Updated to version 3.10.0. Changelog :
3.9.2 -> 3.10.0 :
- Legacy Makefile renamed to Makefile.legacy, will be removed eventually.
- Fix 'make dist' and 'make distcheck' to produce a usable release tarball.
- Fix 'olddir' usage with wildcard in the middle of path in the pattern
  definition when the pattern did not match any log file.
- Remove half-rotated files when rotation of particular log file is skipped
  because of an error during copy or compression.

It's not in the official changelog, but compilation errors also have been
fixed for NetBSD, so patches/patch-config.c is not necessary anymore.
