vcs-svn: allow 64-bit Prop-Content-Length
Currently the vcs-svn/ library only pays attention to the presence of the Prop-Content-Length field and doesn't care about its value, but some day we might care about the value. Parse it as an off_t instead of arbitrarily limiting to 32 bits for intuitiveness. So now you can import from a dump with more than 2 GiB of properties for a node. In practice that isn't likely to happen often, and this is mostly meant as a cleanup. Based-on-patch-by: David Barr <davidbarr@google.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com>
