commit 599511589ca7ddb3b2eac8d3aa5b0b38be7a7691

libtirpc: allow larger ticket sizes with RPCSEC_GSS
libtirpc currently limits RPCSEC_GSS args to MAX_NETOBJ_SZ (1024) bytes.
This causes problems when you try to use large krb5 tickets, such as
those handed out by MS' Active Directory when the user has a large PAC.
This patch backports a set of changes from librpcsecgss which fixed this
problem there. It declares a new routine specifically for encoding
gss_buffer_t's and has the various auth_gss routines use that instead of
calling xdr_bytes directly.
An RPC_SLACK_SPACE constant is defined and added to the buffer length to
get a max buffer length to pass to xdr_rpc_gss_buf for the appropriate
callers.
This seems to fix the bug reported here:

commit 89323aafc77e1a40800332fb135888782b1bfee6

libtirpc: don't call abort() in the AUTH_UNIX creation codepaths
When there are problems creating an AUTH_UNIX auth handle, libtirpc will
sometimes call abort(). It's bad for a library to do this since
decisions about how to handle errors are better left up to the
application and abort() generally causes the app to crash and dump core.
Make it so that these functions return NULL instead in these situations.
authunix_create already returns NULL for other error conditions so it
seems like an appropriate way to handle errors in these codepaths.
Have authunix_create and authunix_create_default set appropriate errors
in the rpc_createerr struct. It seems a little odd to do this since
rpc_createerr is supposed to report information about why CLIENT
creation failed, and the problem here is in creating an AUTH handle.
authgss_create does this already however, so there is some precedent.
While we're at it, it's also bad for libraries to log to stderr. It's
possible that a daemon is calling here and it has closed stderr and is
resuing fd 2 for something else. Rip out the warnx calls from these two
functions to make sure that they don't cause problems.
