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.
Passing in the func, file and line information complicates the
interface. On top of that, it prevents forward declaring Hashmap in
strv.h, as we need to pass the macros everywhere that we allocate a
hashmap, which means we have to include the hashmap header everywhere
we have a function that allocates a hashmap instead of just having to
forward declare Hashmap.
Let's drop the file, func and line information from the debug information.
Instead, in the future we can add a description field to hashmaps like we
already have in various other structs to describe the purpose of the hashmap
which should be much more useful than having the file, line and function where
the hashmap was allocated.
This uses the same logic as similar verb suggestion for command line
utilities. Try to be helpful when the user entered something invalid
instead of just showing the prompt again.
The macro didn't properly parenthesize a caller-controlled argument.
For example: `STRV_FOREACH_PAIR(a, b, something ?: something_else)`
would expand to `typeof(*something ?: something_else)`, which would
cause compile failures

The current semantics of "filtered" in unit_is_filtered()
are actually the contrary of ListUnitsFiltered(). Let's
make things consistent, i.e. return true when the unit
shall be included.
Also, use the more correct type of 'const char* const*' for the input strv.
This requires adding the cast in a few places, but also allows to remove some
casts in others.
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().
The second argument to _printf_() specifies where the arguments start. We need to
use 0 in two cases: when the args in a va_list and can't be checked, and with journald
logging functions which accept multiple format strings with multiple argument sets,
which the _printf_ checker does not understand. But strv_extendf() can be checked.
This will be helpful in cases where we are repeatedly adding entries
to a long strv and want to skip the iteration over old entries leading
to quadratic behaviour.
Note that we don't want to calculate the length if not necessary, so
the calculation is delayed until after we've checked that value is not
NULL.
Plain strv_split() should not care if the strings contains backslashes
or quote characters. But extract_first_word() interprets backslashes
unless EXTRACT_RETAIN_ESCAPE is given.
I wonder how it's possible that nobody noticed this before. I think this
code was introduced in 0645b83a40.
Same idea as 03677889f0.
No functional change intended. The type of the iterator is generally changed to
be 'const char*' instead of 'char*'. Despite the type commonly used, modifying
the string was not allowed.
I adjusted the naming of some short variables for clarity and reduced the scope
of some variable declarations in code that was being touched anyway.
