If we only receive very little data from the InputStream, try a second
Read() call to get more data. This works around tiny reads at input
buffer boundaries with the io_uring input plugin. These tiny reads
are inefficient, and we can afford to wait one more low-level I/O
iteration to finish (but not more).

When compiling with libfmt-11.1.0 and newer the following compile errors occur:

The error is due to the use of FMT_STRING. The libfmt team shared the following:
The correct way of using FMT_STRING is to wrap a format string when passing to a
function with compile-time checks (i.e. that takes format_string) as documented
in https://fmt.dev/11.1/api/#legacy-compile-time-checks.
Noting that FMT_STRING is a legacy API and has been superseded by consteval-based
API starting from version 8: https://github.com/fmtlib/fmt/releases/tag/8.0.0. It
looks like MPD is trying to emulate {fmt}'s old way of implementing compile-time
checks which was never properly documented because it was basically a hack. So the
correct fix is to switch to format_string and, possibly, remove usage of FMT_STRING.
The old way of doing compile-time checks (fmt::make_args_checked) was documented
in https://fmt.dev/7.1/api.html#argument-lists but it looks like MPD is not using
that API so the problematic uses of FMT_STRING have no effect and can just be removed.
The FMT_STRING has been removed in this change based on the fmt-7.1 API and now MPD is
successfully compile against the current libfmt-11.1.0 which highlighted the issue that
had been present in the codebase as it is now triggering the error, is legacy and was
not using the API for which FMT_STRING was aligned with.
libfmt 10 doesn't know how to format a StringView, and doesn't cast to
std::string_view anymore. The StringView class has been removed from
MPD 0.24 completely, and this is a stable-branch-only workaround.

std::all_of becomes constexpr in C++20. I'm not sure it results in better
performance.

The former has been deprecated by C++14. They are also the same.
From the standard:
The contents and meaning of the header<cinttypes>are the same as the C
standard library header<inttypes.h>, with the following changes:
-The header<cinttypes>includes the header<cstdint>instead of<stdint.h>,and
—if and only if the typeintmax_tdesignates an extended integer type
(6.7.1), the following functionsignatures are added:intmax_t
abs(intmax_t);imaxdiv_t div(intmax_t, intmax_t);which shall have the same
semantics as the function signaturesintmax_t imaxabs(intmax_t)andimaxdiv_t
imaxdiv(intmax_t, intmax_t), respectively.

According to the C++11 and C++17 standards, both files are identical.

Eliminates a number of allocations, because callers don't need to copy
the strings to a newly allocated buffer only to null-terminate them.
And most callers don't need to have a null-terminated string.
Commit b3a458338a added a LocateUri()
call to several playlist commands, which applied InputPlugin URI
scheme verification to playlist URIs. This broke the SoundCloud
playlist plugin which uses "soundcloud://" URIs for which no input
plugin exists.
This commit allows the caller to specify the kind of plugin which
shall be used to verify the URI. Right now, only "input" is
implemented; "storage" uses the "input" verification for now; and
"playlist" has no verification at all (for now).
