d45dee7c00 chase-symlinks: don't insist on absolute paths if CHASE_PREFIX_ROOT is set 
There's little reason to require this, given that we can just say that
if a relative path is specified it is to be read relative to the root.

This fixes a bootctl bug introduced by
3730dc5d5b which didn't bother prefixing
paths as necessary.

ee3455cf11 fd-util: rename CLOSE_AND_REPLACE() -> close_and_replace() 
We have free_and_replace() and friends, they are all named with lower
letters, even they are macros, not functions.
For consistency, let's rename CLOSE_AND_REPLACE() with lower letters.

This also mekes the macro used more places.

lot.

782c6e5c90 time-util: fix overflow condition in usec_sub_signed() 
If the delta specified is INT64_MIN, and we negate that we'd end up at
INT64_MAX+1 which is outside of the int64_t type. Hence let's treat this
case specifically to avoid unintended overflows.

36bac2dcba basic/user-util: avoid filesystem access check 
The check of u==UID_NOBODY is just a register comparison, but
synthesize_nobody() requires a system call, so let's invert the order in the
condition. Since most calls into this module are not for nobody, we should
save one syscall in the common case.

8a7adccbdb various: try to use DEFAULT_USER_SHELL for root too 
/bin/sh as a shell is punishing. There is no good reason to make
the occasional root login unpleasant.

Since /bin/sh is usually /bin/bash in compat mode, i.e. if one is
available, the other will be too, /bin/bash is almost as good as a default.
But to avoid a regression in the situation where /bin/bash (or
DEFAULT_USER_SHELL) is not installed, we check with access() and fall back
to /bin/sh. This should make this change in behaviour less risky.

(FWIW, e.g. Fedora/RHEL use /bin/bash as default for root.)

This is a follow-up of sorts for 53350c7bba,
which added the default-user-shell option, but most likely with the idea
of using /bin/bash less ;)

Fixes #24369.
