add manpage for iconv(1).

Citrus iconv support(4)
add iconv external I/F (iconv.h - iconv_open()/iconv()/iconv_close()) and
iconv(1) utility.
TODO:
- bump libc minor.
- add iconv data files.
- create manpages: iconv_open(3)/iconv(3)/iconv_close(3)/iconv(1)/
mkesdb(1)/mkcsmapper(1).

Support -o outfile like gnu does and check writes for failure.

conform -> conforms - this is the file that was supposed to be changed.
apb@ was right about iconv(3).

fix typo, from Ryo HAYASAKA in PR 44332.

allow SUSv3 syntax.
if from/to code is ommitted, auto-guess'ed from current locale.

branches: 1.2.24; 1.2.30;
Grammar and mdoc improvements. Sort sections. Only mention iconv(3)
in SEE ALSO, since iconv_open(3) and iconv_close(3) are the same.

add manpage for iconv(1).

Support -o outfile like gnu does and check writes for failure.

Switch the iconv(3) prototype to the POSIX conformant variation

Remove const from the 2nd argument.

const char ** and char ** are incompatible types and it was a cost to keep
the technically incompatible form for a more purist variation. NetBSD was
almost the last alive OS to still keep the const argument (known leftovers:
Minix and Illumos).

Keep the const form for the internal purposes inside citrus and rump.

Address the build breakage fallout in the same change.

There are no ABI changes.

Change accepted by core@.

Save errno around fwrite(), which can otherwise trash it; PR 47813.
This appears to fully resolve the problem described in the PR, even
though one might think it wouldn't.

Use __dead

Fix error message when input file does not exist. From James Lowden.

sort iconv -l output

count number of invalid characters correctly.
ok'ed by tshiozak@.

Be more verbose in error message if iconv_open fails.

correct how to show size_t. %d -> %lu and cast to unsigned long.
