lib:charset: Remove use of talloc_autofree_context() for global_iconv_handle
All other callers use NULL here anyway, so there's no
need to use a special context for get_iconv_handle().

commit 2a4d07b999df2343c694a2b373d3b506bd3d5682
Author: Jeremy Allison <jra at samba.org>
Date: Tue Apr 11 15:57:28 2017 -0700
lib: param: Remove the last external use of global_iconv_handle by calling the utility function reinit_iconv_handle().
Add an error check.
This *looks* like a logic change, but it is not.
The only change is the addition of the error return check.
The reason is that the changed function, reload_charcnv(),
is the *only* function that sets lp_ctx->iconv_handle. And
it does so just before setting global_iconv_handle = lp_ctx->iconv_handle.
Calling the utility function reinit_iconv_handle()
instead merely sets global_iconv_handle first, then
assigns it (as the return) to lp_ctx->iconv_handle.
So all this is doing is reversing the order of
setting global_iconv_handle and lp_ctx->iconv_handle
to the same thing.
Even the removal of the lines:
- struct smb_iconv_handle *old_ic = lp_ctx->iconv_handle
- if (old_ic == NULL) {
- old_ic = global_iconv_handle;
has no effect, as remember that lp_ctx->iconv_handle
is only ever set to the same value as global_iconv_handle,
and once this function has been run once, lp_ctx->iconv_handle != NULL.
This allows us finally to make global_iconv_handle private
to the C source file that defines it.

lib: Remove smb_iconv_handle_reinit_lp()
It's merely a wrapper for smb_iconv_handle_reinit(),
only used in one place and smb_iconv_handle_reinit()
is already called from lib/param/loadparm.c.
Removing this will make it easier to make global_iconv_handle
private state to lib/util/charset/codepoints.c later.
