libnfsidmap-020 available

[Kevin Coffman]

A new version of libnfsidmap is now available from
http://www.citi.umich.edu/projects/nfsv4/linux/libnfsidmap/libnfsidmap-0.20.tar.gz

Changes since libnfsidmap-0.19:

A patch from Michael Marineau <marineam at google.com>:

When resolving between a group name and the local gid the group's data
structure is stored in a buffer the size of
sysconf(_SC_GETGR_R_SIZE_MAX) which is usually 1024. This size is to
small for any group larger than about 100 users. When the limit is
reached name resolution failed and the default nogroup value is used.

The attached patch fixes this issue by attempting larger and larger
buffer sizes until the group structure fits starting with
sysconf(_SC_GETGR_R_SIZE_MAX). If the group fits in the default size
the behaviour is the same.
