[Bug manual/2963] New: const in iconv arg 2

[gin at mo dot msk dot ru]

Versions: all known, from 2.2.4 to 2.4.  This is why leaving version
unspecified.

`iconv' arg 2 is documented and declared in `iconv.h' to be `char
**__restrict'.

<http://www.opengroup.org/onlinepubs/007908799/xsh/iconv.html>
specifies it to be `const char **'.  So do
<http://www.opengroup.org/products/publications/catalog/u055.htm>.

Those specifications may be wrong in some way, and there may be strong
reasons to leave the interface as it is.  But <(libc) Generic
Conversion Interface> neither states that specifications are
considered wrong in this way nor explains why the interface being
described should remain as it is.

<(libc) Generic Charset Conversion>, and many other <(libc)> sections,
do include even <comparisons with other implementations>, not
considering this improper.  Design considerations wrt standard
conformance are at least just as proper there.

The reasons / considerations lacking in manual are not trivial:

Subject: 

`libc/manual/charset.texi' was not changed since Tue Jul 22 20:05:55
2003 UTC, and still refers to XPG2, suggesting that everything is the
same since.  In fact, there were new open group standard issues after
XPG2, that changed `iconv' prototype, and `iconv' implementation and
documentation conforms to the newest standard versions as in
<http://www.opengroup.org/onlinepubs/009695399/functions/iconv.html>,
not to old ones.
