krb5_get_init_creds_opt_set_change_password_prompt() was being ignored by
krb5_init_creds_step() which broke pam_krb5 tests. MIT doesn't handle password
expiration within krb5_init_creds_step(), instead deferring to higher level
functions such as krb5_get_init_creds_password(). However, Heimdal kinit uses
krb5_init_creds_step() directly and thus requires this behaviour to be
implemented to pass its own tests.
Adds support for "hard" aliases when initially authenticating, that is,
allowing a client or server principal to be known by many names without
requiring that the client support name canonicalization.
In order to avoid changing the behavior for other backends such as Samba, this
is implemented in the HDB backend rather than the KDC.
To use, add an alias for both the client and TGS ("krbtgt") principals using
kadmin. This behavior is unchanged if name canonicalization is enabled.
This fixes compilation with -Wstrict-overflow=2.

The size of portstr is too small to print an integer.
Instead just let snprintf do the work.
This fixes building with GCC 7.1

The Solaris auxval test fails, because Solaris uses different preprocessor
symbols (and numbers) for its UID and GID auxval types.
Note that issuid() could simply be an alias of issetugid() on Solaris, so
perhaps this is not necessary.
it turns out that we don't need to tell lex we don't plan to use unput;
we can just.... not use unput. however, if we're flex, use the command
line option if it's available, to avoid warnings

In VC15 GetVersionEx has been deprecated. In order to continue to

(available since Win2K).
Inline helper functions used in latest Win10 SDK to simplify code.
Zero out the DES_cblock structure instead of the (not yet used at this point
in the function) key schedule. The contents could potentially be left
on the stack in the case of an error return from _gssapi_verify_pad().
We generally clear out the cryptographic key and key schedule from
local variables before relinquishing control flow, but this case was
missed. Reported by jhb@FreeBSD.org.

The iovec encryption code doesn't handle 0 length iovecs correctly.
Instead of just skipping them, _krb5_evp_encrypt_iov_cts() will spin
on the 0 length iovec.
Modify the _krb5_evp_iov_cursor_expand helper so that iovec expansion
simply skips 0 length iovecs, and make _krb5_evp_iov_cursor_nextcrypt
do the same.
