cf4a868be5 debug: Remove "override_logfile"
The only writer to this variable left with c377845d27. The
closest match for override_logfile is is_default_dyn_LOGFILEBASE()

1ea1816629 util/iconv: reject improperly packed UTF-8
If we allow a string that encodes say '\0' as a multi-byte sequence,
we are open to confusion where we mix NUL terminated strings with

50047588c0 torture: talloc_string_sub tests for utf-8 brevity
If we allow overly long UTF-8 sequences (in the tests, encoding '\0'
as 2, 3, or 4 bytes), it might be possible for bad strings to slip
through.

We fail. But wait for the next commit.

2b9a1feae7 lib:util: Fix return value of tdb_fetch_uint32_byblob()
The initialize_winbindd_cache() function uses tdb_fetch_uint32_byblob()
to check if the cache version is valid and up to date. As
tdb_fetch_uint32_byblob() returns false for a successful fetch, we
always remove the winbind cache database. This breaks the winbind
offline logon feature.

This also affects other caches and pdb.

05a1ca2f4c util: Ensure debugger can be attached to process
samba_start_debugger() attempts to start a debugger attached to the
calling process by calling system() to start a background process.
However, if the spawned shell exits before the debugger has had a chance
to attach, the debugger process will no longer be a child of the parent
process (as it will have been reparented).

If the system does not allow tracing by non-child processes, attachment
may fail as a result.

This commit replaces the system() call and the implicit shell around
xterm with an explicit fork()/exec() so that the debugger remains a
child of the calling process, ensuring the attachment succeeds unless
tracing is disabled completely.
