shared/specifier: provide proper error messages when specifiers fail to read files
ENOENT is easily confused with the file that we're working on not being

journal-file: port journal_file_open() to openat_report_new()
We so far had some magic logic in place that files we open for write
with size zero are freshly created. That of course is a bogus
assumption, in particular as this code deals with corrupted file systems
which oftentimes contain zero size inodes from left-over runs.
Let's fix this properly, and actually let the kernel tell us whether it
create the file or not.

basic/strv: avoid potential UB with references to array[-1]
"""
Given an array a[N] of N elements of type T:
- Forming a pointer &a[i] (or a + i) with 0 ≤ i ≤ N is safe.
- Forming a pointer &a[i] with i < 0 or i > N causes undefined behavior.
- Dereferencing a pointer &a[i] with 0 ≤ i < N is safe.
- Dereferencing a pointer &a[i] with i < 0 or i ≥ N causes undefined behavior.
"""
As pointed by by @medhefgo, here we were forming a pointer to a[-1]. a itself
wasn't NULL, so a > 0, and a-1 was also >= 0, and this didn't seem to cause any
problems. But it's better to be formally correct, especially if we move the
code to src/fundamental/ later on and compile it differently.
Compilation shows no size change (with -O0 -g) on build/systemd, so this should
have no effect whatsoever.
