ci: fix CodeQL build failure due to missing po4a dependency
Replace the autobuild action with a custom build step that
disables document translation. The autobuild auto-installed
po4a but the environment lacks the Unicode::GCString Perl
module, causing the translation step to fail. CodeQL analysis
does not need translated man pages.
dmesg: fix out-of-bounds read when parsing malformed kmsg file
Add bounds check to LAST_KMSG_FIELD macro to prevent accessing
memory before the buffer start, and null-terminate the record
buffer in print_kmsg_file() to stop string functions from reading
past the valid data.
Commit ac0147f added '+' to the getopt(3) option string which
allowed the passing of all arguments after a non-option arg
to be passed to the invoked shell, in this case after <user>.
However, this introduced a regression in runuser(1) and su(1)
where options for both utilities are scattered before and after
the username. E.g.: "su <user> -c 'echo foo' -s /bin/bash" will
pass both -c and -s argument sets to the invoked shell instead
of simply passing -c 'echo foo'.
Note that this behavior is more common in BSD/macOS-style
implementations of su(1), in a future commit this behavior will
be added more sensibly and carefully.

lastlog2: add --journal option to manage SQLite journal mode
Add -j/--journal option to the lastlog2 command to allow users to
view and set the SQLite journal mode. Without an argument, it displays
the current mode. With an argument, it sets the mode to the specified
value (WAL, DELETE, TRUNCATE, PERSIST, MEMORY, OFF).
The option supports flexible argument formats:
- Short option with space: -j WAL
- Short option without space: -jWAL
- Long option with equals: --journal=WAL
Also update bash-completion to provide journal mode suggestions and
add documentation to the man page with usage examples.
Add ll2_set_journal_mode() and ll2_get_journal_mode() functions to
allow setting and querying SQLite journal modes. This enables users
to switch to WAL (Write-Ahead Logging) mode for better concurrency
in high-traffic scenarios.
WAL mode allows readers and writers to operate concurrently without
blocking each other, significantly reducing database lock contention
in environments with frequent SSH logins.
The journal mode setting is persistent and only needs to be set once
per database.

available and off_t is signed, keep it at that.
In theory, this might fix very intelligent static analysers which notice
that off_t is long int but %ll expects long long, but in reality, this
fixes 32 bit off_t builds. Without this, wrong addresses are shown.
