c1f46b8fcb libc: iconv: push option ignore into citrus_iconv_open()
Make it vaguely aware of options in the sense that it now knows that it
can zap any trailing //.  It now copies the entire string in realsrc and
realdst, then terminates them at the options.

__bsd___iconv_open can now stop trying to allocate memory just for this
purpose, and the new version is technically more correct.  GNU libiconv
will ignore options on the `in` codeset and still do the right thing.

d915a14ef0 libc: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

079171874c iconvctl(3): remove superfluous NULL pointer tests
convname and dst are guaranteed to be non-NULL by iconv_open(3).
src is an array. Remove these tests for NULL pointers.
While I'm here, eliminate a strlcpy with a correct but suspicious-looking
calculation for the third parameter (i.e. not a simple sizeof).
Compare the strings in-place instead of copying.

d8a7885b36 Fix several memory leaks, and crashes, in iconvlist(3).
- Both curitem and curitem (via the names list) was always leaked.
- malloc(3) failures lead to some leaks.
- __bsd___iconv_get_list() failure lead to a crash since its error was not
  handles and __bsd___iconv_free_list() is not NULL-safe.

I have slightly refactored this to avoid extra malloc and free logic in cases
of malloc(3) failing.

There are still bad assumptions here that I did not deal with.  One of which is
that the data will always have a '/' so the strchr(3) will not return NULL.

db2af39373 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.
