Implementation of gss_set_neg_mechs() and gss_get_neg_mechs() as defined in RFC
4178. New gss_release_cred_by_mech() API for dropping a credential from a
mechanism glue credential.
SPNEGO uses the callback function acceptor_approved() in order to determine
which mechanisms to advertise to the initiator in the case that the initiator
sent an empty initial context token. Prior to this commit, that function was
not passed in the acceptor credential (if present), so always uses a default
credential. For correctness, we should only advertise the availability of
mechanisms for which we have a credential.
Refactor plugin framework to use a single list of loaded plugins; add a new
plugin API where DSOs export a load function that can declare dependencies and
export multiple plugins; refactor kadm5 hook API to use krb5 plugin framework.
More information in krb5-plugin(7).
Apple's Heimdal impelmentation uses a number of utility functions for
allocating names and credentials, to avoid calling malloc or calloc directly.
Import them.
Implement the GSS-API credential store API extensions defined by MIT here:
https://k5wiki.kerberos.org/wiki/Projects/Credential_Store_extensions
Note: we kill off gss_acquire_cred_ext() here. This was never a public API,
although mechanisms could have implemented it and I briefly used it in my
BrowserID prototype mechanism. gss_acquire_cred_ext_from() occupies the place
in the dispatch table where gss_acquire_cred_ext() used to, but this structure
was never visible outside Heimdal (i.e. it is only used by internal
mechanisms);
(Mechanisms that need to accept arbitrary key/value dictionaries from
applications should now implement gss_acquire_cred_from().)
SPNEGO uses the callback function initiator_approved() in order to determine
mechanism availability. Prior to this commit, is not passed in the initiator
credential, so it always uses a default credential. This breaks SPNEGO if a
non-default credential (such as one acquired with
gss_acquire_cred_with_password()) is used. This commit addresses this.
gss_krb5_set_allowable_enctypes() was declared with an array of int32_t types
representing the enctype list, but the definition had an array of krb5_enctype.
Whilst these are likely the same size, they may not be. On the receiving end,
allocate an array of krb5_enctype.
* check `ctx->gc_ctx` in `gss_inquire_context()`
* check `gm_inquire_cred != NULL` in `gss_inquire_context()`
* check `min_lifetime` in `gss_inquire_cred()`
* check `gm_inquire_cred_by_mech != NULL` in `gss_inquire_cred_by_mech()`
* set mech error in `gss_inquire_cred_by_oid()`
* don't clobber error in `gss_inquire_cred_by_oid()`
* don't pass NULL minor_status to `gss_krb5_free_lucid_sec_context()`
* allow NULL ccache in `gss_krb5_ccache_name()`
* NULL names OK in `_gss_find_mn()`
* allow empty names in `gss_import_name()` (removes `input_name_buffer` length
check). to support ANONYMOUS. in `gss_import_name()`, ignore mech name
import failure as long as it's possible to import the name in some other
mechanism
* better argument validation in `gss_export_sec_context()`
* in `gss_compare_name()`, check `mn2 != NULL`
* check `gss_add_oid_set_member()` return code in `gss_indicate_mechs()`
* in `gss_destroy_cred()`, set output cred handle to `GSS_C_NO_CREDENTIAL`
* cast size_t to OM_uint32 where required
In the case that one name has no MNs and the second name only has an MN, then
the order in which the two names are passed in matters, but it shouldn't. Run
the comparison both ways.
Coverity determined that a NULL pointer segmentation fault could occur
if krb5_storage_emem() fails. Use krb5_enomem() to set an error message
on the context and do not perform further krb5_storage operations.

- Add --keepold/keepallold/pruneall options to various kadmin/ktutil
commands. Default behavior to "prune old keys".
- When setting keys for a service, we need to specify enctypes for it:
- Always use kadm5_randkey_principal_3() instead of the older
kadm5_randkey_principal().
- Add krb5_string_to_keysalts2(), like MIT's krb5_string_to_keysalts(),
but with a context, and simpler.
- Add --enctypes options to various kadmin/ktutil commands.
- Add [libdefaults] supported_enctypes param with enctype[:salttype]
list.
- Add [realms] realm supported_enctypes param with enctype[:salttype]
list.
Default to aes128-cts-hmac-sha1-96:normal.
libhx509 is not built according to the same export and calling conventions
on Windows as the other libraries. This change declares and applies
HX509_LIB_FUNCTION, HX509_LIB_NORETURN_FUNCTION, HX509_LIB_CALL and
HX509_LIB_VARIABLE to lib/hx509.
As a result of this change the calling convention for exported functions
will be __stdcall instead of __cdecl.

If a memory allocation failure occurs, return an error instead of
triggering a segmentation fault.
