More updates from Bernhard Fischer
- flag rrd_resize's old file with RRD_COPY
- cleanup error-handling pathes in rrd_update and fix a few typos in
comments
- rrd_close(): implement printing mincore results for the rrd if
DEBUG=2 was defined
- rrd_open(): madvise start addresses need to be page-aligned; implement
alternative path to the fine-grained (i.e. exact) madvise by flagging
just the first two pages as needed (see TWO_PAGES). Implement
alternative path that records the last madvise()ed area to avoid
redundant calls to madvise() on identical areas (due to
page-alignment constraints) -- see CHECK_MADVISE_OVERLAPS. Implement
path for USE_DIRECT_IO.
- configure: add check for O_DIRECT flag to open(2). Add option
--enable-direct-io. Add _GNU_SOURCE to CFLAGS to silence warnings
about chroot which is marked LEGACY since SUSv2 and is a non POSIX
extension. Make checks for posix_fadvise() dependant on
--disable-mmap, since we do not need fadvise for the mmap case.
