We don't store trust type, attributes, and direction for subdomains
of the existing trust. Since trust is always forest level, these parameters
can be added as defaults when they are missing.
We store Kerberos realm configuration in cn=REALM,cn=kerberos,$SUFFIX.
Along other configuration options, this container has list of default
supported encryption types, in krbDefaultEncSaltTypes.
Fetch krbDefaultEncSaltTypes value on ipa-sam initialization and convert
discovered list to the mask of supported encryption types according to
security.idl from Samba:
typedef [public,bitmap32bit] bitmap {
KERB_ENCTYPE_DES_CBC_CRC = 0x00000001,
KERB_ENCTYPE_DES_CBC_MD5 = 0x00000002,
KERB_ENCTYPE_RC4_HMAC_MD5 = 0x00000004,
KERB_ENCTYPE_AES128_CTS_HMAC_SHA1_96 = 0x00000008,
KERB_ENCTYPE_AES256_CTS_HMAC_SHA1_96 = 0x00000010
} kerb_EncTypes;

We used to handle some of code paths to free memory allocated by the LDAP library
but there are few more unhandled. In addition, search result wasn't freed on successful
initialization, leaking for long time.

When trust is established, last step done by IPA framework is to set
encryption types associated with the trust. This operation fails due
to ipa-sam attempting to modify object classes in trust object entry
which is not allowed by ACI.
Additionally, wrong handle was used by dcerpc.py code when executing
SetInformationTrustedDomain() against IPA smbd which prevented even to
reach the point where ipa-sam would be asked to modify the trust object.
PASSDB API in Samba adds support for specifying UPN suffixes. The change
in ipasam will allow to pass through list of realm domains as UPN suffixes
so that Active Directory domain controller will be able to recognize
non-primary UPN suffixes as belonging to IPA and properly find our KDC
for cross-realm TGT.
Since Samba already returns primary DNS domain separately, filter it out
from list of UPN suffixes.
Also enclose provider of UPN suffixes into #ifdef to support both
Samba with and without pdb_enum_upn_suffixes().

Change user-add's uid & gid parameters from autofill to optional.
Change the DNA magic value to -1.
For old clients, which will still send 999 when they want DNA
assignment, translate the 999 to -1. This is done via a new
capability, optional_uid_params.
Tests included
https://fedorahosted.org/freeipa/ticket/2886
Since we use associatedDomain attribute to store information about UPN suffixes
and our own domain, searching subtree is going to return more than one entry.
Limit search for own domain by base scope as we only need to fetch our own
domain information here, not UPN suffixes.

With this change ipasam is able to ask for ipaNTHash generation and if
corresponding Kerberos key is available, will be able to retrieve generated ipaNTHash.

When developing and testing in the same environment, multiple re-installs
may be needed. This means previously issued and cached Kerberos credentials
will become invalid upon new install.
ipasam passdb module for Samba uses Kerberos authentication when talking to
IPA LDAP server. Obtained Kerberos credentials are cached during their lifetime.
However, the ccache is not removed automatically and if IPA setup is made
again, cached credentials are used, only to discover that they are invalid.
With this change invalid correctly obtained cached credentials are recognized
and, if LDAP SASL bind fails, new credentials are requested from the KDC.

With c43505b621725c9a754f0ee98318d451b093f2ed in samba git master
the function sid_check_is_domain() was renamed to sid_check_is_our_sam().
https://fedorahosted.org/freeipa/ticket/2929
SASL bind callback due to refactoring was referencing local variable which
didn't exist all the time. Fix that by including a copy of service principals
into ipasam long term private struct.
Rework ccache handling to avoid re-initing every time callback is called
Commit a6e29f23f09ba5b6b6d362f7683ae8088bc0ba85 in Samba changed id mapping
API in passdb interface to use 'struct unixid'. The change replaced three arguments
(uid, gid, type) by one (struct unixid). As result, ipa-sam became broken.
Without this change ipa-sam introduces stack corruption in Samba post 4.0.0alpha18
leading to corrupted security context stack as well and then crashing in setgroups(3).
