cb23a0345f idl: Add Windows event code ids
Add idl definitions for Windows Event Code Ids, and Logon Types. This
intial commit adds:

Event Ids
	4264	Successful logon
	4625	Unsuccessful logon

Logon Types
	 2	Interactive
	 3	Network
	 4	Batch
	 5	Service
	 7	Unlock
	 8	NetworkCleartext
	 9	NewCredentials
	10	RemoteInteractive
	11	CachedInteractive

The intention is to add Windows Event Codes to the JSON log messages, to
provide a common event identifier in mixed Windows and Samba networks.
And to assist security personnel with a windows background.

5c129351cc s4/librpc: Additionally accept unicode as string param in Py2
With the changes to make samba python code Py2/Py3 compatible there
now are many instances where string content is decoded.
Decoded string variables in Py2 are returned as the unicode type. Many
Py2 c-module functions that take string arguments only check for the
string type. However now it's quite possibe the content formally passed
as a string argument is now passed as unicode after being decoded,
such arguments are rejected and code can fail subtly. This only affects
places where the type is directly checked e.g. via PyStr_Check etc.
arguments that are parsed by ParseTuple* functions generally already
accept both string and unicode (if 's', 'z', 's*' format specifiers
are used)

idl file triggers pidl to generate the function table entry, which in turn then
triggers tables.pl to register this interface
./bin/default/source4/librpc/gen_ndr/tables.c. We could for example do the same

e42f12c6be s4:lib/http: let http_read_response_send/recv() also consume the body if it fits into a max value
We need to consume full HTTP responses from the socket during the
authentication exchanges, otherwise our HTTP parser gets out of sync for
the next requests.

This will be important for gensec mechs which use an even number
for authentication packets.

I guess this should be done just based on the Content-Length value and
not based on the response code.

So far I saw bodies with 200 and 401 codes.

e5f2dfacae build: correct package dependencies

    # auth/credentials/wscript_build:
    bld.SAMBA_LIBRARY('samba-credentials',
                      public_headers='credentials.h',

Now, credentials.h #includes <util/data_blob.h> and therefore,
samba-credentials.pc must have a Requires: samba-util.

Similarly for other parts.

ace23643d1 CVE-2015-5370: s4:librpc/rpc: avoid using dcecli_security->auth_info and use per request values
We now avoid reusing the same auth_info structure for incoming and outgoing
values. We need to make sure that the remote server doesn't overwrite our own
values.

This will trigger some failures with our currently broken server,
which will be fixed in the next commits.

The broken server requires an dcerpc_auth structure with no credentials
in order to do an alter_context request that just creates a presentation
context without doing authentication.
