[gss-genr.c]
Work around a problem in Heimdal that occurs when KRB5CCNAME file is
missing, by checking whether or not kerberos allocated us a context
before attempting to free it. Patch from Simon Wilkinson, tested by
biorn@, ok djm@

make the portable tree compile again - sprinkle unistd.h and string.h
back in. Don't redefine __unused, as it turned out to be used in
headers on Linux, and replace its use in auth-pam.c with ARGSUSED
[gss-genr.c]
GSSAPI buffers shouldn't be nul-terminated, spotted in bugzilla #1066
by dleonard AT vintela.com. use xasprintf() to simplify code while in
there; "looks right" deraadt@

[xmalloc.c xmalloc.h]
introduce xcalloc() and xasprintf() failure-checked allocations
functions and use them throughout openssh
xcalloc is particularly important because malloc(nmemb * size) is a
dangerous idiom (subject to integer overflow) and it is time for it
to die
