addc3e302d tmpfiles: don't follow unsafe transitions in path_set_*()
Since all path_set_*() helpers don't follow symlinks, it's possible to use
chase_symlinks(CHASE_NOFOLLOW) flag to both open the files specified by the
passed paths and check their validity (unlike their counterpart fd_set_*()
helpers).

1f56e4ce77 fs-util: add new CHASE_NOFOLLOW flag to chase_symlinks()
This flag mimics what "O_NOFOLLOW|O_PATH" does for open(2) that is
chase_symlinks() will not resolve the final pathname component if it's a
symlink and instead will return a file descriptor referring to the symlink
itself.

Note: if CHASE_SAFE is also passed, no safety checking is performed on the
transition done if the symlink would have been followed.

5ec9d06512 tmpfiles: introduce truncate_file() which deals with 'F' exclusively
TRUNCATE_FILE is now handled by a new dedicated function
truncate_file(). Indeed we have to take special care when truncating existing
file since the behavior is only specified for regular files.

Well that's not entirely true for fifo and terminal devices since O_TRUNC is
ignored in this case but even in for these types of file, truncating is
probably not the right thing to do.

It is worth noting that both truncate_file() and create_file() have been
modified so they use fstat(2) instead of stat(2) since both functions are not
supposed to follow symlinks.

31c84ff11e tmpfiles: introduce create_file() which deals with 'f'/'F' exclusively
write_one_file() only deals with the 'w' command and 'f'/'F' are now handled by
a new function create_file().

This is primarly done because 'w' is allowed to operate on any kind of files,
not just regular ones.

14f3480af1 tmpfiles: stat file in item_do() rather than in its callers
This a slight simplification since all callers of item_do()
(glob_item_recursively() and item_do() itself) stat the file descriptor only
for passing it to item_do().

b127bc99d1 sd-resolve: workaround for structured initialization to nested structs
When a nested struct is initialized by structured initializer, then
padding space is not cleared by zero. So, before setting values,
this makes explicitly set zero including padding.

This fixes the following false positive warning by valgrind:
```
==492== Syscall param sendmsg(msg.msg_iov[0]) points to uninitialised byte(s)

04c4d9199e resolved: TCP Fast Open and TLS Session Tickets for OpenSSL
To decreae latency this add support for TFO and TLS Session Tickets. As OpenSSL wouldn't let you easily set a different function all written data is temporarily cached and therefore needs to be flushed after each SSL function which can write data.

096cbdce13 resolved: basic OpenSSL support for DNS-over-TLS
This provides basic OpenSSL support without optimizations like TCP Fast Open and TLS Session Tickets.
Notice only a single SSL library can be enabled at a time and therefore journald functions provided by GnuTLS will be disabled when using OpenSSL.
Fixes #9531

ba6aaf5727 resolved: set io events after receiving EAGAIN for TLS
During handshake and TLS session closing, messages needs to be exchanged. Therefore this patch overrides the requested IO events for the TCP stream when the TLS is waiting for sending or receiving of messages during theses periods. This fixes issues with correctly closing the TLS stream and prevents the handshake from hanging in rare cases (not seen yet).

48c20af38e test: Increase qemu timeout from 90s to 180s
The usage of an initrd made TEST-09-ISSUE-2691 more likely to fail with
a timeout, so increase the timeout by 90s and adjust TimeoutStopSec=
accordingly.
