Sync with upstream profanity-im/profanity.

Major upstream changes incorporated:

Memory management
  - Replace malloc+memset with g_new0 throughout codebase
  - Adopt auto_gchar / auto_gcharv / auto_gerror / auto_jid cleanup macros
  - Replace free() with g_free() for GAlloc'd memory

Editor rewrite
  - Remove pthread-based async editor; use GChildWatch callback API
  - New launch_editor(initial_content, callback, user_data) interface
  - Proper signal handling (SIGINT, SIGTSTP, SIGPIPE reset in child)
  - ui_suspend()/ui_resume() integration for TTY management

OMEMO improvements
  - Dual backend support: libsignal-protocol-c and libomemo-c
  - Proper pre-key removal after use (XEP-0384 compliance)
  - Automatic pre-key regeneration when store drops below threshold
  - New functions: omemo_is_device_active(), omemo_is_jid_trusted()
  - omemo_get_jid_untrusted_fingerprints() for better error messages
  - Fingerprint notifications on new device identity discovery
  - Deterministic pre-key ID generation tracking max_pre_key_id
  - omemo_trust_changed() UI updates on trust state changes

JID validation
  - RFC 6122-compliant validation in jid_is_valid()
  - Character-level checks (RFC 6122 forbidden chars: & ' / : < > @)
  - Length limits: 1023 per component, 3071 total
  - New jid_is_valid_user_jid() for user vs. service JID distinction

Database
  - Schema migration v3: UNIQUE constraint on archive_id for deduplication
  - Triggers for corrected message tracking (replaces_db_id / replaced_by_db_id)
  - db_history_result_t return type, _truncate_datetime_suffix()

UI / console
  - win_warn_needed() / win_warn_sent() warning deduplication hash table
  - PAD_MIN_HEIGHT dynamic pad sizing with PAD_THRESHOLD auto-cleanup
  - Spellcheck integration in input field with Unicode word detection
  - cons_spellcheck_setting() for /settings ui output
  - /[command]? shortcut for command help

Account config
  - Account name sanitization for GKeyFile special chars ([ ] = # \n \r)
  - Replace popen() with g_spawn_sync() for eval_password
  - TLS policy: add "direct" option alongside legacy

Connection
  - Port validation with g_assert (0–65535)
  - SHA-256 certificate fingerprint support (XMPP_CERT_PUBKEY_FINGERPRINT_SHA256)
  - "direct" TLS policy alias for legacy SSL

Common utilities
  - str_xml_sanitize() for XML 1.0 illegal character removal
  - string_matches_one_of() with formatted error messages
  - valid_tls_policy_option() helper
  - prof_date_time_format_iso8601() utility
  - Improved strip_arg_quotes() with backslash unescaping
  - prof_occurrences() uses g_slist_prepend + reverse for performance

PGP / OX
  - Proper GPGME resource cleanup with goto-cleanup pattern
  - g_string_free(xmppuri) leak fix in _ox_key_lookup

CSV export
  - Use GString + g_file_set_contents instead of raw write() syscalls

Tests
  - Restructured into subdirectories: command/, config/, xmpp/, ui/, omemo/, otr/, pgp/
  - New test_cmd_ac.c for autocompleter unit tests
  - Updated stubs for new UI suspend/resume functions

License headers
  - Migrate to SPDX-3.0 identifiers (GPL-3.0-or-later WITH OpenSSL-exception)

────────────────────────────────────────────────────
cproof-specific preservations:

  - XEP-0308 LMC: replace_id ?: id logic in message/stanza/omemo
  - Force encryption: cmd_force_encryption, test_forced_encryption
  - CWE-134: format string protection (cons_show("%s", ...))
  - y_start_pos-based paging in window.c
  - db_history_result_t return type, _truncate_datetime_suffix()

Merge-time fixes:

  - common.c: format-security (-Werror) — cons_show(errmsg) → cons_show("%s", errmsg)
  - database.c: null-deref guard — !msg->timestamp → msg && !msg->timestamp
  - console.c: implicit size_t → int cast — (int)(maxlen + 1)
  - tlscerts.c: %d for size_t — %zu

Build system:
  - Kept autotools (Makefile.am, configure.ac); upstream uses Meson
  - Restored deleted files: bootstrap.sh, autogen.sh, ax_valgrind_check.m4, configure-debug
  - Updated Makefile.am test paths for subdirectory structure
  - Added test_cmd_ac, test_forced_encryption to test sources

Functional tests:
  - Use cproof version; upstream requires stbbr_for_xmlns from updated stabber
  - Not yet available in devs/stabber fork

Closes #64

c5a131ee46 Introduce our own shutdown callback mechanism. 
Instead of adding stuff to `_shutdown()`, we can now register a shutdown
routine from the respective `init()` function of our modules.

This also has the advantage, that we're sure they're called in reverse
order from how the initialization happened.

I didn't simply use `atexit()` because POSIX says that the number of
possible callbacks is limited (min 32) and I was not sure whether
we will maybe extend this number at one point.

fdfe3e2ad9 Rework OMEMO handling on disconnect 
* Fix missing destruction of `session_store` and mutex
* Replace `glib_hash_table_free()`
  The glib API `g_hash_table_destroy()` does exactly the same.
* Use the default libsignal `destroy_func` instead of doing that manually
* Set internal state to `0` after everything is cleaned up

199162b11a Add omemo_close function 
We call omemo_init() when starting profanity and should have an
omemo_close() at exit.

For now we free the fingerprint autocompleter in there.
