System headers should be included with <...>, our own headers with
"...". Offenders tracked down with an ugly, brittle and probably
buggy Perl script. Previous iteration was commit a9c94277f0
.
Delete inclusions of "string.h" and "strings.h" instead of fixing them
to <string.h> and <strings.h>, because we always include these via
osdep.h.
Put the cleaned up system header includes first.
While there, separate #include from file comment with exactly one
blank line.
