clang complains that lm_resp and nt_resp is used uninitialized. This
is true for the "goto done;" in line 2644. This directly calls
log_authentication without having initialized those two blobs.

Previously the private context was caching a pointer to
a string returned from lp_XXX(). This string can change
on config file reload. Ensure the string is talloc_strup'ed
onto the owning context instead.

When winbindd is asked to map a name like realm.com\name to a SID ,that
is sucessfully resolved through the lsa lookup name call. The same call
also returns the short domain name (netbios name of the domain). Use
that short domain name for the sid_to_name cache entry, so that
subsequent sid_to_name queries return the expected netbiosname\name
result and not realm.com\name.

In order to detect an value overflow error during
the string to integer conversion with strtoul/strtoull,
the errno variable must be set to zero before the execution and
checked after the conversion is performed. This is achieved by
using the wrapper function strtoul_err and strtoull_err.

Why? This makes the negative mapping condition (is_null_sid) more
explicit in the code.
The callers in lookup_sid initialized "psid" anyway before, and the ones
in wb_xids2sids now do as well. This is more in line with other APIs we
have: Only touch output parameters if you have something to say.

This is needed in preparation of moving the step to update the idmap
cache from the per-idmap-domain callback wb_xids2sids_dom_done() to the
top-level callback wb_xids2sids_done().
Currently the sequence of action is:
* check cache, if not found:
* ask backends
* cache result from backend
* return results
Iow, if we got something from the cache, we don't write the cache.
The next commit defers updating the cache to the top-level callback, so
the sequence becomes
* check cache, if not found:
* ask backends
* cache results
* return results
This has two problems:
* it needlessly writes to the cache what we just got from it
* it possibly overwrites the ID_TYPE_BOTH for a SID-to-xid mapping in
the following case:
- existing ID_TYPE_BOTH mapping in the cache, eg:
IDMAP/SID2XID/S-1-5-21-2180672342-2513613279-2566592647-512 -> Value: 3000000:B
- someone calls wb_xids2sids_send() with xid.id=3000000,xid.type=ID_TYPE_GID
- cache lookup with idmap_cache_find_gid2sid() succeeds
- when caching results we'd call idmap_cache_set_sid2unixid() with the
callers xid.type=ID_TYPE_GID, so idmap_cache_set_sid2unixid() will
overwrite the SID-to-xid mapping with ID_TYPE_GID

This is in preparation of setting the result of the mapping in the top-
level callback wb_xids2sids_done(), not in the per-idmap-domain callback
wb_xids2sids_dom_done().
When caching the mapping we need the id-type from the backend, so we
need a way to pass up that information from wb_xids2sids_dom_done() up
to wb_xids2sids_done()
The xids array copy gets passed from wb_xids2sids_send() to
wb_xids2sids_dom_send(), so wb_xids2sids_dom_done() can then directly
update the top-level copy.
