tree-wide usage of %m specifier instead of strerror(errno)

Also for log_error() except where a specific error is specified

e.g. errno ? strerror(errno) : "Some user specified message"
journal: when appending to journal file, allocate larger blocks at once
journal: make table const
journald: keep statistics on how of we hit/miss the mmap cache
journal: optimize bisection logic a bit by caching the last position

This way we can do a quick restart limiting a bit how wildly we need to
jump around during the bisection process.
journal: fix iteration when we go backwards from the beginning of an array chain element
journal: allow journal_file_copy_entry() to work on non-local files
journal: add a test case for flushing messages out of a series of journal files into a single new one
journal: simplify pre-allocation logic

let's just do a single fallocate() as far as possible, and don't
distuingish between allocated space and file size.

This way we can save a syscall for each append, which makes quite some
benefits.
journald: mention how long we needed to flush to /var in the logs
logind: log which process is delaying suspend and not closing locks

Revert "socket-proxyd: Add --listener option for listener/destination pairs."

This reverts commit adcf4c81c58511b67644e17fa743d1729d3c9ccf.

We have a better solution for the problem of making two processes run in
the same namespace, and --listener is not needed hence and should be
dropped.
