There are more than enough calls doing string manipulations to deserve
its own files, hence do something about it.
This patch also sorts the #include blocks of all files that needed to be
updated, according to the sorting suggestions from CODING_STYLE. Since
pretty much every file needs our string manipulation functions this
effectively means that most files have sorted #include blocks now.
Also touches a few unrelated include files.
After all it is now much more like strjoin() than strappend(). At the
same time, add support for NULL sentinels, even if they are normally not
necessary.
If we scale our buffer to be wide enough for the format string, we
should expect that the calculation was correct.
char_array_0() invocations are removed, since snprintf nul-terminates
the output in any case.
A similar wrapper is used for strftime calls, but only in timedatectl.c.
If the format string contains %m, clearly errno must have a meaningful
value, so we might as well use log_*_errno to have ERRNO= logged.
Using:
find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/'
Plus some whitespace, linewrap, and indent adjustments.
Not all switch roots are like base_filesystem_create() wants them
to look like. They might even boot, if they are RO and don't have the FS
layout. Just ignore the error and switch_root nevertheless.
base_filesystem_create() should have logged, what went wrong.
