fd3c6992d9 fileio: read_virtual_file() don't tweak buffer for returning it when we aren't returning it
Let's avoid some redundant work.

Moreover, let' not check for NUL bytes in the buffer if we don't return
the buffer.

136f12a26a fileio: read_virtual_file(): exit once the max_size limit is reached

1b5e91a8d2 fileio: if we try to read a file larger than SIZE_MAX this is not a problem if a max_size is specified
i.e. 32bit userspace reading /proc/kcore on a 64bit kernel with max_size
should not needlessly fail.

f5e775973a sd-device: use strjoina() more again in sd_device_new_from_subsystem_sysname()
This reverts a major part of: e17c95af8e

Using format strings for concatenating strings is pretty unefficient,
and using PATH_MAX buffers unpretty as well. Let's revert to using
strjoina() as before.

However, to fix the fuzz issue at hand, let's explicitly verify the two
input strings ensuring they are valid path names. This includes a length
check (to 2K each), thus making things prettier, faster and using less
memory again.

8fd67ab5a3 man: reword description of BUILD_ID in os-release
Our description was pretty hard to parse. Let's replace it with a description
loosely based on a fairly clear description written by a distro that actually
uses BUILD_ID:

3ca606d103 man: add example os-release mangling in python
This is also not entirely obvious. I think the code I came
up with is pretty elegant ;] The final part of of the code that makes
use of the parsed data is kept very similar to the shell code on purpose,
even though it could be written a bit more idiomatically.

e839ebe551 man: add an example how to correctly read os-release in shell
This is not entirely obvious.

The logic of how to interpret the fields applies in any language, so drop the
pointless mention of C or shell.

00e3abe024 man: reorder fields in os-release
Let's order the fields from the most general to least: os name, os variant, os
version, machine-parseable version details, metadata, special settings. I added
section headers to roughly group the settings. The division is not strict,
because for example CPE_NAME also includes the version, and PRETTY_NAME may
too, but it still makes it easier to find the right name.

Also split out Examples to separate paragraphs:
almost all descriptions had "Example:" at the end, where multiple
examples were listed. Splitting this out to separate paragraphs
makes the whole thing much easier to read.

Add missing markup and punctuation while at it.

About
- If not set, defaults to <literal>NAME=Linux</literal>.
+ If not set, a default of <literal>NAME=Linux</literal> may be used.
and similar changes: in many circumstances, if this is not set, no value should
be used. The fallback mostly make sense when we need to present something to the
user. So let's reword this to not imply that the default is necessary.

135400276c oom: log one-time warning if kernel doesn't provide memory.swap.current
The kernel can be compiled without support for any memory.swap.* files, or
it can be disabled at boot time with the 'swapaccount=0' boot parameter,
so if the file doesn't exist log warning indicating the kernel doesn't
support the file and the user may need to try using the 'swapaccount=1'
boot param.

Note that the actual error from the call to fopen() is ENOENT, but
that is translated into ENODATA in cg_get_attribute_as_uint64()

0de2fd1870 psi: update is_pressure_supported to read file

264f0afe0d log: add log_once() and log_once_errno() macros
These macros will log a message at the specified level only the first time
they are called. On all later calls, if the specified level is debug, the
logs will be suppressed; otherwise the message will be logged at debug.

f78ad5f046 test: enable fuzz regression tests by default
This ensures that the fuzz test code is also built by default.
It also increases the test coverage a bit. Compiling the tests
*with* sanitizers is painfully slow, so this is not enabled. But
just compiling them sauté is hardly noticable. Running the tests
increases the test count and runtime:
  622 tests, 26 s
to
  922 tests, 35 s
I think this is acceptable.
