Let's not leak details from src/shared and src/libsystemd into
src/basic, even though you can't actually do anything useful with
just forward declarations from src/shared.
The sd-forward.h header is put in src/libsystemd/sd-common as we
don't have a directory for shared internal headers for libsystemd
yet.
Let's also rename forward.h to basic-forward.h to keep things
self-explanatory.
As a wrapper for `find_line_startswith`, `find_line_after` search for
the exact line and return the pointer for the next line, or NULL if
missing.
`find_line` with search for the exact line and return the pointer to the
beginning of the line.

Now that the necessary functions from log.h have been moved to macro.h,
we can stop including log.h in macro.h. This requires modifying source
files all over the tree to include log.h instead.
The functions are very similar, let's make them the same. If the first
argument to strextend() is NULL instead of extending a string we'll
allocate a fresh one and return that.
I didn't know that this helper existed… It is very similar to strdup_to_full(),
but all callers can actually be replaced by strdup_to(), which has more fitting
semantics.
It's a bit ugly to have both strdup_to() and strdup_to_full(). I initially
started with one variant, but then in some functions we want the additional
info, while in many other places, having 1 instead of 0 causes the return
value of whole chains of functions to be changed. It *probably* wouldn't cause
any difference, but there is at least of bunch of tests that would need to be
updated, so in the end it seems to have the two variants.
The output param is first to match free_and_strdup() and other similar
functions.
This commits adds version_is_valid_versionspec and uses it in
analyze-compare-version.c.
version_is_valid_versionspec differs from version_is_valid in that it acepts
empty strings and since valid characters in a version spec version are all
ASCII letters and digits as well as "-.~^", but ",_+" allowed by
version_is_valid are not.
Also give a more specific warning message on invalid characters.
While we are at it, replace the sloppy use of filename_is_valid() by the
less sloppy filename_part_is_valid() (as added by the preceeding
commit), since we don#t want to be too restrictive here. (After all,
version strings invalid as standalone filenames might be valid as part
of filenames, and hence we should allow them).
This is the function version of STARTSWITH_SET(). We also move
STARTSWITH_SET() to string-util.h as it fits more there than in
strv.h and reimplement it using startswith_strv().
strstrafter() is like strstr() but returns a pointer to the first
character *after* the found substring, not on the substring itself.
Quite often this is what we actually want.
Inspired by #27267 I think it makes sense to add a helper for this,
to avoid the potentially fragile manual pointer increment afterwards.
These combine strndup() + strspn()/strcspn() into one.
There are a bunch of strndupa() calls that could use similar treatment
(or should be converted to strdup[c]spn(), but this commit doesn't
bother with that.
