITH_LIBICONV_COMPAT file to chase after r257583.
r258013:
Regenerate src.conf.5 after removal of WITH_LIBICONV_COMPAT.

extensions and also tried to be link time compatible with ports libiconv.
This splits that functionality and enables the parts that shouldn't
interfere with the port by default.
WITH_ICONV (now on by default) - adds iconv.h, iconv_open(3) etc.
WITH_LIBICONV_COMPAT (off by default) adds the libiconv_open etc API, linker
symbols and even a stub libiconv.so.3 that are good enough to be able
to 'pkg delete -f libiconv' on a running system and reasonably expect it
to work.
I have tortured many machines over the last few days to try and reduce
the possibilities of foot-shooting as much as I can. I've successfully
recompiled to enable and disable the libiconv_compat modes, ports that use
libiconv alongside system iconv etc. If you don't enable the
WITH_LIBICONV_COMPAT switch, they don't share symbol space.
This is an extension of behavior on other system. iconv(3) is a standard
libc interface and libiconv port expects to be able to run alongside it on
systems that have it.
Bumped osreldate.
a macro with parameters. Remove a __DECONST hack and add consts instead
for gnu libiconv API compatability. This makes it work with things like
devel/boost-libs that expects to use "iconv" as though it were a pointer.
setting. It can be built by setting the WITH_ICONV knob. While this
knob is unset, the library part, the binaries, the header file and
the metadata files will not be built or installed so it makes no impact
on the system if left turned off.
This work is based on the iconv implementation in NetBSD but a great
number of improvements and feature additions have been included:
- Some utilities have been added. There is a conversion table generator,
which can compare conversion tables to reference data generated by
GNU libiconv. This helps ensuring conversion compatibility.
- UTF-16 surrogate support and some endianness issues have been fixed.
- The rather chaotic Makefiles to build metadata have been refactored
and cleaned up, now it is easy to read and it is also easier to add
support for new encodings.
- A bunch of new encodings and encoding aliases have been added.
- Support for 1->2, 1->3 and 1->4 mappings, which is needed for
transliterating with flying accents as GNU does, like "u.
- Lots of warnings have been fixed, the major part of the code is
now WARNS=6 clean.
- New section 1 and section 5 manual pages have been added.
- Some GNU-specific calls have been implemented:
iconvlist(), iconvctl(), iconv_canonicalize(), iconv_open_into()
- Support for GNU's //IGNORE suffix has been added.
- The "-" argument for stdin is now recognized in iconv(1) as per POSIX.
- The Big5 conversion module has been fixed.
- The iconv.h header files is supposed to be compatible with the
GNU version, i.e. sources should build with base iconv.h and
GNU libiconv. It also includes a macro magic to deal with the
char ** and const char ** incompatibility.
- GNU compatibility: "" or "char" means the current local
encoding in use
- Various cleanups and style(9) fixes.
